3D Photo Effect

by Mike, December 28, 2006 posted in Motion

In this tutorial I will show you how you can create an interesting 3-D effect for your photos by using gif animations. The result will look like this:

This is how it works:

principle

Step 1: Take a photo by looking through the view finder (the LCD screen won’t work well because it’s too inaccurate) with your right eye. Focus on a medium-range object and make sure you include a foreground object as well to get the maximum effect.

Step 2: This is the tricky part because you have to be really accurate. Take a photo by looking through the view finder with your left eye, while focusing on exactly the same point as in step 1 and also keeping exposure, focal lenght, vertical alignment and distance the same. You shouldn’t move the camera lens more than 2,5 inches horizontally (which equals the distance between your eyes) or else the effect will disappear. This may require some experimenting because different cameras have different view finder positions.

Step 3: Open Photoshop and create a new file by pressing Ctrl+N. For the example above I chose a size of 320×240 pixels but you can choose any size you want (however, the width/height ratio should be the same as your camera image ratio, i.e. 4:3, to make the placing process easier). Just keep in mind that animations with no frame delay like the one we are about to create run smoother and without any distortions only if they are small.

Now click on File > Place and select the image that you took in step 1. Place it in the newly created file by pressing the enter key.

Open the animations Window (Window > Animation) and duplicate the first frame by clicking on icon 1 that you can see in the picture below.

Place your other picture from step 2 in the newly created frame (File > Place > Enter).

In the layers window, click on the eye icon of the top layer so that it disappears like in the red circle below:

layers

Now you’re basically done. Test your animation by clicking the play icon (2) in the animations window. If the animation is too shaky, nudge one layer until you get a good result. You might also want to add some sharpness (Filter > Sharpen > Sharpen) or adjust the levels (Layer > New Adjustment Layer > Levels).

If there is no real 3-D effect, try step 1 and 2 again and experiment a bit with the horizontal distance of the two camera positions.

When you’re satisfied with the result, save your animation by clicking File > Save for web, choose GIF format and hit the save button.

Digital Cross-processing

by Mike, December 28, 2006 posted in Graphics

The term “cross-processing” sounds very technical and abstract. However, the technique to manipulate your images digitally as if they were cross-processed is very easy. But what is cross-processing actually?

Cross-processing, briefly, is a photographic technique where slide film (E6) is processed in the set of chemicals usually used to process print film (C41). The result is images with oddly skewed colors (usually with a cyan hue) and increased contrast and saturation because the high-contrast slides have to be enlarged on a paper which is actually intended for print films with less contrast.

Less common is cross-processing in the other direction–print film processed in slide film chemicals. The result you get then is lifeless images in subdued colors because the chemicals intended for slide films compress the lights on the already low-contrast print films. Moreover, you can never be sure what colors you will actually get.

The film material is extremely and irreversibly modified due to the cross-processing technique; therefore, the advantages of the digital cross-processing simulation are obvious. And the key for digital cross-processing is the modification of the curves.

Process a print film like a slide film (I will explain for Photoshop CS 2 here)

1. Open the picture you want to process.

2. Press Ctrl+M to open the curves window or click on Image > Adjustments > Curves.

3. Modify the curves for RGB and all channels (red, blue, green) as shown in the pictures below:

4. The curves here are only for a start, and you will probably have to re-adjust the curves (especially the standard-RGB curve) until you get a decent result. This technique is interesting especially for portraits.

Process a slide film like a print film

1. Basically, it’s the same technique as shown above. Open your image and adjust the curves like this:

2. Same for these curves: They are only a start; you will probably have to slightly tweak them to satisfy your needs.

3. Don’t worry about the brightness too much. Just play around with the curves and focus on the contrast and colors first. After finishing the curves, adjust the levels (Ctrl+L) and make your picture brighter by sliding the small right arrow below the histogram a bit to the left.

If you don’t want to mess with curves, try this script:

http://www.shanzcan.com/photoshop/Shanz_XP_2002.atn

Once you’ve saved to your disk, load ‘ShanzXPActions©2002′ into your Actions Palette. Use the Presets Manager or drag and drop it into the Actions Folder. There are 3 variations included in this folder; XP#1, XP#2, XP3. After running one of them on your image, you will have a layered file, and can further adjust your cross processed image, by changing the opacity of the layer(s), the blend mode, or just duplicate the crossprocessed layer for a more intense look. You may also have to add a ‘Curves or Adjustment Layer.’ ‘XP’ is my abreviation for ‘Cross Process’ and is NOT referring to the Operating system. This Action works on both Mac & PC.
