Image resolution?

Is there a way to change the image resolution and maintain the same image size?
I have a 320x240 image @ 96ppi
I'd like to maitain the size but increase the ppi to 300.

Image>Image Size>Select Resample and Bicubic Smoother and set the Resolution to 300>Enter

But F1 would also be a good place to start.

Yes that will resample the image, but to jump from 96 to 300... that would damage the image, no?

If you scale up the resolution in Photoshop you will probably damage the image. I don't think the Photoshop interpolation routine is too good about a 30% increase in dpi.

Try Genuine Fractals Pro from LizardTech. The Photo Library I submit to recommends it and I have been pleased with my results.

Well, not if you're on PS CS. Resampling with Bicubic Smoother does the step by step process in one step. (Bicubic Sharper for downsampling) You may want to do some sharpening before and/or after.
(here's some info:http://www.outbackphoto.com/workflow/wf_60/essay.html)

If you're working with PS 7 or less, you're stuck with steps. :( There's a nice action on Adobe Exchange by Francesco Franceschi called 'FFrank's Less Loss Resize' It will do the step and scharpen in between process for you. Works quite well.

It's a small step for PS CS, but it's one giant leap for mankind

I just saw there's a step upsizer too on the link a gave before.

you can download it here:

Thanks for the help and that link.

V1nc3nt,

Thanks for the tip. I wasn,t aware of this.
I have Photoshop CS and tried just that (Bicubic smoother). I started with a photo at 72 pixels, 7x5 inches and took it up to 300 pixels per inch.
It became very fuzzy and no matter how much unsharp mask, it remained a bit fuzzy.
I suppose there must be a certain tolerance to what "bicubic smoother" can do.

Cameraman,

I went to their site. It's expensive!
I recall a procedure Scott Kelby showed (to make posters out of phtographs without appreciably changing quality).
The whole idea is to go to "image size", checking "resample image" and changing "inches" (cm) to "percent". Then, changing 100% to 110%, clicking OK. Again, you open the "image size" and repeat the process. You can do this by 10% increment without seemingly damaging the photo. I created "actions" to do just that.
If the photo is good to start with, you can blow it up somewhat. Cheers,
Marcel

There is an ever lasting discussion about resampling. I think in the end it's not about what method is best, but what result your satisfied with. As always speed against quality.

Well, if you want to spend that kind of money you can also look at SizeFixer by FixerLabs.
