Calibration questions???

[jmik26]

So reading through the forums, posting and getting some help from the members I got a Samsung 245t 24" monitor along with the Eye-One Display 2 monitor calibration device. At first I did the basic calibration where it does everything for you. Today I decided to check out the advanced calibration which is where the questions come in.

Here is what I am trying to calibrate at:
White Point: 6500K
2.2 Gamma
Luminance: 120

On the next screen it has me do a ambient light with the white thing attached to the device as it shows on the screen and it is coming up:
Color Temp 2800K
Illuminance 89 Lux
According to the side notes and the indicators this is not optimal for color correcting photos?

I tried all sorts of light bulbs (CFL, white, soft white, clear, etc..) and the Illuminance gets higher but the Color Temp never gets past 3400? Are there special light bulbs or types of light bulbs that will give me a color temp that is suitable for photo editing? Is there any harm in having ambient lighting at 2800? Any help would be greatly appreciated...Jeff

Here (http://photography-on-the.net/forum/showthread.php?t=529524) is a thread that answers most questions I think ;)

Ahhhh, thanks for your help. You should get a POTN member of the year award :lol:. I have read so many of your post to help me get this color calibration thing going... Thanks again, Jeff

Well I printed off a coupon and ran to Joann Fabrics to get a Ott-Lite so I can have better lighting. I had it in my hands for about 5 minutes and the cheapskate in me didn't buy it. I figured if its a craft light maybe other stores might have something similar. I stoped at Menards and took a look and I am glad that I did. I picked up four Sylvania Craft 5000k CFL bulbs for $14.00, took them home and remeasured, now I get:
Color Temp 4600K
Illuminance 100 Lux
One more piece of the puzzle complete. I going to edit some photos and send them off to the printer tonight...

Great result!

FWIW, don't worry about saving the date in the Profile name. There's no point to it, you'll be saving a new one next week, and your system will quickly be full of redundant profiles. I usually save like this: 6500_2.2_120.icc. And I just save over the profile each time. I can't think of a single reason to keep old profiles.

By the way - the whole lighting thing? I wouldn't worry about it from a calibration point of view - it doesn't have any effect on the calibration process. Lighting only becomes a problem when you're viewing your prints.

Ref comparing the calibrated screen image to the print in the hand under room lighting.

This is one aspect I am still getting my head round ~ calibrate the screen as needed at 6500k but view the prints under 5000k illumination. I think I recall Michael Reichmann saying he uses 5000k lamps in his gallery displays.

Also that rather than have the lamp near the screen so you are holding up the print near the screen you should have the lamp behind you so you turn away form the screen ~ I wonder is this more "in the mind" i.e. 'does the print look right under 5000k' not necessarily a direct visual match to the screen???

For the record I think I need an appropriate lamp for the viewing but should it be 5000k or 6500k (northlight?) :confused:

How will you and others be viewing your prints, after that first critical examination? Home lighting, tungsten or flourescent, gallery/museum lighting, sunlight? Whatever standard you print to will be a best scenario compromise.

Hmm! fair comment. Ultimately depending on the size e.g. 6x4 in an album = light variations, could be anything from daylight to, tungsten, fluorescent to mixed. If bigger and framed for the wall there could be more control but not all such framed prints get viewed with optimal lighting......!!!!

Perhaps that is why MR went for (if I am recalling correctly) 5000k lamps in the gallery situation i.e. if/when folk buy his prints they will as good in a typical home environment....or have just confused myself even more (not for the first time ;) ) So with such mixed potential viewing conditions is 5000k or 6500k best for that inital critical appraisal?

Edit:- these guys http://shop.colourconfidence.com/product.php?xProd=1955&xSec=1&jssCart=ad649626776baaa62298cff90f772f2f offer their Daylight viewing lamp but cannot see what "colour temp" it runs at?
