Hi All,

Sorry if the question has already asked. (another basic question)

I want to print my images taken from digital camera. When I downloaded it, the resolution was 72 pixels/inch. I took them to photo lab (for testing) and print few of them with standard size (4R), and the result was not that good.

I want to use photoshop to fix my images resolution. I did in this way.

I open file with 640 pixels x 480 pixels (original size)
Resolution 72 pixels/inch.
I copied the image and paste it to new higher resolution layer. (I use 200 pixels/inch)
Then I re-size the image to 1181 pixels x 886 pixels (or 15 cm x 11.25 cm for photo size)
I printed with hp psc 2110 printer and the image and it looks fine.
(But I don?t know if I take them to photo lab, the result will be the same or becomes dull as previously)

The question is,

Did I do the right step for change the resolution? Or is there any other way to do it?
I have heard to have the good resolution, we need to print the image and re-scan it.
But concerning of a huge number of images, it takes time to do that.


Thanks in advance and sorry for my poor English ;\ (Feel free to correct it anytime )

The problem is that the original resolution of the file is too low to make a good quality print at anything over about 2 or 3 inches wide. There just aren't enough pixels available to increase the print dimensions any further than that. You can try doing a resize, but you are asking photoshop to create pixels out of thin air using it's imagination, and photoshop doesn't imagine very well

The best thing to do is to increase the size that the photos are take at so you have more actual pixels to work with, if your camera won't take in a larger size than 640x480, you will have to resign yourself to smaller or blurrier prints, there isn't much else you can do about it.

You don't mention the format the camera is using, jpeg compression can have a serious effect on the image quality and is the default image format for most cameras. If you are able to select the format, a tiff image doesn't use compression, thus maintaining image integrity for post processing. Downside is obviously a lot less images per unit of memory.

Yes Toxin, I thought I used JPEG format, and somebody set up the quality to load more picture in the card (but, see the quality)

Thanks for the advice, you too MindBender to remind me this magic software also has limitation in some areas .

I have also message from Erik. and this time I realize that I posted it twice [shhh] without realizing it. He also gives me the alternatives way to improve quality of pixels resolution.

Here is the link.
