Post subject:  Creating an 8 x 6 print from varying size photos

I want to send some old photos of varying sizes and shapes to be printed in 8"x 6" format but I'm struggling to make it work. I've scanned them at 600dpi, cleaned them up using Photofiltre, then pasted each one on a grey background of 8" x 6" in portrait or landscape, depending on the original photo's shape. However, to make them fit the background and thus be printable in the centre of the background without cropping, I have to reduce the size of most photos. When I send the resulting images to an online photo printer, many of them are rejected as the resolution has been reduced too much. The minimum required for an 8" x 6" print is 2400 x 1800 px. I think my mistake is something to do with the 8 x 6 background, and using Canvas Size which I'm unsure about.

I need to maximise the resolution and not crop the photos. How do I make this work?

Hi Airlane,
if your 8"x 6" background is created with 300 dpi (dot per inch) as Resolution, it will be exactly 2400 by 1800 pixels.
You can see all the values in the window : File / New
Then, any size of image you can paste on the background, so long time your background keeps his own size,
your final resolution of the background does not change.
So you can reduce the scanned images (with a little bit of sharpen edges) but never the background.

Hi, it is an other subject. :wink:
In the window : Image / Image size, If the units are defined as Pixels, you can choose any value of resolution,
the quality of the image will not be modified. But his size in cm or inch will be different.
By the way, the number of pixels is the real (physical) definition for an image, and tells exactly the number of details (informations) it can contains.
The resolution is only the (aesthetical) definition (density, size) of its view.

For your question, if you maximise the resolution of the photos, with the same number of pixels,
you increase the density of the pixels per inch or cm, but the size of the image in cm or inch is reduced.
Some software applications display the images according their pixels size (like PhotoFiltre), some other according their inch or cm size.

If you maximise the resolution when the unit size is defined as cm or inch, you increase the number of pixels,
but you don't get new information in the image, some pixels are multiplied, and the display is bigger in PhotoFiltre.
