image editing, resolution, print
-
hi guys ,
recently, i just combined a few pictures into a photo using a picture editing tool - photoscape. i transfered it into a thumbdrive, but when i developed it at the shop , i found out that the photo was blur.
Should i change the resoultion of the picture before printing?
Or should i convert the format of the pictures?
I need reply to this urgently. thanks :)

Blurriness can be due to many things. Resolution of picture, printer and more. Though lower resolutions do help in reducing blurriness. Did you make any of the images larger when combining? Stretching the images will cause blurriness, no doubt about that.

i dont think i have make any of the images larger. anyway, the size of the picture i printed out was 4R size. so shouldn't be too big.

You mean higher resolutions? Lower resolutions = lesser details.
EDIT: That's assuming that the physical size of the image is a constant. In fact, the resolution of an image do not affect its quality at all, because it's just an instruction to whatever that is printing the image about how many dots should fill an inch. It's the number of dots (pixels) in an image that counts (and if you ask a professional photographer, they'll say it's the lens that count

On screen, images are displayed at 72 DPI (dots per inch) where as on print, it's typically 300 - 600 DPI. That means, a picture that has 720 dots in width will cover 10 inches across your monitor but only 2.4 inches on paper (at 300 DPI). And if you try to stretch that, you'll get a blurry print.
So, as a rule of thumb, if you want to print a quality picture, make sure it's clear and is at least 4 times bigger (in width and height, not area) than the actual print size on screen.
One more thing, make sure you save your image in a lossless format (eg. BMP, PNG-24, TIFF). If you save it in JPEG or GIF, the image's gonna lose details and that wouldn't be something you want to happen.
