Please help as I am totally confused. I use a Canon 10D and take most of my photographs in RAW format. I then use Canon Digital Photo Professional to view the photographs and make any changes necessary. Now I want to convert and save to TIFF. My RAW file is 3072 x 2048. If I want to get a print larger than A3, should I resize now in Canon Digital Photo or resize in Photoshop. I wanted to be able to get a print around 24" x 16" if that is possible, and at what resolution. Thank you.

I'd say do it in photoshop.
Set your image dpi to either 240 (usually more that enough) or 300.

Then use the 105% method of doing repeat 5% increases until you reach your final size.

This will yeald a huge file, that I have discovered places like CostCo kosiks can't read.

Or get the trial version of Genuine Fractals and give it a go, I think the trial will allow you to do 10 images before it quits.

It has been sold to ononesoftware so I don't know what they have done with it. http://www.ononesoftware.com/detail.php?prodLine_id=2
They also sell pxl smartscale.

In the latest releases of PhotoShop they have introduced the bicubic smoother resampling mode. This pretty much makes the 105% method and genuine fractals unecessary.

Another new thing to try :-)
The new PS CS2 has a lot of new features to find.

Bicubic smoother was added in PhotoShop CS. Not CS2.
I have CS I just checked... and it's there.

But the 04-cent question is ...
... is it better than the good old 105% upsize.

Not necessarily better but as good and a lot quicker and easier.

I've heard varying opinions about using bicubic smoother all the way vs. %105 enlargements. I just made a keyboard macro that does it (so its easy) and then completely the enlargement when I need less than %105.

I've read the same thing about genuine fractials. That you don't need it, or it still does a better job. Don't know myself, I don't own GF.
