A publication designer should be able to make a range of adjustments to your images to ensure the best presentation. This can be done using specialised image editing software such as Adobe Photoshop.
Image adjustments can include brightening or darkening; reducing or increasing contrast; correcting exposure or white light balance; adjusting shadows and highlights; shifting colour balance, hue or saturation; changing colour mode between RGB, CMYK or greyscale; rotating, zooming, flipping or cropping; editing; extending or removing backgrounds; and deleting unwanted detail.
However, a designer cannot work with poor-quality images; the photograph must be of decent quality, high resolution and clearly focused to start with.
