calibration problems

Dear All,

having problems calibrating my monitor. I use a eye one device and I am having problems getting the luminence right. I would be grateful if you could check out the image below and let me know if it looks okay to you. You should be seeing a well exposed, vibrant picture, cause that's what it looks like to me.

Best regards

Josh

Re: calibration problems

Yep, it looks fine to me, Josh. Clear, crisp, bright well exposed and with good/vibrant colours.

Well exposed vibrant picture - in your face.

That's what is looks like to me.

Re: calibration problems

Pol,

I took the image to Photoshop and played with levels. When I used the registration background black for my black point and the white numbers for my white point, the picture seemed to "pop". But it was "almost" to a postcard-like oversaturation. I noticed the difference when I turned off the adjustment layer, and the image seemed to be just slightly less saturated (as it probably should with that adjustment). You may want to try that experiment yourself.

I'm using the Huey for color caliabration, and for that purpose it works well. But getting brightness and contrast set on my monitor is still a guessing game. So what I'm seeing may just be the difference in calibration of our displays.

Play some if you want, but I wouldn't be at all concerned with your image as presented. On its own, it is indeed well exposed with good, vibrant color.

Joe

Re: calibration problems

Thanks all.

Much appreciated. I have received a 22inch widescreen tft from my missus as a New year prezzie and when i ran the calibration the luminence that was detected was far lower than on my old square 19inch one and lower than the target. I can't work out why.

I have also conducted a test print on the epson r1800 and the print was darker than what was on the screen. based on the print i have lowered a menu setting on the monitor called black level. No idea what that means but it did get the monitor to be closer to the print. i.e. when I edit i should get a print close to what I see.

That all said I have allowed for the fact that thr R1800 does give dark prints. Always has and it would appear many other users get this problem.

The final thing that is bugging me a little (cause I am slightly a control freak) is that the top inch of my screen looks slightly darker than the bottom inch!.

Could be a viewing angle issue I set it up last night and wil have a further play today.

Thanks again

Josh

The whole point of calibrating the monitor is that the display will be a reference standard. The printer also needs to be profiled, or adjusted to match the screen, not the other way round.

Re: calibration problems

Thanks John,

But to be honest I i haven't got a printer calibration device. In either case when i process a picture then print. I am getting the results I want and they match.

Best Regards

Josh

Happy New Year to all!

Josh, Did you use basic or advance setting on the Match software? Use manual setting (if allowed) on your monitor, you should set the luminence level to 120, the program should give you the final adjusted reading at the end of the calibration. The best way to view your printed image (ideally with calibrated printer/paper combination) is with daylight tube with luminence to the same as the screen, I have done this via using a exposure meter first take a reading from white screen then the same with a piece of printing paper (plain), adjust the light source (distance) until both EV matches.
One common mistake most people make is to view the print in either too high or too low light level (luminence), some even adjust the brightness of the screen to match the print, while the viewing condition could fluctuate vastly, hope this helps.

Danny

Re: calibration problems

The picture is well exposed on this end, and vibrant. To a point excessively vibrant, if that was your intention.
