I don't understand what is happening with my uploads. I had to scan this at 72 dpi and save it at max compression so it would upload. My B&W prints I scan at 150 dpi and they work great. Every time I tried to upload this I would get "image is too wide" or "image is too tall" WTF? I'll send Sean a note to see if it's on apug's end.
You need to use the Save for Web and Devices option to get a purely image jpeg that will work for you. I've noticed my scanner give darker reds and too much blue also. I tweaked mine in PS to look more like the print to get past that.
Might be the scanner but there is a blue/cyan cast here in the green shrubbery on my monitor although it's not bad and as long as the print isn't as blue it might be spot on. It's a whole lot better than my first colour print.
Worth experimenting with different Yand M settings. The Durst Comask which gives you 4 x 4x5 pics on each 10x8 sheet is worth getting. If I am right about the blue then less Y might be worth a try. Might even benefit from less Y and M. It could be that what looks a little too blue and cold is a little too cyan which is less Y and M.
As a test print it's not ideal as two colours predominate, namely blue and green. Try a neg with a bigger range of colours, including if possible a neutral grey and flesh tone. Both of those show up colour casts best.
Might even be worth a reasonably close up shot of a person with a couple of colours of clothes on and carrying a grey card. So a couple of recognisable cololurs plus flesh tones and grey. Great for nailing colours especially if you can picture the exact colours of the clothes in your mind's eye.
Just had a look at my old settings and it seemed as if with Kodak paper I got both Y and M between 40-50. So with 4 x 4x5 prints and a change of Y and M by a couple of units at a time you'll be very close, even after 4 x 4x5s. So one sheet of 10x8 is maybe all it will take.
