So as a filler post this week I wanted to further go over a couple of other * beginner * tips on how to lighten or darken your photos. This will be a short post and really easy. But I just HAD to post SOMETHING! Ha!
So probably one of the most popular ways to lighten or darken a shot is done with duplicating the photo layer and changing the blend modes. To lighten you would choose screen blend mode and then play with the opacity of the top photo layer and you can always add a layer mask and do some masking if needed. And to darken a shot, instead of using Screen as your blend mode, you would choose Multiply. This is a great method and can be very successful at saving shots that didn't turn out right SOOC, or you want a different affect. The drawback with this method is it makes your file sizes larger.
Here are a screen shots of the Screen & Multiply blend modes. I didn't do before/after pics because I can't tell the colors without my calibrator. So for now, it's screenshots only!
This shot SOOC was underexposed. I upped the exposure a tad in ACR, but not too much so I could show you the duplicate photo screen method.
