adjusting exposure question - PP
Quick question, I'm editing my photos in CS2,.

When my images are underexposed, do I adjust the Gamma in levels, the exposure bar or the brightness bar to correct for the underexposure?.

Does anyone else feel confused about the use of these three adjustments?.

Thanks in advance...

This is one of the reasons Adobe invented Photoshop Elements..

There you have lots of choices, too, but at least the instruction book is semiunderstandable..

But, leaving that aside, what happens when you adjust in each of these methods?.

It actually is OK to look at the screen and use your brain to make an assessment. In photography, there's no reason to look for a rule when your eyes work just fine..

The otehr day I fixed someone's picture by duplicating the image, puttingthe sedond layer on top of the first. Then I lightened the whole second layer. Then I erased the new layer's now lighter sky, so the new-lighter foreground stayed, and the old, darker, sky became visible..

So, none of the rules applied..

IS GAMMA THE RIGHT PS TOOL?.

Are you working with an HDR converted image in PS? If not, I'd stick with some of the other tools. Playing around with gamma in the Exposure tool has always caused me more problems than it solved. I'm worikng with CS3, but I'm guessing 2 is similar in the basic tools; although I'm told Brightness/Contrast sucks in PS2 while they've really gotten it working right in 3..

I'd stick with Curves like Match Color and Hue/Saturation and then go into Curves and work the RGB levels.AzArtGuy..

Analogy. You want to see things from above. You climb a tree. You climb the stairs to the top of the building. You take the elevator. You climb a hill.

You take cable transportation. You use a helicopter. You use a plane. You buy a Yves-Bertrand album. You buy satelite images..

Do you feel confused by all these options?.

Back to your question. Use whatever method you feel happy with. When you are no longer happy, learn another one. Personally, I'd use curves, which are not in your list. Plus other tricks, as the image needs..

Thanks in advance..

You are welcome...

Yep, we're all confused..

Gamma correction is something I avoid like the plague - it's not really suited to digital images ( it's really intended for analogue video signals ). It's not very refined or subtle..

I would say, however, that adjusting curves or levels is the way to go. It takes practice to get a feel, an instinct, for what works ( with curves ) and there are no hard and fast rules. I would generally try 'auto levels' and then either tweak the result with curves or simply use curves instead..

And having said that, one reason I use LightZone is because it doesn't use any of these. It uses a zonal system which I find more intuitive. From anecdotal evidence people either love it or hate it..

There is no absolute rule. Use whatever works to produce the final image you like the look of. I usually end up with more than one tonal alteration..

If you don't know what you're doing with Photoshop, it will be very frustrating. I know from experience..

In the end I went and bought a book (Photoshop in Easy Steps was the easiest and cheapest book I could find), and tried everything in the book. I also looked at tutorials on websites like Luminous Landscape. Eventually I figured out a way to get what I wanted. There are plenty of free podcasts (both audio and video) on the subject too..

In the meantime, while you are learning, just make sure you only work on duplicates of important photos, because in a year or so, you'll want to go back and work on photos again as your skills improve..
