one could go for a very super detailed live traced conversion of the photographic image into a vector image, where even skin texture is vectorized, but that is gonna take a lot of computing power, give a huge file probably much larger in file size than the original rastor file and thus very unwieldly... you would still only have as much resolution as the original file has, possibly visibly sharper than a rastor resize, YMMV depending on how detailed the live trace was, and point a) of my earlier post would still apply...

sorry to bring up this thread but i wanna ask smth regarding resolution, i found a picture on the internet with resolution 811 x 1024. If i wanna blow it up into a poster, what would be the best size for it so that the poster will still turn out sharp
oh no i think i got it wrong, its dimensions is 811 pixels x 1024 pixels and the Horizontal resolution is 300 dpi and Vertical resolution is 300 dpi with bit dept of 24.
i dunno what size to blow up to, best if its bigger yet retain its sharpness. thanks
300dpi means 300pixels = 1 inch. 811pixels = 2.7inches. Just think for a moment how big can you blow up without losing detail.
At A5, image may still be "sharp", at A4 image will be soft and pixelated.
One way out of it is to use Photoshop and enlarge it at 10% increment each time followed by sharpening until you get to your desired size. That means you got to increase your longer edge by 4 times (3244pixels x 4096pixels) in order to print it in A4.
wow! okay, pretty confusing. dont worry i just intend for my personal collection, not for sale or anything
From experience, if you have a sharp picture at 200dpi at the given size, it should give you no issues when printing. Also it depends on the size you printing. Its not exactly necessary to have a 300 dpi A3 as its not meant to be look at 10cm. Of course if you are printing graphics or fine art, you may need the higher DPI.
i intend to print it around A2 size or above? possible?
Assuming viewing from optimal range. Its good. If you intend to view at 10cm, you will need twice the resolution lol
