Changing the Photoshop CC Crop Tool to Work as Before

With the release of Photoshop CC, Adobe made some changes to the crop tool so it acts like the version in Lightroom and Adobe Camera Raw (ACR). In all three programs, when you select the crop tool, the bounding box is already placed around the entire image; you do not have to drag a box manually. So you can start adjusting the sides as soon as you select the crop tool.


The crop tool in Photoshop CC, Lightroom and Camera Raw crops to a particular ratio or proportion for the image (e.g., a square, a panorama or a rectangle), not to specific dimensions and resolution. In addition, the cropping box displays reference lines, such as a Rule of Thirds or a traditional grid, to help strengthen composition during the cropping process. And no pixels are permanently discarded when you use the crop tool in Photoshop CC, Lightroom or Camera Raw.

All these features are intended to speed the cropping process and provide non-destructive editing because you can back out of a cropping mistake.

But what if you like the way the crop tool used to work? You want to specify a width, height and resolution. You want to draw your own cropping box and you don't need any extra lines showing to distract you. Finally, you want to delete the extra image areas; that's why you are cropping to begin with! How can you get the Photoshop CC crop tool to behave in the manner you're accustomed to?

Here's how to change the crop tool in Photoshop CC so it exhibits the old behavior. Choose the Crop tool. Press the Escape key to deactivate the tool.
  1. In the Options bar, click on the Ratio drop-down list and select W x H x Resolution.
  2. In the Options bar, click on the "grid" icon and from the drop-down menu choose "never show overlay".
  3. In the Options bar, click on the "gear" icon (next to the grid icon) and check the "use classic mode" box.
  4. In the Options bar, check the box to Delete Cropped Pixels.

New crop tool options for past behavior

You may want to save these choices as a Tool Preset so you can easily return to them if you have to reset Photoshop for some reason.
  1. At the far left end of the Crop Tool Options bar, click on the tool icon.
  2. Click the small "paper" icon for a new tool preset.
  3. Give the preset a name and click OK.

Now the Crop Tool in Photoshop CC works as it did in Photoshop CS6 and older.

Create Better Car Trail Photos with Photoshop Elements

I recently read a new book from colleagues Gabriel Biderman and Tim Cooper called Night Photography: From Snapshots to Great Shots (Peachpit Press, 2014). Along with fantastic advice about equipment, exposure and creative techniques for after the sun goes down, the book includes a last chapter with tips on processing your nocturnal images. There I read an easy way to improve the impact of car trail photos. While the directions use Lightroom and Photoshop, I discovered that with a minor change, I could create the same effect using Photoshop Elements. So for all my budget-minded friends, here's how to create the same effect using Elements 9 or newer.

Preparing the Photos

It's preferable to capture your night photos of car headlights and taillights in raw format and from a tripod. These two techniques provide you with several advantages:
  • Raw files capture more data and provide flexibility with white balance changes to fine-tune the color of your night shot.
  • A tripod is required for a sharp shot at the long exposure times necessary to record the lights of passing vehicles. 
  • Shooting from a tripod ensures your images will all line up when you combine them later in the Elements Editor.
Below you see the three photos I captured on a trip to Las Vegas, NV, several years ago. I was disappointed that there was not much traffic on the street the night I had access to a high vantage point. So even though my exposures lasted between 4 seconds (first two frames) and 10 seconds, there weren't enough cars passing to fill the roadway with lines of light. Fortunately, I didn't erase the frames from either my memory card or my hard drive. Now I have a way to improve them!

Before combining the frames, process all the pictures in Adobe Camera Raw (ACR) for the same white balance, sharpening, noise reduction, shadows, etc. The easiest way to do this in the Organizer is select all the pictures you want to combine, then click the Editor icon. This automatically starts Camera Raw and includes all your photos in a strip along the left side of the work area. Click the Select All button at the top of the strip and make any of your desired changes. However, do not do any cropping. You can crop after the images are combined.

