Frequently Asked Questions...
How big can my image be printed before it looks grainy?
How do you know if an image can be enlarged to a poster size, for example, A1 or A0 size. I have a few images that I'd like to have enlarged, but I don't know if the image is crisp enough.
Does it depend on the number of pixels? How do I tell that from looking at the file?
AND, if I TAKE a photo with this in mind, how can I ensure it's good enough quality to get enlarged later?
Answer:
The more pixels you have, the better quality the picture and therefore the larger you can have the print without it looking grainy.
Here's a rough guide:
5 MP = 2592 x 1944 pixels
High Quality: 10 x 13 inches
Acceptable Quality: 13 x 19 inches
4 MP = 2272 x 1704 pixels
High Quality: 9 x 12 inches
Acceptable Quality: 12 x 16 inches
3 MP = 2048 x 1536 pixels
High Quality: 8 x 10 inches
Acceptable Quality: 10 x 13 inches
2 MP = 1600 x 1200 pixels
High Quality: 4 x 6 inches, 5 x 7 inches
Acceptable Quality: 8 x 10 inches
And so on.....
You should be able to tell the amount of pixels in the file saved on your computer.
You would just about squeeze a good quality A2 print from a 12MP camera... don't forget though, when viewing a larger picture you generally stand back, therefore any graininess is much less noticable.
Hope this has helped
