What image size/resolution should I change my 6 megapixel image to for uploading to get printed to 4x6?

Question

Because a three megabyte image takes for ever to upload, what should I change it to?

Answer 1

300 pixels per inch (ppi) works well for any printer. That's also about as much detail as our eyes can see without magnification.

So for whatever size print you want, just multiply 300 times the number of inches.

300 x 4 in. = 1200 pixels
300 x 6 in. = 1800 pixels

For 4x6's resize to 1200 x 1600 pixels, and save with high quality jpeg. (Don't use low quality (small file size) jpeg. It will lose quality permanently.)

File size will be around 1.5 meg.

Good luck

Answer 2

Theoretically, sure. even nonetheless, determination isn't completely based on what number pixels a digicam has. sure, pixels are significant, yet different components such via fact the lens, sensor length, and image processing all play a contributing place to determination. So as an occasion, in case you evaluate a 6 megapixel DSLR with a 7 megapixel factor-and-shoot, the DSLR digicam will nevertheless have greater determination via fact of its greater effective lens and larger sensor.

Answer 3

For printing pictures you really want to use as many megapixels as possible to not loose any quality. The disadvantage of digital imagery is the loss of quality from increasing, or even decreasing, the size of a picture.

Answer 4

Size it at 6" x 4" at 300dpi and convert it to JPEG (*.jpg)
