High resolution??

[Lance]

Hello all...
This might sound like a silly question, but I went to order a print off flickr and they kept telling me that my Photograph was of low resolution. So I took it back in P/s and went to Image size and bumped it up to 250 res which appeared to work and the order went through.
My question is;
They recomend a resolution of 1152x 1728, I don't understand how there is two numbers?? Where do I save this??
Many thanks Lance..

resolution and pixel dimensions are often interchanged, what flickr mean is 1152 pixels wide by 1728 pixels hgih, and I think you may be talking about 250 dpi ?

 

[Lance]

Every time I am putting 1152 as wide, the height will automatically change to 767 ???
1152x1728 are still not achieved???

Stick 1728 as wide and the height will be 1152

Great that worked...
So what is the resolution for at the bottom of document size in P/S for? As I up this to 250??

You can't up it, changing the resolution will only change the image size, thus a 1728 x 1152 pixwl image at 100dpi will give you a print size of 17.28" x 11.51" whereas a 1728 x 1152 pixel image @ 250dpi will give you an image size of 6.9" x 4.6". The number of pixels won't change, just their density!

Thanks Andy for the link...
I went to order another print today and put in the deminsions 1728 widthx1152 height and saved the image. But!! On ordering the print, they still came up with a warning, saying the image is of low resolution???? The print was for a poster print, but these are the demensions they said to save it as??

What size are your images straight out of camera?
