Tutorial Photoshop CS6 3D

Photoshop CS6 3D Tutorial

Kirk Nelson

Photoshop has never been known for its 3D abilities. It is really better known as Adobe’s primary-pixel-pusher. The inclusion of 3D objects and Repousse in previous versions marked interesting forays into the realm of raytraced three dimensions. But the cumbersome workflow and less than stellar results turned away many who would otherwise welcome the new tools into their production workflow. In Photoshop CS6, Adobe has taken great pains to overcome that perception. New features, enhanced workflow, and smoother, more reliable performance all come together to make the 3D features of CS6 extended something worth paying for.
Gone is the term “Repousse” and good riddance! It has been replaced with the much more sensible term, “3D extrusion.” That’s a term that even we can figure out what it means! Adobe has also created an innovative new approach to modifying the properties of the 3D elements. While using the 3D tools, objects have their own modifier displays, such as transformation cages and bevel adjustments that can be accessed right on the canvas. Even the smoothness of shadows can be adjusted by dragging on the shadow! The old slider bars are still there, but it is entirely possible to create, move, edit and adjust 3D objects without ever having to visit the panels.
This tutorial will demonstrate some of the new 3D features and workflows available in CS6. For the project, we took some inspiration from the Inception movie posters and decided to spell the word Bicubic in large letter shaped buildings within a city. (Because the bicubic smoother interpolation is used for enlarging images in Photoshop!) Fair warning, this tutorial does contain some rather advanced compositing steps that are aimed at the more experienced user, but those are not the focus of the project. The primary point is to explore the 3D features and workflow, so most of the instruction is spent on those steps.

Bicubic Tutorial Steps

Step 1 - Stock Image Selection
The success of the entire effect rests on the quality of the base image. The shot needs to be drastically vertical so the roofs and building shapes are clearly visible. A lower, more oblique angle and the letters will not be recognizable. The shot you see here is from (#826018). Then use the new crop tool in CS6 to trim it down to the working area shown here.

Step 2- Bicubic Buildings
Add in the text using a simple no-serif font, Arial works nice in this case. Then with the type tool still active check the Options bar for a new 3D Extrude icon. Press it and Photoshop switches to the 3D workspace and extrudes the type. Select the Bevel from the Shape presets and set the Extrusion Depth to 1.25.

Step 3 - Build a Ledge
At the bottom of the workspace, you can switch from one layout to the other, using three tiny icons which represent the Mobile size, Tablet size, and Desktop size designs. When you change from one layout to another, the corresponding CSS is applied to the document displayed in Dreamweaver’s workspace. Remember, you’re only working on one HTML file, but because Dreamweaver creates three sets of styles, you can rearrange and resize the elements to create three different layouts.

Step 4 - Turn Entire Buildings on End
With the Bicubic 3D text still targeted press the 4th icon in the properties panel for Coordinates. Enter 90 into the X rotation field to turn the letters up on their end. Then go to the 3D menu and choose Snap Object to Ground Plane.

Step 5 - A Different Perspective
Click on the Current View line in the 3D panel and make sure the Move Tool is active. Photoshop immediately activates the 3D camera tools. Use these to rotate, pan, and zoom around the scene until the buildings fit into the proper perspective.

Step 6 - Break up the Block
Currently the entire word is considered one single mesh to Photoshop. In order to assign different textures and properties to the individual buildings, they must each be a unique 3D element. To do this go to 3D>Split Extrusion. Notice in the 3D panel that Photoshop creates a separate 3D object for each letter.

Step 7 - Create Textures
Now it’s time to turn some attention to the texture maps. Open the original stock image again and find a clear, unobstructed view of a building side. Create a selection of that side and copy it to a new document. Then use the new Perspective Crop tool (found behind the regular Crop Tool)  click on each corner of the map and the tool will  remove the perspective and square off the texture.  Continue with this process until you have enough side and roof textures for each building.

Step 8 - Basic Texture Mapping
Back in the project file, open up the 3D object layers in the 3D panel until you can see the Material entries. Select the “B Front Inflation Material” and in the Properties Panel click on the document icon next to the Diffuse attribute. Load one of the roof materials to map here. Use the same method to map a side texture to the Extrusion material. For the Bevel material, click on the color chip to assign a color that can be sampled from the adjoining textured surface. Continue on until all the letters are fully mapped.

