The best method for downsizing for the web would be:
1 - do all image manipulation at full resolution
2 - Using - Image / Image Size - to resize ppi and long dimension pixels AT
THE SAME TIME, ENTERING THE PPI FIRST.
3 - Run unsharp mask to recover the sharpness loss from resizing.
4 - Use Photos

Best downsampling is exactly half length ;for example 1800pixel wide down to
900pixels wide. Some scannerprograms, such as Agfa Color exact2.1, are far more
sophisticated then photoshop in unsharpmask and a correct sized correct
sharpened scan is best,you will then avoid additional use of unsharp

Hi Laurie,
With mutual respect to your response.
Genuine Fractals has no current place in web image preparation. It's only
use is for upscaling data to print large images. We went through this same
discussion on another forum (Nikon CoolPix 990) about three weeks ago and

I didn't say it was, but it does do 'interpolation' in the 'dictionary'
definition of interpolation in the process. I agree it does more than
'standard' interpolation My understanding is it converts to vectors in

Just a question:
Is it better to first downsize an image before doing a high-bit->low bit (I
mean 16 to 8 bit as Photoshop calls it) conversion or does it not matter?
I initially assumed that a bicubic resampling on high bit data would give
better samples, but it takes more time too and I just w

People of the list,
Thank you for your on-list and off-list replies. You know, it's not that my
images are really worth the fuss, but it is the feeling that counts for me
that I retain most of the original info and hopefully quality in my image
edits.
Thank you,
Jerry.
