Outstanding job, Lesgainous. Easy to follow, well organized, and informative. I especially like the adherence to the rules of formal writing. An impressive piece of work!

Thanks, Laurie! I do write quite a bit of technical documentation in my profession, so I just do what I know best. In fact, I had to cut some things out to fit the DPC environment, as well as to not make it "boring". LOL!

Very nice, well done.

Not boring and very informative and very clearly written! And illustrations always help!!

Thank you for your efforts. I can't even imagine how long that must have taken.

I always love learning new things.

Anyone know if Photoshop 7 has the capability to do this? I had a jpeg that I saved as a tiff, and it is only giving me the 8 and 16, not the 32-bit option. It's not grayed out, it just isn't on the menu. Does this mean I can't do this?

I have Photoshop 8, and have the same question. I do not have the 32 bit option. Does anyone know why?

It was introduced with CS2 (v 9.0) I believe.

Great tutorial, Les. :D

Does anyone know a way to do anything similar in PSP?

Is this within regulation for Basic Editing here?

i had another approach on emulation the HDR effect, as you can see from the pic above. and it worked very well, i think, i compared it the method by processing a picture with my method and via HDR , the result were very similar. of course tone mapping with photomatix is a 2 step process, emulating with my method is 30-60 min process.

This is very nice, I quite like the effect. Would you care to elaborate on your method??

I often look through the Tutorials and I gotta say this is an excellent Tutorial! Thank you very much for posting it!

It took me a couple of plays to get used to it but I use it most of the time now!

Aw...shucks! Thank you very much. With the company of the other great "regular" contributors to the tutorial section, I am very flattered.

I have wanted to learn and develop this technique for some time, and this tutorial was absolutely stellar in guiding me through a process that has terrified me up 'til this point. I used in on an image that I really was at a loss to get the result that I wanted any other way.

Thanks so much for helping me acquire this powerful tool for my repertoire!

TIP: To aid in tonal curve adjustment, move your cursor to an area of an image and click-and-hold (drag) across that area. While dragging across the area, the cursor (pointer) turns into a pen icon. Also, while dragging, notice the small square on the tonal curve line that is moving in conjunction to your dragging. To adjust the tones and contrast in the area of the image where you were dragging, click on the curve in the position where the square appeared and adjust accordingly.


Okay, I have PhotoShop CS2 and I don't see this when I click and drag on the picture. What am I doing wrong?

You have the curves dialogue box open, right? When you click and drag on the image, a small square will slide up and down the line in the curves box to show the value of the area over which your cursor is passing.

Here's another way to do this, which I didn't include in the tutorial...

With the Curves dialog open, hold down the Ctrl key down (Command key on a Mac) and click on a part of the image. You will notice a small black square on the tonal curve line. You can let go of the Ctrl (or Command) key. Now use your keyboard's up or down arrow to raise or lower (respectively) that point on the curve.

I use this procedure in CS3, but could someone verify that it works in CS2?

Nice trick! I don't have CS2, but it works in PS7, so I'd assume it would have carried over.

Many thanks for this helpful and extremely well-written tutorial. Alas, the Ctrl/Cmd click maneuver in Curves does not work in CS2--another reason to upgrade.

It works in CS2. Might be the Alt key, but it defintely works as I use it all the time.
