Re: Image Resizing

When I do presentations I always try and find out what the projector native resolution is and resize appropriately

Having said that it also depends on how bothered I can be once it is down below a certain size the difference you will see on screen is limited

Therefore my usual 4/3 ratio is 1600x1200 (UXGA) and my default widescreen size is 1920x1200 (WUXGA)

Below that I will let the software/projector interpolate not expecting anyone to see much difference

Having said that when I recently had some of my pictures sown on a 4K projector with about a 100ft throw resulting in pictures about 15ft across and I did put in 4096x2160 (or that height on 4/3 format pictures) and they looked totally fabulous until the adaptor failed and we had to drop back to standard HD :-(

small point for you - not being involved with camera clubs I had never heard of PAGB so googled it and I found this on the Lancashire & Cheshire Photographic Union pages...

You are probably aware that the PAGB have taken a decision to adopt a new standard resolution of 1600pixel by 1200 pixel for images entered into competition from July 2017
seems they are falling in line with me :-)