Step 9 - Move the Sun
Select the “Infinite Light 1 item” in the 3D panel and use the on-canvas editor to adjust the light direction to match the base city image, so the light is coming from the top left. Use the Add Light icon (in the base of the 3D panel) to create another infinite light to serve as a fill light. Reduce the intensity of this light and align it to light up the shadow areas so they are not fully black.

Step 10 - There’s a Render Button!
Press the Render button (no more quality drop down menu to start a render!) in the base of the Properties panel and wait as Photoshop renders out the image. Depending on your system strength this might take a while. Notice that CS6 even has a Time Remaining status bar in the lower left corner.

Step 11 - Let’s Start Compositing
At this point you can Rasterize the 3D layer (Layer>Rasterize>3D) to make it available for filters and painting tools that will help in the compositing process. Next, use the Pen Tool to trace around the foreground buildings. Make the full path go up and around the rendered buildings and use the path as a vector mask on the 3D buildings. The new letters should tuck nicely in behind the foreground buildings.

Step 12 - Shuffle Buildings Around
The background image needs some adjustments so the render fits seamlessly into it. Duplicate the layer and work on the copy. Create a selection around the tall white building in the lower right. Use the New Content Aware Move tool to shorten the building so it doesn’t obscure the new buildings. Otherwise, Clone Stamping and Content Aware Fill are the primary tools for this step to remove or relocate buildings that are in the way of the new letter buildings. Simulated shadows can be created by creating a feathered selection and using the burn tool.

Step 13 - Lighting Adjustment
It’s unlikely the rendered lighting will exactly match the background image, so use a Curves adjustment layer to correct any discrepancies. Clip the adjustment layer to the rendered layer by pressing the first icon at the base of the Properties panel. Clip a Shadow layer on top of this (by holding down the alt/opt key while clicking between the layers) and use a black to transparent linear gradient to add shadows to the base of the buildings.

Step 14 - Collect the Roof Clutter
While the rendered textures for the roofs are impressive, they don’t quite look photo realistic. Create a new Roof Patch group for each building to start copying additional architectural elements from elsewhere in the image. Open the original stock photo and use it as the source for the Clone Stamp Tool to clone elements into the project file. There are plenty of cranes, AC units and vents available to choose from!

Step 15 - Highlight Blowout
The original photo is a little overexposed. To match that condition create a merged layer at the top of the layer stack by holding down the alt/opt key and going to Layer>Merge Visible. Then ctrl/cmd click the rendered layer’s thumbnail to load that shape as a selection. Hold down alt+ctrl+shift (opt+cmd+shift) and click the mask thumbnail to intersect this with the mask shape. Use the resulting selection as a mask on the merged layer. Set the blending mode to linear dodge and reduce the opacity to around 50%.

Step 16 - Final Effects
Add a Hue/Saturation adjustment layer to the top of the stack. Check the colorize box and adjust the sliders to get a sepia hue (39, 32, -1 works well). Add a Vignette layer on top and fill it with 50% grey through the Edit>Fill command. Run the Lens Correction filter and look in the custom tab for the slider to add a dark vignette. Finally set the blend mode to Overlay to make the grey invisible.

Remember, the key to creating responsive designs is to position the same divs for best display in each of the three layouts. For example, in the mobile version, the best practice is to create a single-column layout, but in the tablet and desktop versions, you may want to position the same divs to create two or more columns.

Here is the Final Image.

Other Helpful Tips

Get some Help from Vanishing Point
It can be somewhat challenging to get the 3D ground plane to match the photo perspective. Here’s a tip that can help. First create a new layer and go to the Vanishing Point filter. Draw out a grid that matches the ground of the photo. In the options flyout menu, select Render Grids to Photoshop. Then press OK and you will have a grid to help visually align your 3D Ground Plane!

Render selection
It’s likely that the initial setup of textures and lighting isn’t exactly what you want. Chances are you will need to render a few times to tweak settings to get everything just right. Don’t waste time rendering the entire scene time and time again. Create a selection of the area you are working on before pressing the render button. Photoshop renders only the selected pixels. This can be a huge time saver!

Secondary 3D view
CS6 includes several new interface elements when working with 3D. One of the most helpful is a secondary view of the 3D object. Go to View>Show>3d Secondary View to get the floating window showing the 3D object from another perspective. This can be extremely useful when positioning objects and lights.

Creating Texture Maps
Texture mapping is an art unto itself! The basic idea here is to copy a portion of the photo and use it as a wrapper on the 3D element. To make sure the texture maps are seamless, use the Offset filter (Filter>Other>Offset) to wrap the texture around the canvas sides so you can see how the edges join together.

