Exposure adjustments using Blend Modes

To make Exposure adjustments using Blend Modes you first make a layer. When you make a duplicate or copy layer it opens in Normal Mode and has an Opacity of 100% in the layers pallet. Normal Mode does not change the appearance of the image. In the Layers Pallet Layer 1 automatically becomes an active layer and the Blend Modes become active and you are able to change the Blend Mode and Opacity of this layer.

I find blend modes the most effective way to make exposure adjustments. In the Layers Pallet to the right of the word normal lick on the arrows and a menu pops up, scroll through each Blend Mode in the menu to see how they affect the image. The two I use to affect exposure are Screen and Multiply.

I selected Screen mode to lighten the image, this will usually make the image to light but by clicking on the arrow next to 100% and moving the slider to 25% for this images, I lighten the image to the exposure I want.

I selected Multiply mode to darken the image, this will usually make the image to dark but by clicking on the arrow next to 100% and moving the slider to 25% for this images I darken the image to the exposure I wanted.

Exposure Adjustments in Camera Raw using the Exposure slider

If your exposure is over or under exposed you can make adjustments with the exposure slider in Camera Raw. I had already worked with this image and saved it as a tif. In Photoshop if you go to FileOpen As  the image can be opened in Camera Raw like the original raw image.

I had already processed this image. In order to demonstrate how to make an exposure composition I have moved the exposure slider the left to -0.50 which  under exposes the image and makes the image darker. If I had moved the exposure slider to the right to +0.50 it would make the image lighter and over exposed the image.

I moved the exposure to the left +0.50 stop to 0 to lighten the image to the exposure I liked best. This is also the exposure that I captured in the Camera. I try to expose and crop the image in the Camera to create the best possible file. My goal as a photographer is to use Photoshop to make a good image better not make a poor image usable. In Photoshop Elements 11 and CS6 you can make adjustments up to 5 stops  plus or minus but I find that if you have over of under exposed the image by more than 2 stops your recovery efforts will brings poor results.
