How to Size an Image
For best image quality it is recommended to match the Projectors resolution of 1024 x 768.
That doesn’t mean you have to resize your image exactly to that size as it would crop something off the image.
The standard photo format from an SLR is 3 x 2 so if you kept the width to 1024 the height would be 683, which is ok because it’s within 1024 x 768.
Probably the easiest way to do this is to first do all your editing/colour correction etc. Crop the image if you need to for composition purposes but with all the crop tool boxes cleared.
Then go to image/image size and make sure the 'resample image' box is ticked.
For Landscape format
Type 1024 (pixels) in the width box at the very top, the height will change on it’s own and should be no more than 768,click ok. If the height goes more than 768 then type 768 in the height box and the width should then go less than 1024.
For Portrait format
As above, but type 768 in the height box, the width will again change on it’s own and should be no more than 1024 click ok.
If you have a squarish type shot then you will have to try either 1024 for the width or 768 for the height but keep within the max size of 1024 x 768. So you could end up with something like 908 x 768 which is ok.
When you have resized the image go to file/save for web, choose jpeg, set the slider to 100% and save. You should end up with an image something like 300k to 1.5 mb (approx)
If you save your original images in Adobe (1998) colourspace and not sRGB then you may find the image loses colour and contrast and looks flat. All you need to do is convert the image to sRGB.
You can do this at anytime before you save for web. Go to edit/convert to profile and choose sRGB, not e-sRGB, click ok.
