Basic question - with my G6 if I want to crop a shot and still have it print 8X10 what is the best way to go about it. So for example, I have a pic of my parents dog in an 8X10 300 DPI format. I want to just crop the dogs face and still have it print 8X10 but every time I do that it shows that it is for example 5X5.

With my zoom browser software that came with my G2. When croping, the new pictuer size is being displayed in the botom right.

I think there is a solution whith a photo software it is called resampling, and that is basicly just adding pixels to a photo but I suggest doing it 10% at a time so you loose as less detail as you can, but adding pixels just increases the file size and not the quality so the next time you take a shot take more than one and diferent kind of shots ( also try allways to take vertical and horisontal)...this is about resampling from this website...http://graphicssoft.ab​out.com/ (external link)

Q. How do I change the print size of a digital photo?

A.

Many digital photos will open into your photo editing software with a resolution of 72 ppi. This is either because your digital camera does not store resolution information when it saves the photo, or the software you are using can't read the embedded resolution information. Even if your software does read the resolution information, the embedded resolution may not be what you really want.


Fortunately we can change the print size of digital photos... usually with little or no loss in quality. To do this, look in your photo editing software for an "Image Size," "Resize," "Print Size," or "Resample" command. When you use this command you will be presented with a dialog box where you can change pixel dimensions, print size, and resolution (ppi).

When you want to change print size without loss in quality, you should look for a "resample" option in this dialog box and make sure it is disabled.

When you want to change the print size without stretching or distortion, look for a "constrain proportions" or "keep aspect ratio" option and make sure it is enabled. (With this enabled, you may not be able to get the exact dimensions you need. See the glossary page on aspect ratio (external link) for more information.)

When the resample option is disabled and the constrain proportions option is enabled, changing resolution will alter the print size and print size will alter the resolution (ppi). The ppi will get smaller as the print size increases. If you know what size you want to print, enter the dimensions for the print size.

  • If the ppi changes to 140 or less, you will get a low quality print at that size.
  • If the ppi changes to 141-200, you will get an acceptable quality print at that size.
  • If the ppi changes to 201 or higher, you will get a high quality print at that size.
If you do not have enough pixels to get an acceptable or high quality print, you will need to add pixels through resampling. Adding pixels, however, does not add quality to your image and will usually result in a soft or blurry print. Resampling by a small amount is generally acceptable, but if you need to increase the size more than 30 percent or so, you should look into other methods of increasing image resolution (external link).

Good luck,
Artan.

All you do is make sure that your crop has an aspect ratio of 8x10. To do this use the rectangular marquee selection tool (this is for photoshop but most programs will be similar) and set the mode to fixed aspect ratio with 8 and 10 in the width and height boxes. Now drag around the area you want to crop, hit 'crop' and print. The quality of the print will be determined by the size of the cropped area relative to the original image size i.e. if you're only cropping out a very small part of the original image the print quality will suffer. You can upsample images as suggested but you should avoid this if possible as you can't create something from nothing.
