One of the most recent design jobs I did was a full colour A4 flyer for a crane truck company. They had an existing logo which they wanted to feature in the header of the flyer, though it had to be re-created as they couldn’t supply the logo file. Then they had a whole heap of photos they wanted to include on a single page layout.
Some of the photos were quite dark, taken early in the morning I suspect, so each photo had to be individually treated in Photoshop to try and get a reasonably consistent level of lighting throughout the page. It should be noted though that if a photo is really dark, too much lightening can affect the quality of the image. Ideally you would have plenty of light on the raw image to begin with in most cases.
A little bit of Photoshop work was also required on the bottom image to remove signage from a company they no longer work with. See if you can pick where that was altered..
