Before you start working on your image remember you should never modify original images. Always either work on a copy or copy the image to a new layer and keep it locked. You can guarantee that at some stage you will make a mistake. If you have the original image or a locked layer you can easily start again.
Images are often a responsibility that is overlooked by the design team. Image quality has many meanings but here we mean that the image is crisp and that contrast, levels and colours are as good as they can be. Often the brightness or contrast means that the image is unusable. In a few cases the image cannot be improved but in most if not all there is a simple trick in Photoshop to rectify problem.
Photoshop comes with a number of Auto correction features that can fix most common problems. Unless I am 100% happy with images I run most images through these to see if they can be improved. Open an image in Photoshop and then go to Image > Adjustments. You will see three Auto correction options:
The Auto Levels command automatically adjusts the black point and white point in an image. Basically this increases the contrast of the image in proportion to the colour channels in the picture.
This automatically adjusts the contrast without looking at the colour channels
This searches the images and corrects common colour issues. It identifies shadows midtones and highlights, neutralising midtones and cliping shadows and highlights. It can have the effect of washing an image out but generally it does a good job
You can see in the following example that good results can be achieved using these tools.
The Auto-correction tools also allow you to fine tune what they have done. Once you have completed the auto-correction you can add an adjustment layer. Go to Layer > New Adjustment Layer. You can choose to target many different aspects of the image. Which one(s) you choose to use will depend on the image has come out.
Photoshop offers you hundereds of ways to improve the quality of images. Unless I’m doing some artworking I normally find that the Auto correction tools and a few adjustment layers will do the trick. If not you can explore the many options available under Image > Adjustments. The options are too many to list here but they are worth exploring!
