Creative Photo-editing
Creative Photo-Editing gives the power to do everything from removing a babies chicken pox at a wedding (like I had to do recently, bless her), to glowing someone's complexion, improving the background and presenting several photographs together in a creative way. Here's some examples:
Photo-Merge
Using several photographs merged together to create one.

Tryptich
Using three related photos, or cut out crops from a larger photo and put into the three or more windows. This can create quite a strong effect with photos that on their own may not be strong enough for display.
Muted Colours
One step short of going to full black and white is to leave only the faintest hint of colour.
Tryptich with large border and Monogram
As a normal tryptich but set high with some writing underneath. This can look quite artistic for a wall hanging.
Colour on Monochrome
Sometimes called "spot colour", most of the photo in black and white, but part of it requiring attention is in colour. This is very good at letting something small be very noticeable.
Vignette
The centre of the photo is feathered into either a blackend or whitened border. This can add romance or drama to a photo.

MontageOften events have so much happening that it is difficult to sum them up in a single photo. This is where I find the Montage particularly helpful. I take a selection of the shots from the day that I think have impact, show something about the day, and work well with the others I have chosen to form a single photo that can be printed off as a 10x8 (for example) and be a great record of the day.
