Having an interest in both presentations/slides and photography, I really like some of these images, there are certain elements that make an image usable in a presentation, IMO these are:
- must have a strong composition
- should have a logical space for text (with a solid background on this area)
- should be sharp
- should have low noise (digital noise common on low-spec cameras)
- abstract is OK, but mustn’t be too dominating/random
- must have contextual relevance to your message/story
- if you’re buying images the ability to re-use them in differing contexts maximises your value ;)
- should avoid too many strong colours (makes it harder to overlay a standard footer)
Basically, the images and content in your slides should add context and augment your messages, having pretty pictures for the sake of it adds nothing. I really like having a couple of words (or a quote) on the slides against a contextual backdrop of a visually pleasing (but relevant) image.
It works for me…
I have previously recommended a couple of books that have helped me with my presentation (and slideware) styles: http://www.mattgrovesblog.com/2009/12/presentations-5-rules.html
I strongly recommend looking at Duarte’s “5 rules” in PowerPoint 2010 - assuming it made it into RTM!!!
My personal favourites from the deck above are:
13 – strong composition (if a tad obvious) with space for text on a solid backgound
19 – good composition with space for text on a solid backgound
23 – usable in lots of contexts
70 – great image (having tried to capture water drops myself I can guarantee this image took time!)
68 – if moved off-center (easy as it’s a solid white background) this can be used in lots of ways
81 – used this myself as an Agenda slide! (just use the right font!)
95 – usable in lots of contexts
The ones I recommend avoiding:
38 – too predictable ;)
39 – too many clouds – there are better “blue sky with white fluffy clouds” images out there!
50 – I don’t see a message this could convey (happy to hear your thoughts)
61 – far too busy
71 – trite
72 – boring
76 – I don’t see a message this could convey (happy to hear your thoughts)
82 – rubbish
83 – un-usable
99 – I don’t like it, but I think @soulsailor might ;)
