Wedding Green Cast Automated Corection : Automated Correction Exercise These images were professionally shot on assignment at a wedding. All have a green cast. There are approximately 400 such images, so it is not feasible to correct each one individually. Instead, we need some type of automated routine that can be applied to all. It is a live job; the photographer is hoping to get something useful from our group. The photographer sent me a DVD with 101 raw images for the purposes of the exercise. Some were badly underexposed and, in my opinion, need t o be handled separately from the others. I chose five that I think are typical of the set. If you choose to participate, you must come up with a single routine that will be applied to each of these images--no image-specific variations are allowed. Obviously, the results will not be as good as if you were permitted to work on each image separately. For example, image 0002 is clearly pinker than the rest, so it probably won't take your automated correction as well as we'd like. You have three potential starting points to choose from. The first requires a download; the second two can be grabbed right here on the current page. 1) The raw files are provided for download (as a single 55 mb zip file) here. If you cannot or do not wish to open them in a raw module, you can choose from one of the other two options, grabbing the appropriate five images from the current page. 2) Using Canon's proprietary package, I have batch-opened the images without any correction at all. These files are labeled ACT Uncorrected. 3) Using the same module, I also acquired the five images with a 15-second correction to bring them closer to the desired result. This may make them easier to finalize afterward, or it may not. These are the ACT Adjusted files. The mission is to produce the best possible set of five images using only a single correction method that does not vary in any way between images. It can involve corrections in a raw module, as a Photoshop Action, or both. RULES: 1. The desired output is 1024 x 1536 pixel JPEGs, with sRGB profile embedded. 2. Because some may be using high-resolution raw as a start and others low-resolution JPEGs, it should be agreed that we will not consider excessive noise to be a defect. If the files were acquired at the proper resolution there would be no problem. 3. You must provide us with the steps that you took to create the image. If you are using Photoshop CS2 only, then copies of the .xmp file and/or the Action that you wrote will suffice. If you are using something else, then we need a text description of what the steps were. As a courtesy to those who do not have the program, please indicate why (if you know) these steps could not have been duplicated in Photoshop CS2. It would be helpful if you would add screen grabs from these applications showing the steps you took. 4. Post you results and screenshots here with approproate captions. The ACT moderators will provide the instructions by private mail. Dan Margulis
