Scanning Picture Process

[Ross Lowry]

I am wondering how you guys and gals scan in pictures that you going to resize larger?
I usually scan them in at the original size and the dpi I am planning on engraving it at.
Then use geniune fractules in photoshop to resize it.
After that I run it through photograv.
Usaully this produces good results, but sometimes not.
I have read about people scanning in at a high dpi, but I have not tried this.
Thanks.

I usually will use the "acquire image" function in Corel to scan it in at the
resolution I want, then resize to fit the template for the substrate.

Thanks Joe.
Why do you think people would scan in a picture at a very high dpi then resize it and drop the dpi?

I used Genuine Fractals years ago, It seemed though I had to print out of that program, is it a standard plug-in now for photoshop. For what it was it did some amazing things!

I scan at maximum resolution. If you resize the image 3x size you are reducing the print out by that multiplier. IE scan at 300dpi scale 3x you are now only 100dpi. This why I also shoot film at max. you can always take away but it is dificult to add back in.

If you do a little math you can scan at a high DPI and then scale to the output size without resampling. ie...

original image: 5" x 5"
output size: 20" x 20"
desired output resolution: 300DPI

The final size is 4 times the original so:

Scan setting: 400% at 300DPI
or
Scan setting: 100% at 1200DPI
then resize to 20" x 20" with resampling disabled

Resampling is not a good thing to do. Especially upscaling. The pixels are interpolated to fill in the missing information.