Editing UV properties
If a texture appear stretched or squashed when applied to the building sides, the UV properties need to be adjusted. Frequently a texture needs to be repeated many times as it wraps all the way around the building. Click on the same icon used to load the texture map and select Edit UV Properties. This brings up the Texture Properties. Adjust the scale and offset values needed.

Clone from a Different Document
Did you know the clone tool can source from one document and paint in another? While creating the architectural elements for the roof “clutter” in this project, open the source stock image side by side with the project file. With the Clone Stamp tool alt/opt click in the stock image and then go to the project file to paint. Photoshop clones pixels from one document to another!


This is really just the tip of the iceberg when it comes to the potential of the new 3D features in Photoshop CS6. The very same technique used here to map a texture to a diffuse color of an object can be used to control many other properties of the 3D objects. Specular maps can be used to make certain areas appear shiny while others are matte. Opacity maps control the visibility of a surface; these can be utilized to create invisible areas or holes in a surface that would not be possible to create otherwise. Mapping a grunge texture to the Roughness property can go a long way to breaking up the perfect computer generated appearance of a rendered surface. The list goes on and on.
The possibilities don’t end with the texture mapping either. The extrusion options are not limited to a straight extrude with a beveled edge. The twist and bend extrusions make it possible to create springs or twisted shapes. The revolve extrusion allows for easy creation of rounded objects like glasses or bottles. Additionally, Photoshop can import several popular 3d files from other packages to work with as well.  The support of improved reflections and refractions, Image Based Lighting, as well as in-camera depth of field makes it possible to create photorealistic renders in Photoshop, it’s easier than we ever imagined.
Most 3D artists will tell you that 90% of their rendered work ends up in Photoshop anyway. When time is money and you are on a deadline, it is much easier and faster to clone out a stray polygon or make lighting corrections with curves than it is to tweak a setting and re-render an entire scene again. So being able to create or edit 3D work in the same program used to retouch it means fewer return trips between applications and less digging through folders to find the correct rendered file. This streamlines and consolidates the production pipeline.
Photoshop’s 3D features are now worthy of being noticed. If you’ve never tried them before, now is the time. With CS6, these tools have leveled up!

Tutorial Photoshop CS6 Adobe Camera RAW

Adobe Camera RAW 7.0 Tutorial for Photographers – Photoshop CS6

Whether you’re a seasoned pro or fresh out of the gate with your first quality digital camera, shooting your photographs in RAW is an absolute must to achieve higher quality results with your photographs. In the following tutorial and Photoshop CS6 feature run-down, we’re going to cover all the new features in Camera RAW 7.0 that I think are the best and ones that you’re going to use the most! Drop a comment if you have additional questions or suggestions!
One of my favorite things about the Camera RAW editor is that you can open it with either Photoshop or the Bridge. This allows you to work on RAW files in the Bridge while Photoshop batch processes or renders large images, etc… To open an image using Camera RAW in the Bridge simply select that image and hit Cmd/Ctrl + R.
Adobe Camera RAW 7 Photoshop CS6 Tutorial for Photographers

Introduction to Camera RAW

The Camera RAW editor is included with Photoshop. If you purchased (or ‘acquired’) Photoshop, you will have Camera RAW. Camera RAW allows you to edit images outside of Photoshop in a very refined way, much different from the normal interface of Photoshop. Most importantly, Camera RAW allows us to pass images into Photoshop where we can further edit them!
TIP: In addition to your camera’s native Camera RAW files, you can use the Camera RAW editor to edit JPEG and TIFF files by right clicking those files in The Adobe Bridge and choosing “Open in Camera Raw…”
Let’s jump into this tutorial!
Adobe Camera RAW 7 Photoshop CS6 Tutorial for Photographers

Opening RAW Files

To open a Camera RAW file using Photoshop, go File>Open and double click the RAW file you would like to open. NOTE: RAW file formats vary depending on the camera you use. Canon is .CR2, Nikon is .NEF, Adobe even has a RAW format (which I love!) .DNG, and the list goes on and on. Check out your camera’s manual for info.

