Changing the temperature of a photo in Photoshop
Written: October 25th, 2003 at 07:28 PM by Ken Chevy
This is for those of you that (like me) are just learning how to use Photoshop (and other versions I would suppose). I have found that for me, if someone were to show me, I seem to be able to grasp how to do something easier than reading or being told how to do it. And for those of you who are gurus at Photoshop, if you see someway I can make the following easier/quicker, PLEASE pass that info on to all of us! Thank you.
I have only been using Photoshop a few months and don't know how to use it very well yet. I am learning a lot from reading what others say how they do it.
Many already know how easy it is to mask/and or/use layers to put different exposures together to make a more 'pleasing' picture. Many ALSO don't know the first step on how to do it. This small article is how I do it (sometimes... sometimes not, I am ALWAYS experimenting, trying to learn, you have a better way, tell me.)
We shoot Canon, Ani uses a D60 and I use a 10D. We shoot in RAW mode. Took me a while to figure THAT out, took me a while to figure out we MUST shoot brackets too. So usually we will shoot 2 stops under, 1 stop under and 1 normal (to the camera) exposure.
For this article I didn't use my bracketed exposures, I use the same CRW file for all three exposures to show how the temperature of a CRW file can be changed when pulling it into Photoshop.
2. For this 'MrChevy Show & Tell' I chose a Canon CRW (RAW) shot that was at a Temperature of 4000. Notice the size and resolution I use, also AdobeRGB 1998.
These screen shots are of the way I use Adobe Camera Raw (i.e. The Adobe ACR plug-in) to change the Temperature of the picture while pulling it into Photoshop. The ACR plug-in in a seamless interface to Photoshop, just click on a .CRW file and ACR opens. For me, the ACR download was well worth the money. They have included it in Photoshop CS (Photoshophttp://www.photography-on-the.net/forum/images/smilies/icon_cool.gif.

3. I 'process' the first copy I will use of it (CRW_1002.CRW) at a Temperature of 2600 another copy at 5200, and another copy at 15000.
Then in Photoshop I put (after changing them all to 8 bit under IMAGE/MODE, I could have just processed them at 8 bit and saved doing this step) the 5200 on the 15000, then the 2600 on top of that, lining them up. (This shot doesn't show them lined up yet, line them up as you move them over, I left them un-lined up for demonstration purposes only).

4. After lining them up, I set the eraser to 50% opacity and erase the bottom part of 2600, and then I go to the 5200 and erase what I want to remove of it. Notice how they look in the layers on the right side of the screen shot, you click between the layers to work on each layer.

5. When you like the way it looks, crop it, in this case, putting the rock off to the left side.

6. Do a small amount of levels on it to give the colors some POP.

7. Now we need to resize it for displaying it on the web.

8. I change the width to 800.

9. Convert the profile to sRGB for displaying on the www. Then I 'Save for web' at about 150kb size (for this picture it was at 90 quality to get it down to the 150kb size).

That is how this one was done:

Hopefully the screenshots will help you understand how I did it.
Added 04/16/05 This really doesn't show any mask work, it is just done with layers, masking would be easy to do too. But, there are a million (or more) ways to do the same thing in Photoshop it seems! Experiment. Have you ever thought of doing this to a photo? Experiment!! You can dramatically improve some so-so shots into beatiful ones.
Comments welcome.
