hi all, i'm entering a photo contest and one of the requirements is that the picture has to be 300dpi. I use a Canon T3i (600D) and i'm pretty sure i have the resolution up at the highest and shoot at RAW+jpg. my pictures seem to be at 240dpi. can this camera go higher?

DPI is meaningless unless you are going to print?

Are there other requirements? Size, etc??

How did you determine that your images are 240 dpi? From the exif data?

Here are some links in understanding dpi and resolution.

if the picture is one of the ones selected, it will appear in a small calendar. there are other requirements which I have. it also said the picture needs to be 300dpi so it looks good at 5x7". i know 240dpi is more than enough for that, but I just don't want to get disqualified just cause of this dumb number. I got the 240dpi by right clicking on the image file->properties->details. as luck should have it though, the picture I might submit actually has 350dpi. not sure why that picture is at 350 and all the rest are at 240. can I do something to a 240dpi picture so it can be 300dpi?

That makes more sense. dpi only has meaning in relation to physcial dimensions.

At 300 dpi for a 5x7 image you need a final resolution of 1500x2100 (5x300 and 7x300). So if the 300 dpi, 5x7 is a hard requirement, this means you need to crop the image so that it has a 5x7 (or 7x5 depending on orientation) aspect ratio and perhaps also downsize so it's at 1500x2100 resolution if your are working from an image of higher resolution. To finish it off, change the dpi to 300. At this point, this is kind of meaningless, but since they require it you should do.

Hope you are starting to get the picture, pun intended!

If they are minimum requirements than higher resolutions with higher dpi would be OK.
