This question already has an answer here:
I am a novice when it comes to photography. But I have a picture that I would love to submit to a photo comp. Their specifications are: have suitable resolution to be printed between 596mm x 422mm (A2) and 841mm (w) x 1189mm (h) (A0) I tried to increase the resolution on photoshop and ended up with these numbers: Image size 1.84 M - With 644 pixels - height 1000 pixels - resolution 300 pixel an inch
Could any let me know if these dimensions are acceptable?
