What is Exposure in Photoshop?
The Exposure slider is probably the least mystically named of the control sliders and unsurprisingly it allows you to adjust the exposure of your photo. Dragging to the right will lighten an image, while dragging to the left darkens it.
The Offset slider isn’t obviously named, but this control has greatest influence over the dark tones of photos. Sliding it to the right will lighten shadow areas, but you should take care as you’ll quickly see that images can start to look washed out as this is adjusted in this direction. Sliding to the left will darken your shadow areas and if you overdo this, you will start to see some unnatural color shifts occurring.
The Gamma slider has greatest effect over the mid tone range of your images, though the direction that you adjust the slider is counter intuitive. To darken the image, you need to slide it to the right and vice-versa to lighten it.
This is all for today. I hope that you enjoyed the tutorial.
