Hello all,

I have a Kodak Z7590. This is a 5.0 mp camera. Whenever I bring the pictures into a photo editing program after taking a photo at the 5.0mp setting they are always 8in x 10in. Is there anyway to increase the size of the photos the camera takes?

Thanks Alot.

I am lost, LOL. Do you mean in the editing program? Or within the camera? What file type are you taking the pitures in?

Sorry for the confusion. When I open the picture up to print it or edit it in photoshop the photo shows as 8in x 10in. The pictures are taken as a JPG by the camera. I have the camera set to 5.0 mp. According to Kodak when taking pictures in 5.0mp mode you are supposed to be able to take pictures up to 20 x 16. I am wondering how to make the pictures that size.

Thanks again.

O.K.- I believe that what they mean is that you can take a pic toprint that large? Maybe I am wrong, but which camera are you using?

Have you tried taking the pic in TIFF? Or RAW? That is a larger size file and may affect the size you see in your photoshop editor.

Where the heck is MT when you need her?????

There doesn't seem to be any options to change the file format. I don't really understand why it is only taking up to 8x10.

Maybe because it is the size that your printer is capable of printing? My photos can also be enlarged to the size you want but only by an outside source.

The print size depends on the¬* print quality you need, normally represented by dpi (dots per inch. A 5 mp camera in 4:3 format takes a picture in a 2576x1932 (more or less) pixels resolution ( multiply and you'll have more or less 5,000,000 pixels... that's 5 mega (millions in this case) pixels in the photo. That means, horizontally you have 2576 dots and vertically you have 1932.¬* If you want to print in 300 dpi (the normal "foto quality"), using math, you'll find that the max print size will be 8.58x6.44 inches (2576/300 and 1932/300). So, if you want a larger size, use less dpi. You'll eventually notice the quality loss when increasing more and more the print size. So, to print 20x16 inches, you'll have to reduce the dpi's to aprox 128.

Could you take a screenshot of what you are talking about that is showing 8 X 10? It isn't possible for a camera with a 4:3 format to display a 5:4 format like an 8 X 10 without some cropping.

Most 5Mp cameras come up originally looking like this:



If you change the height to 8 inches without a resample (without changing the actual pixels) you get this:



It can't give you 8 X 10 with the original ratio of width to height. You would have to trim the image by cropping the edges a little to have it display 10 inches in width rather than 10.667 when you have 8 inches in the height.

Notice that if you don't change the pixels with a resample the PPI changes as you change print size. I can't see any difference over 240 PPI.
