Studio lighting can be quickly and easily dramatized by blending multiple layers.
Duplicate a layer with a subject by pressing Command – J (PC: Ctrl-J).
Desaturate the new layer, then adjust the Levels dialog (Command – L [PC: Ctrl-L]) to create a strong contrast.
Now, apply a Gaussian Blur (Filter>Blur>Gaussian Blur) to the new layer and set its blend mode to Overlay, which amplifies the saturation of the base colors, while retaining the tonal contrast of the new layer.
This effect can provide a strikingly more provocative sense of depth with very little effort.

Another way to lighten an image uses the Overlay screen mode. Here’s how: Open the image and click on the Create a New Layer icon at the bottom of the Layers panel. Press D to set the Foreground/Background colors to their default black/white, respectively, and then press Command-Delete (PC: Ctrl-Backspace) to fill the new layer with solid white. Change this layer’s blend mode to Overlay and you can then adjust the brightness of the image by changing the layer’s Opacity until it looks right to you.

When I’m shooting concert images, the lighting often changes quickly, and I end up with an image that’s just a little too dark. One of the simplest and most effective tricks to lighten an image is to use the Screen layer blend mode. Open the image, duplicate the Background layer by pressing Command-J (PC: Ctrl-J), and then change the blend mode of the new layer to Screen. Then simply adjust the Opacity of the new layer until it suits your needs.

When you have to place a number of images into your layout, save yourself some effort and first set up the graphic frame with particular specifications (Fit Proportionally, fit content to frame, fit frame to content, etc.). That way you won’t have to fidget as much to make the fit.
Drag out the frame to the desired size and proportion. Select Object > Fitting > Frame Fitting Options. Define the Crop Amount or the Reference Point (the point from which your sizes will emanate), and select Fitting > Fit Content Proportionally. Once you define one frame, Option/Alt-drag it to make a duplicate with the same parameters. Now when you Place (Command/Ctrl-D) an image, it will come into the frame with the predefined sizing.