Camera RAW Dialog

What you will see is the Camera RAW editor. Long story short, Adobe did some serious overhauling to this dialog and you will be able to beautifully push the limits of your images beyond anything you could in previous versions of Adobe Camera RAW. Things like artifacting, chromatic aberrations, and noise all are kept under much, much better control in Adobe Camera Raw 7.0, or ACR7 as we’ll call it.
Adobe Camera RAW 7 Photoshop CS6 Tutorial for Photographers

Convert to 2012 Process (Camera RAW 7)

The image that I opened with Camera RAW has previously been edited in ACR6-which ships with Adobe Photoshop CS5. We want to edit this in ACR7 and we can do this by telling Camera RAW to update this image to the current process (Adobe Camera RAW 7 is current!) by clicking the little exclamation point in the bottom right of the image.
Adobe Camera RAW 7 Photoshop CS6 Tutorial for Photographers

New Sliders, New Editor

The panel of sliders on the right will update and ACR7 will try to use settings that are somewhere near what the image previously had. Typically you will need to make some adjustments to tweak your picture a bit more.
Adobe Camera RAW 7 Photoshop CS6 Tutorial for Photographers


The sliders in ACR7 all have the ability for positive and negative values for any of these settings (plus/minus Whites, Blacks, Contrast, etc… etc…) and allows for a much broader range of option. I’m going to push my Exposure to 1.80. Exposure controls the mid-tones in your image. All that stuff in the middle of your histogram.
Adobe Camera RAW 7 Photoshop CS6 Tutorial for Photographers


Contrast is Contrast and I’m going to bump mine up to an even +55. Highlights control the brighter portion of your image (we’ll talk about “Whites” in just a second) and because the sky is getting blown out here I’m going to pull this way back, all the way back to -100.
Adobe Camera RAW 7 Photoshop CS6 Tutorial for Photographers


The Shadows slider is really going to target the darker portions of the image. I want to pour a little more light into the shadows so I’m going to push this up to +55. NOTE: The more you darken your highlights and brighten your shadows the less contrast your image will have. Contrast and Curves will be there to help you.
Adobe Camera RAW 7 Photoshop CS6 Tutorial for Photographers

Whites & Blacks

The Whites and Blacks sliders target the highlights/shadows in a much tighter fashion than the Highlights/Shadows sliders did. There is a focus specifically on both ends of the histogram. Bright, bright and dark, dark areas of the image will be targeted, respectively. I am going to set my Whites to -100 and my Blacks to +50.

Artifacting, Chromatic Aberrations, & Noise Reduction

Other than the huge slider update and the massive back end performance boost with the much better prevention of artifacting, aberration, and noise worked in, ACR7 has included much better control of color and noise when using the Graduated Filter and Adjustment Brush tools.
Adobe Camera RAW 7 Photoshop CS6 Tutorial for Photographers

The Graduated Filter Tool

Using the Graduated Filter tool (G), I will introduce much more orange and pink into the sky by boosting the Temperature and Tint to +20 and +100, respectively. Drag a gradient straight down from the top of the image to apply the effect. I also reduced the Exposure and boosted the Contrast.
Adobe Camera RAW 7 Photoshop CS6 Tutorial for Photographers

The Adjustment Brush

By adjusting the Tint and a bunch of the other sliders I am able to brighten and pour in a bunch of contrast over the sand to give a neat look to the photograph. Check out the screenshot for all the settings. Also note that the adjustment brush gives you the option to “Reduce Noise”, this is extremely useful when brightening very dark areas of your image where noise tends to start appearing.
Adobe Camera RAW 7 Photoshop CS6 Tutorial for Photographers


To correct and reduce the vignette around this image select the Hand tool (H) to view the normal editing options and select the Lens Correction icon near all the other icons and choose the “Manual” tab and increase or decrease your vignette “Amount” until it looks just right.
Adobe Camera RAW 7 Photoshop CS6 Tutorial for Photographers

Workflow Options Dialog

Not necessarily new to ACR7, but very important to your success using the Camera RAW editor is workflow options link at the bottom of the dialog box. Click it to open a little dialog box of goodness.
Adobe Camera RAW 7 Photoshop CS6 Tutorial for Photographers

Opening Your Image in Photoshop

In this dialog box you can choose the color space you want to work in (stay away from sRGB!), the bit depth (if your computer can handle it, 16-Bit is much, much better), the size of the image to be opened, and much more! Hit OK to commit the changes and then either press “Open Image” to open it in Photoshop CS6 or hit “Done” to save those Camera RAW changes to that RAW file and close the ACR7 editor.

