printing high res?

[steve-fisher]

I have a D60

Could someone give me some pointers on how to get the best results for magazine quality print (300 dpi).
I have been shooting on Raw and converting to 16bit Tiff format images (36MB). They are in RGB color.

Where to from there?
How big can these images be printed?
Can I nudge the image size up at all?
I heard someone mention something about interpolationin photoshop?
I heard of someone printing a 20x 30 inch image?

thanks

I am presuming you have something like Photoshop 7.0?

I have printed D60 to 12x18 and 10D to 16x24 (at 300DPI) with no noticeable artifacts. There is no difference between D60 and 10D as far as scaling is concerned (that I have noticed yet). Both cameras are native to 8x12" at 240DPI. In photoshop I have found that you can double the size and change the DPI to 300 with no noticable artifacts. I am still trying to pick one image to try a 40x60" print at 300DPI (if it fits on a single CD-RW). I am pretty sure I can go this high with only minor noise, but everytime I have a picture I think would look good I find it was one of the ones I took in jpeg mode before I went RAW only. I discovered Jpeg doesn't scale well.

I find I can usually scale by a factor of 4 or 5X before getting significant noise (assuming TIF or RAW and ISO 100 to start with).

So 16x24 should be easy, 32x48 is likely to be good and 40x60 should still be good at 300 DPI.

Trivia: I discovered that using the cropping function in PS7 works better at scaling then using image size to do the scaling and changing of DPI. Strange, but true so far for me.

Trivia 2: The place I take my images to be printed a bigger then 13x19 paper can't handle 16bit images, so I have to cut down to 8bit for them to print. Found out this was common around my area.

Just my experience and opinions.

OK, you got me on this one. How do you scale up with the cropping tool?

Thanks alot for that input. I will try all of that and see how it goes.

I'm new on this forum and will post some shots sometime from my travels.
