I am Always happy to see that an XE, is still cranking out great memories.
I've had mine for 32 years, I bought it used for $250.00 in 1978.
It makes me sad to know that I'll be running my final roll of Kodachrome through it next week.
Nice shot of the kids, and with a cool camera. NPH doesn't like to be underexposed, better to go slightly over if anything, I used to rate this film at 320 in my wedding days. On my monitor there is a very slight cyan cast, but that could be down to the processing rather than exposure error. NPH usually has great skin tones, but I have found that the new Kodak Portra films are even better.
Nice picture of the girls. It looks slightly yellow and cold to me, which suggests that you need to take out some Yellow and Cyan, which will add blue and red to the picture. This what I would do in the darkroom.
If you do a have a colour cast of people, then a warm colour cast is preferable to a cold one, usually.
My monitor by the way, is not calibrated.
As for colour casts on prints being eliminated, well that really depends on the operator to a fair extent.
Exposure looks fine, maybe the print is a little light. It's a bit yellow and yes, as Mick said above, cold or cyan. Need to put some pink in their cheeks.
Here's a good example of colour being in the eye of the beholder. This is primarily a picture of two kids so skin tone has to be right and in my opinion the skin tone is spot on. There is a slight pinkish tinge on both girls faces. I suspect that the lower girl tends to be slightly more ruddy in complexion in real life. If she is then the skin tones are spot-on as this is reflected in the picture. Skin tones are muted but everything here says that this isn't high summer so too much warmth would look unnatural.
All the colours on my monitor look to be right. If you get a print from this neg that matches the neg scan I think you can be very satisfied.
Colour balance can be a very tricky thing. If I was printing this again I would use a little red, looking at their hair colour I can see a little cyan cast. I'm suspecting that the original light was a bit yellow, late or early in the day? Best to leave this slight yellow cast otherwise your shadows etc will go cold.
I agree with pentaxuser in the eye of the beholder, but I have found that most people prefer a warm bias to the colour of skin....probably why I now mostly shoot B&W!
