That's going to be a big help, Ed.

I typically take up to 15 batches of up to 20 shots per day. The batches are run through Helicon focus and then resized for my forum gallery.

Faststone allows me to resize with a few clicks, so if I don't have to save the image between steps, it shouldn't be too onerous.

Thanks again.

Well, I and a couple of others have run some tests with my original shot.

Starting at 4928 x 3264, we started down sizing to 3000 2000 1000 and 800 long side measurements. We could see no improvement between stepping it down and going straight to 1000 or 800.

I then tried sharpening the image by the tiniest amount which would show a change and it looks 'orrible - very grainy.

I'm beginning to think that the D 7000 won't produce an image good enough to cope with any downsizing. My wife has a D 90. I might give that a go and see if it's any better.

The problem isn't your D7100, but the software.

Different programs use different algorithms to reduce the image.

Taking a D600 native 6016x4016 @ 300DPI, 20.05x13.39 inches, 24.16 MP, and reducing it to 6x4 1800x1202 2.1MP @300DPI louses over 90% of the pixels.

If this 6x4 is printed at 6x4 it will look as good as the original printed at 20x 13.39 on the same printer with the same settings.

If the reduced 6x4 pic is printed or displayed on screen, at a larger size it will show loses.

Here is an image from my Fuji XE1 16MP and the orginal jpg is 13.2Mb so the resulting resized image is 227kb which is 1/60

Amazing how much detail is still visible with only 1/60 of the pixels.
