We received a question about lighting techniques when you plan to use Exposure in your post processing workflow. The blog article can be found here. This did, however, bring up another interesting question. You can find the original support article here.
How do I increase the exposure of my image without an exposure slider, like the ones in Adobe Camera Raw (ACR) and Lightroom?
In Exposure 4, you can use the Midtones slider on the Tone tab. This is a great way to increase the brightness of your image without clipping your highlights or shadows.
Here is an example of an underexposed image.
Using the exposure slider in ACR. Setting was increased to +1.50.
Using the Midtones slider in Exposure. Setting was +84 Midtone.
There are multiple presets on the tone tab that can handle common adjustments like this. Though, some minor tweaks may need to be made to get the exact effect you are after.
