Reading through this I see a lot of wasted type. The bottom line should be - you process for web viewing one way and you process for print another way. Monitor calibration is independent of those processes. If the calibration is right, the processing should be as well regardless if all other settings are correct. Does this make sense? Or am I over-processed?

Who made that assumption? Haven't seen it in this thread.

Calibrating your monitor is a simple process. But you must invest in a hardware calibration device. There is really no substitute for that and it is an investment that will pay for itself over and over - if for no other reason than the peace of mind that comes from the knowledge that you are seeing things the way they ARE.

A calibrated workflow starts with a calibrated monitor. That is the whole foundation for everything that follows. What is the point of having a calibrated printer if you are sending it uncalibrated info?

I have used a Gretag Macbeth eye-one display2 for many years with my EIZO ColorEdge CG223W monitors. The monitors have their own calibration routine in their EIZO software, but the Gretag software should yield similar results. There's one on ebay right now for $40.

Are you certain about this Richard? On my iMac 21.5" adjusted to full brightness I see every segment. Then if I progressively turn down the brightness I still see every segment, almost until the screen becomes so dark that I can't see anything at all. The only segment I lose even then is the last black step. There seems for me to be no practical correlation between screen brightness setting and tonal discrimination.

The effect of setting brightness and/or contrast to 100% is going to vary by image viewed. For example, if an image is properly exposed to have a histogram with no blown highlights, but plenty of bright whites, those whites are going to be blown out highlights on a monitor set to an extreme level. It follows that a monitor set to maximum brightness is sometimes essential in bright daylight use. But, if same monitor setting is used to adjust images in preparation for printing, the printer is going to generate a darker than normal image. And, the user will be confounded by the process.

This thread is a discussion about the merits of calibrating your screen. Or not. Stick to that.

ok, so how do I calibrate my laptop and desktop? I've never done it so I'm totally clueless. So if you could please tell me how I'd be happy to do it. But keep it in simple language...lol Assume that I know NOTHING about this at all. That way the masses here can actually DO something about this...(I'm willing to...and I'm sure others are as well but we're to afraid to ask "how").

Possibly a step by step tutorial????

Fast and dirty method: Just adjust contrast and brightness until the bar at the bottom of the voting screen has pure white and pure black at each end, and you can distinctly see the steps between.

both of mine have the distinct steps...so doing "nothing" could be best? Or should I take it further?

I do my own printing. Wedding and commercial work usually involving extensive photoshopping. If I don’t calibrate my monitor on a regular basis, I get a shift in colours which means I need to re-edit, (wasting time), and it makes my print costs higher. When possible, I will actually print the proofing images for their review. This eliminates the “unknown calibration status” of my clients monitor.

So is there are better way for me to check my calibration? Again....I'm clueless

If both have distinct steps, and both start at pure black and go to pure white, then you're good. (*color calibration is a whole other beast, my advice is to either buy a calibration device, or forget about it)

as long as you dont vote less than average on someones image, you should be fine.

hmmmmmmmm I have a tendency to vote higher...is that a problem?

I'm genuinely confused; how will calibrating my monitor make my judging of photos 'fair and objective'?

Unless I change the calibration between viewing one photo and the next, or my monitor is so ropey that it changes brightness/contrast between viewing one picture and the next, then surely it's a level playing field for all the pictures I view?

Maybe the OP's pictures are brighter or darker or have a wider range than everybody elses? But that doesn't seem likely. What am I missing?
 02/05/2015 01:15:07 PM · #43
I'm confused, too. Do monitors need calibration so often?

And I'm curious, when editing, are people adjusting color & contrast by eye, looking at the screen?
 02/05/2015 01:21:50 PM · #44
as a courtesy to each other Richard is recommending we all to create, edit, view and vote on images on a display that is as close as possible to each other.

its a fair request, but courtesy has nothing to do with it. when you display your images on the net, the display quality at the mercy of the viewers hardware, the creator has no control, nor should they really expect any.

Printing? I thought you were referring to courtesy in voting. I misunderstood.

Calibration threads come up from time to time. I can remember one quite a few years back that someone said that voting from laptops was a bad idea because they weren't calibrated the same as desktops. I was shocked by that because up until then I thought it was an even playing field. I was doing all my voting from a laptop at the time. When that laptop died I replaced it with a desktop. It has a darker resolution & so I adjusted my photographs to suit my viewing taste without calibration. I know of a couple of challenge entries that I did that were effected by bad (non)calibration. They looked great on my screen at home but bad on my screen at work. The comments I received during voting reflected what was going on at the time so I know that having a poorly calibrated screen will effect how people view your photograph. I agree that a good photograph will stand up for itself but for the rest of them you need every advantage you can no matter how trivial you may think it is.

This brings me to another question..

When I edit in lightroom, I have started and am learning to rely heavily on the histogram..

So, with that being said and the calibur calibration of the monitor, how does that make a difference with things, if everything is great on the histogram in lightroom, pushed out in the Srgb things should show up just fine no matter what screen PC or desktop you use correct?

the histogram is great to see if you have detail in the bright or dark areas, the monitor and thus your eyes will determine how the intermediate tones look.

Why is everyone jumping on Richard?

If you're doing photography, does it makes sense to make sure you monitor is showing you the best range possible and not losing the darks or the lights?

Yes!

All he said was to check to make sure that the scale at the bottom of the page shows you what you should be seeing.

Could it have been phrased better: yes. Does that negate the information? It shouldn't.
