-or color correcting by the numbers -or the 90% color correction method
Shooting:
YOU should already have these shot from the assignment Shooting the Target
Shoot 2 sets of images using the Target (white, gray, black card, found in the back of the Kelby book)
•set 1 available light outdoors, do not use on camera flash, set appropriate white balance not auto WB
•set 2 available light indoors use a tripod if necessary, this could be photographed in the studio if you have the experience, do not use on camera flash, set appropriate white balance not auto WB
Remember:
1) do not have any reflection or glare on the card.
2) both image 1, with card, and image 2, without card, must be the exact same exposure.
3) set appropriate white balance not auto WB
4) shoot one image with card, and the second, same image without card.
5) do not shoot a lesser resolution for the card shot. This will effect the results
Photoshop:
•Download images to the computer
•Open Photoshop
•Open the two images, one with and one without the card
•Open the info panel, make sure it is visible
•Create an Adjustment Layer – Levels (DO NOT USE ADJUSTMENTS THAT ARE EMBEDDED INTO THE FILE. THIS IS A DESTRUCTIVE WORKFLOW. YOU WILL NOT HAVE OPTIONS IF YOU CHANGE YOUR MIND AS TO HOW SOMETHING SHOULD LOOK.••• USE ADJUSTMENT LAYERS)
•Click on the highlight eyedropper in the levels adjustment panel. It is now highlighted and active.
•In the image click on the white square (notice a color change in the image?)
(You are setting a known neutral value to the white. This will help to rid any color casts from lighting when the image was shot)
•Click on the Midtone eyedropper or the Shadow eyedropper in the levels adjustment panel. It is now highlighted and active. (You will try both to see what looks better, remember, Command “Z”)
•In the image click on the gray square or black square. Experiment and see what looks better.
•Now you have a color neutralized image. Whites are whiter, colors are more saturated, and brightness and contrast are improved.
•If needed, you may want to drag the shadow slider to the right finding the point of black in the image.
(Sometimes all you need is the white eyedropper. Sometimes white and black. Sometimes only the midtone eyedropper. The purpose is to neutralize the color cast. This is the goal we are working towards with this project.) Experiment and play. Remember not to lose your shadow or highlight detail. Many times the black eyedropper will alter the contrast too greatly.
Your white eye dropper should be set R245, G245, B245
Your midtone eye dropper should be set R133, G133, B133
Your black eye dropper should be set R7, G7, B7
-Have both images viewable on your monitor. (untab them, click and hold on one of the tabs and drag them apart in the window)
•If you shot many images under the same lighting conditions, one adjustment will work for all. Keep dragging the Adjustment Layer to all files shot under the same conditions.
-Drag the Levels Adjustment layer to the Image without the card.
In the Layers Panel, Click, Hold, Drag the layer to the image without the correction.
Now your correction is in the file without the card
Save the corrected non card file.
Do not save the card corrected file
upload the non corrected card file and the corrected non card file to flickr
•Size your before correcting, and after correcting images to
800px on the longest side, 72ppi (size your images after you correct them)
Save your layered .psd or tiff files,
then Save As for your .jpg.
You will have your full camera sized layered images as well as your flattened smaller .jpgs for online
Save As .jpg for flickr
