Can anyone help me !!!!
When i print snow photos they seem well they do come out blue .
On preview they seem fine but when i send to print the problem then starts.

You could sample the colours to see what values the offending areas have. The RGB values for pure white are 255, 255, 255. Where the snow is very pale but not completely white the RGB values will be slightly lower but, if perfectly neutral, the values will in theory be equal. If the values are out of step with each other then the snow is off-white because there is an issue with the image. If the values are pretty much in step then it is an issue with the printer.

You could post the offending image for us to see and comment.

Could be that your monitor needs calibrating or your printer settings require a tweek

without the proper filters for snow you do get a blue tint, only way around it now is to desaturate on the blue channel

Not sure what Paul's refering to with 'filters for snow'??,but if the problem is prints not matching your screen as you say,the most likely cause is an uncalibrated monitor,inadequate printer/paper icc profiles,incorrect print settings.

When using film you often get a blue cast if you don't use a warm-up filter. I think you can control this in processing if you use digital (colour temperature)

The problem according to the OP wasn't at the taking or processing stage but at the printing stage when the image didn't match the screen.

as I said use desaturate in photoshop or other, then do a series of test strip prints till you get the required white snow etc

A more reliable and consistent method is to use a calibrated monitor and correct icc printer/paper profiles,printing test strips every time will result in un-necessary expense,wasted time and lots of frustration.
Desaturating the blue channel slightly, sounds like a good sugestion though.

Don't worry about blue snow, its yellow snow you have to worry about.

Or no snow at all - that's even worse...

Second guessing:-

Unless you compensate via exposure or filter White Snon will look slighty Blue. It is possible that in preview there is actually a slight blue cast, that you didn't notice. When printing this blue can be acentued by the printer thus appearring bluer than the preview. Mike

It's extremely tricky stuff, snon.

The white balance is the least of your problems... wait until you realise it doesn't even exist


muhahahahahaaaaaa


Stick to snow. It's a lot more predictable in its response to light.
