Photo editing

Once you have shot or chosen a photo, you may need to change its size or other elements to suit your needs.


Editing tips

Proportions and contour

Be careful when editing a photo to retain its quality. Stretching and bad contour are common examples of mistakes made during the edit.

Stretching - the objects in the photo are not proportionally correct. The width of the photo has been changed without adapting the height ratio.

Bad contour - the outline of the object (person and books) has been poorly selected and doesn't blend well with the background.


Image resolution

For print publications a high resolution image (300dpi) is best. For the web low resolution (72dpi) is preferred. The image library (staff access only) labels images as appropriate for print or web use.

too low resolution correct resolution

This image is 60dpi and features too much jpeg compression, making it appear pixelated and distorted. 

This image is the correct web resolution of 72dpi and appears clear.


Photographic collage or montage

Collage and montage are examples of digital photo manipulation. Photographic collaged or montaged imagery is not part of UniSA's photographic style.

Collage - a number of images have been combined into a total image that looks messy.

Montage - this technique merges multiple shots in a variety of ways.


Editing software

Adobe Photoshop is probably the best photo editing software available. However it is very expensive so you may not have it licensed to your PC.

Software help - Images for the Web is a guide to using Paint.NET, an excellent free application developed by Washington State University. You will need to log a Help Desk Service Call and request the installation of Paint.NET on your PC or, if you have administrator access, you can download Paint.NET and install it yourself.