I adjusted the White Balance of all three pictures to fluorescent (from tungsten) to clean up the colors away from the streets where the car trails were. When you are satisfied, click the Open Images button to bring the photos into the Editor.

Stacking the Photos

NOTE: To accomplish this step you need to have Photoshop Elements 9 or newer. In version 9, Adobe included the ability to add a layer mask to a pixel (image) layer. (Before this the only masks available were on adjustment layers.) You may want to use a mask to hide parts of some frames from the final composite.

In Elements 12, click the Enhance menu and choose PhotoMerge, PhotoMerge Panorama. (In Elements 11 and older, click the File menu and choose New, PhotoMerge Panorama.)

Start PhotoMerge Panoram

In the Panorama window, make the following choices:
  • For Layout select Auto
  • For Use select Files
  • Click Add Open Files
  • Check Blend Images Together 
  • Click OK
PhotoMerge Panorama choices
Elements combines all the images into one document and aligns the photos. When it has completed this processing, a new window appears, asking if you want to automatically fill in the edges of the panorama. Since you are stacking images, not stitching them together, click No.


Because I shot all three frames from a tripod, there is almost no misalignment between shots. So when Elements attempts to automatically match one image with the next, they end up stacked one on top of the other, just what I want. 

The new document has multiple layers, one for each file, and each has a layer mask. The top layer masks are black, hiding all the information from these photos and showing only the picture on the underlying Background layer. To reveal the additional car trails, you need to make a few easy changes.

Revealing Additional Car Trails

Follow these steps to reveal the car trails from the other two pictures:
  1. In the Layers panel, click on the top layer to select it.
  2. Click on the word "Normal" and change it to "Lighten."
    This is called a blend mode and instructs Elements to allow only the lightest parts of this image to show through to the layer below.
  3. Click on the mask (the black rectangle) to select it.
  4. Press Ctrl + I (Windows) or Cmd + I (Mac) to invert the mask color from black to white. (Or from the Filter menu, choose Adjustments, Invert).

Repeat these four steps for all the additional layers except the Background layer. Now all the car trails from each of the three photos are visible. If necessary or desired, use the Brush tool with black paint and paint on a mask to hide parts of the car trails from that layer. In this example, I did not do any painting in my example photo.

Top two layers set to Lighten
Layer masks inverted to white

Save this as a new document in Photoshop format to preserve the layers. If you want to crop or perform other adjustments to the combined photos, you may want to save a second copy as a TIFF file. Flatten the layers and then work in either the Elements Editor or open the TIFF file in Camera Raw for additional processing.

Sit back and admire your work when you are finished and share it with your friends!

Update: Repairing Pet Eye with Photoshop Elements 12

When Adobe released Photoshop Elements 12, they finally included a long-missing feature: the ability to automatically fix "pet eye"! This changes the Red-Eye Removal Tool from looking for red pixels to looking for the green, blue, or yellow discoloration found when our camera's flash reflects off our pet's eyes.

Before and after using the Pet Eye option of the Red Eye Removal Tool


Here's how to use this tool.
  • Open a photo of a favorite animal that has pet eye.
  • Select the Red-Eye Removal Tool. 
  • At the bottom of the screen, click the Tool Options button to reveal the settings for this tool. 
  • Check the "Pet-Eye" box.
  • Zoom in to 100% (View >Actual Pixels) on your pet's face.

  • Click on the discolored eye for repair. 
  • If you don't get the results you want, click the Undo button.
  • Then adjust the Pupil Radius and Darken sliders and try again. Slick!
Adjusting the sliders creates a better repair of the dog's left eye.

This tool worked great on the round eyes of the puppy but not so well on the "almond" shaped pupils of my cat's eyes. The tool changed the green to black but the shape of the repair didn't match the shape of the eyes. So for some images you may still need to repair pet eye manually. Read how in my earlier post.

The best way to deal with pet eye is to avoid it altogether by turning off your flash and raising the ISO setting as I did in the picture below.
