Photoshop Question

Hi Guys,

I want to get an 8 x 10 print of one of my images but the problem is I had to crop it pretty heavy to get the composition I wanted.

Now when I go to upload the image to Ted's Printing Service it says that it is only average size file and not recommended, so I need to upsize the image.

How is the best way to do this without losing to much detail? I don't need to upsize much as the image is currently at 1120 x 838.

Thanks for any info you can share.

Woody, unless you utilise some sophisticated interpolation software, one way or the other, you are making a bigger picture out of the source that you have.

You can make the file bigger, or you can ignore the recommendation at Ted's (which is probably there so you can't complain if the print comes out all "blocky" or otherwise crapolla.)

A friend of mine got some 2 megapixel images printed at ted's at 10x8 and the results were surprisingly OK.

You, however, have less than one megapixel, and there may be trouble ahead.

But whether you increase the image and file sizes in the computer, or they do it at ted's, there are going to be compromises.

This is my view, see what others have to say

Edit - In view of subsequent posts, I would like to
a. disagree with myself, and
b. stand corrected

Doh!

G'day,
Don't know if it would help or not, but you could try up-sizing the original and then cropping again...

Dunno if it would help or not, more knowledgeable PhotoShop people will probably come along later and offer some better advice...

Cheers,
Mudder

Amongst one of my fellow students who were doing a digital photography course was a guy who wanted to print 1m x 2m (well allmost).
He applied a procedure where you increase the size of the photo (in your case crop) 10% at a time. He ended up with a gigantic filesize and the print was superb.
I guess that you perhaps could apply the same technique to achieve the size you need.

there's a photoshop action that i've got lying around here with increases the size by 10% as previously mentioned... i'll find it and put it on my webserver for you... i've used it and the quality is wonderful.

If you have a spare few quid invest in the program that nnnnsic uses.. can't quite remember the name...

If you can afford it, Extensis pxl SmartScale.

The 10% increase per action in PS works basically in the LAB mode on the lightness channel and is a wee bit tedious. Also not recommended if there are lots of straight lines.

There are 2 programs available that are very good one is PixelScale and the other is Genuine Fractals.

10%

The 10% method is called something like "step" scaling but I can't remember the exact phrase. There are programs around that can do much better scaling than the step method, two have been mentioned already but the one I use is called "Photozoom Pro" and uses a funky "S-Spline" method that can even anti-alias straight edges and text to clean up the blockiness of enlarged images.

If you google "Photozoom" you may find a shareware version but if you struggle too much, email/PM me and I could do it for ya!

One thing you can try I have done it before & it turned out OK.
Have a look at the image/ image size & what DPI it is.
Try changing it to 300 DPI, then have a look at the file size I think you will find the size will grow some what.
At the bottom of the box there is a check box saying resample image, make shore this is ticked & “Bicubic Smoother” is checked in the dropdown list.

Hope this helps.. :wink:

Cheers
Ray :P

I second the recommendation for Extensis Pxl SmartScale. You should be able to download a 14-day demo from http://www.extensis.com/en/downloads/

To the best of my recollection it works fully in demo mode and is a great program.

Regards, Tim

Hi Ray, howzit going?

I checked out the Luminous Landscape review: not too complimentary, is it? However I found it worked beautifully when I had to scale up a JPEG-compressed 3000 x 2000 pixel file (originally shot for a catalogue image) to A1 poster size for offset printing @ 260dpi. SmartScale did a much better job than PS7's bicubic interpolation for such a grunty process, but I have to agree with you that PS CS's 'bicubic smoother' option is great as well.

Regards, Tim
