I have finally gotten around to picking myself up a U4R. Only had it a few days and not yet managed to get out with my scope properly. However, what I am slightly worried about is the white balance.

Every shot I have seen from the camera (not only mine but other posted by other users) has a very blue hue to it. I was very used to using the 'Auto' white balance on my trusty 4500 but having now swapped to the U4R I'm really dissapointed to find out that the 'Auto' white balance is very hit-and-miss. Then using the 'Cloudy' setting gives much warmer results but still off the mark some what.

Any suggestions anyone? I have also tried correcting the hue in Photoshop, but I can't get the perfect result - I suspect this just means a little more playing though.

Have encountered exactly the same problem as Steve. Grateful for any advice.

My U4R does not display this tendency at all, so this is puzzling. Of course, Steve has settled on the most likely solution, which is to continue using trial-and-error to correct the color bias in Photoshop.

I have a SL300RT* and rarely use the auto or cloudy settings. Instead I carry a photographer's gray card (about £10 at a photographic store) and use this to set the manual white balance at the start of each session if I remember - and if I forget it's usually no big deal - I never worried about per-session white balance when I was shooting Kodachrome 64.

I have now resorted to checking the white balance manually periodically when taking shots, just as mcdowella does. However instead of using a grey card I try and find something white to check it against, usually cloud!

I also disagree with Doug, that his U4R doesn´t show this tendency. Most of the image I have seen come out of this camera all suffer the same casts. Maybe I´m a little more finicky than most though... ;0)

I didn't realize that Steve has been viewing the photos from my U4R

What I was getting at Doug, was that the blue tones seem to be a ´feature´ of the U4R. I would be amazed if every image which comes out of your U4R are spot-on every time? It just seems that unless you are shooting under absolutely optimal conditions (nice bright sun light and clear skies, without any cloud) the U4R tends to over saturate the blues in the image if used on ´Auto White Balance´ setting.

Setting the white balance manually each time is a much better solution and tends to make the images much more neutral in colour.