Tutorial Photoshop CS6 Blur Gallery

Photoshop CS6 Blur Gallery Tutorial

The new Blur Gallery in Photoshop CS6 offers tools that provide intuitive and creative ways to manipulate depth of field and create bokeh effects.
One of my favorite features introduced in the Photoshop CS6 beta is without a doubt the Blur Gallery. This collection of three brand new filters allows for photo-realistic depth of field adjustments via an interface which allows you to place and manipulate controls directly on the image area.
Photographers rely on focal length, subject distance and aperture to determine in-focus and blurred areas of an image. Yet there are times when technical constraints make a desired effect difficult to achieve. And that's where these new tools come in handy.
Unlike the blur options in previous versions of Photoshop, the Blur Gallery filters are designed specifically to produce a selective focus effect. The Blur Gallery is comprised of three filters; Field Blur, Iris Blur and Tilt-Shift. In addition there are a separate set of Blur Effects that let you create specular highlights mimicking the circular bokeh effect produced by lenses. In this article I’ll show you how these tools work and hopefully inspire you to start using them on your own images.
You can find the new blur tools by going to Filter>Blur. Selecting one of the top three options (highlighted in red) will open the new Blur Gallery. The Blur Gallery opens in a full size window that temporarily replaces your regular workspace. Panels along the right give you access to all three of the blur filters as well as bokeh adjustments.
Because the blur filters are applied directly to the image pixels, rather than as a layer adjustment, I strongly recommend that you first duplicate the background layer of your image before applying any of these filters. If your image already contains multiple layers, select the topmost layer and merge the visible layers into a new additional layer by pressing  Command + Shift + Option + E  (Ctrl + Shift + Alt + E on Windows). Then go to Filter>Blur and choose either Field Blur, Iris Blur or Tilt-Shift.)  This will open the Blur Gallery.

Field Blur

Field Blur is the simplest of the three filters to use, but offers the least amount of direct control. When you select this option in the Filter menu, the image opens in a full size editing window. An active 'pin' is automatically placed in the center of the image, surrounded by an adjustment ring (the gray circle partially covered in white). At this point the entire image is blurred to the degree specified in the adjustment ring.
Field Blur opens with a 'pin' placed in the center of the image surrounded by an adjustment ring that applies a  blur to the entire image.
With your cursor on or near the adjustment ring you can drag your mouse along the ring's edge to adjust the blur amount. You'll see the blur value update (an example of of CS6's 'rich cursor' feature) as you move the mouse. Alternatively you can use the slider in the Field Blur panel. 
OK, so we've made the entire image blurry. Big deal. The fun starts as you add additional pins to the image. Move your cursor away from the adjustment ring and you’ll see the cursor now appears as a small pushpin with an plus sign alongside it. In this 'add pin' mode, simply click to place a new blur control so that you can specify a different  blur intensity at that image location. A blur setting of 0 prevents any blur from taking place, protecting or masking out that area of the image.
Place two pins on a single image and Photoshop creates a linear gradient that makes a smooth transition between the effects of each pin. Place three or more pins and Photoshop then constrains the effect of each pin to the image area in its immediate vicinity. You can place as many pins as you like on an image.
You can apply as many pins, at varied settings as needed to apply blur to some areas of the image while protecting areas you wish to remain sharp.
Press and hold the M key to see the actual blur mask. Areas in white have a blur applied to them while areas in black have been protected. Shades of gray represent partially affected regions.
You can see that I've added a lot of pins in this example in order to restrict the blur effects to specific areas of the image. Note that each pin can be set to its own blur value, so the real value of Filed Blur comes if you're prepared to place and adjust multiple points on an image, which admittedly can take time to get the precise results you're after.
Here's the original image. The background is distracting.
Using the Field Blur I was able to slightly blur the background, drawing attention to the dog chasing the kite.

I was able to create a gradual transition in the amount of blur on the sand by applying several pins at different intensities, but this also required numerous pins to protect the dog.

Images like this one with complex elements like the 'flying' fur of the dog call up some limitations of the Field Blur tool. If you look closely you'll find areas around the edges of the subject that will require some clean-up work with Photoshop's clone/healing tools.
While this may seem like an awful lot of work, one of the things I like best about Field Blur is that it tends to lead to more realistic results with natural-looking transitions that looks as if they could have actually been done in-camera. The Iris Blur filter, which we'll examine on the following page, can produce results with less effort. Yet it is very easy to produce an overdone result that any experienced photographer will recognize as a post processing edit.
