problems with displaying my renders

[fadi3d]

LWF This subject is driving me crazy and the more I readabout it the more I get confused.

I mean I’ve read about it extensively in the 3Dats book andmany tutorials on the net my settings are:

In 3d max Gamma and LUT: Enable gamma /LUT is checked,Affect color and affect material checked,

Input gamma 2.2 and Output gamma 1.0

As for Vray Color mapping: Linear multiply , Gamma 2.2(Although here some say it should be kept 1.0)

Affect background and don’t affect colors checked.

In Photoshop the color space is sRGB

My screen is calibrated using X-Rite i1Display 2

I save myrenders as Open EXR 1.0 open them in Ps ceonvert to jpg with minimal coloradjustment and the occasional Dof using the vray Z depth

The result myrenders look fine on my PC and on my Samsung mobile Galaxy s2 but at the officethe look dark and when posted to the net people tell me they look dark.

Am I doingsomething wrong??? and if other people should calibrate their screens then what’sthe use of me calibrating mine???

I’ve attachedan example

I hopesomeone will be able to clarify this issue once and for all.

Thank youall.

Regards.

This is a common problem with no solution, the issue is that most people are using un-calibrated monitors and they aren't even aware of it. Monitors come un-calibrated from the factory, it takes special software and hardware to calibrate them as you know. Unless the person viewing your images calibrates to the same settings your using the image will look different. For color critical work the only option you have is to print out your work on a printer who's output you trust, then have the client judge it. It's a serious problem for people doing work that depends on color accuracy, I've been fighting this problem for 12 years and there's no good solution.

Hi, This view seems normal for a raw render with such a small indirect light source. You can alleviate the darkness in a couple of ways. You can place a vertical vray plane light the size of the room that is right behind the camera frame shining into the room and adjust the brightness to your liking. You can also use the Environment G.I override to increase the ambient light which will make the interior lighter. I've been using a value of 1.0 with Exponential color mapping and I'm very please with the results.

 

Also in a space like that you would most probably have a ceiling light of some sort.

The image looks fine to me in Firefox and I Explorer. It actually looks a bit brighter and colors more saturated in I Explorer. Firefox is color managed.

My display is profiled with a ColorMunki Photo.

I adjusted the luminance for 100 also as stated. I say again that your image looks fine at this end and the lighting is well represented.

looks fine to me

Guys than you all for your valuable input

 

@ Devin. That is exactly my reasoning I mean I bought thee quipment for calibration and went through the trouble for what ? especially that nobody here, wants to see the print (with all the I Pads and Galaxy tabs etc…)

 

@ George. This render is a match for a real (some Italian brand furniture for kids and teens) photo hence the absence of ceiling lights and actually I came real close to the real one (pls see new attached render) in reality there are two more lights behind the camera or else it would’ve been much darker.

 

@ Ismael. I will check the link and if it looks good infirefox that is fine (but do we have then to render for specific internet browsers now ??) and pls can you confirm if it looks close to the new attached render ??

 

Please guys do check the new attached render that is almost what the old one looks on my pc at home.

 

note the less saturated colors especially where the sun beam hits the ground.

 

 

It is the same render duplicated in ps and screened (50 %)

 

Thank you all.

Last one is more brightness and more realistic the first one. good job..

Always have this problem! My screens display images differently to others in my office and we all do vis. If my images are opened on anothers computer the first thing they say is it needs brightness/contrast but my monitor has brighter and more contrasting colours so it looks great on mine!

 

It's one of those things we live with because even if you calibrate, three months later the chances are your monitor needs re calibrating to be correct again. We have a good printer that we print our images on to get the colour accuracy.

 

I totally agree with Devin! It's something we just have to live with!

 

PS. The image looks great to me!

I used to use the I-one match color calibration package, it cost us about $1000 and I used it for years. It was good at calibrating screens and printers and I calibrated anyone's screen that wanted it since we all worked on the same projects it makes since we all should be seeing the same output. Calibration isn't a one time and done thing, you have to do it regularly because your monitor drifts out of calibration. This is just something you have to maintain like changing the oil in your car, the monitor is the only thing we have to judge if an image looks good so take care of it. If you don't want the hassle of calibration then purchase a monitor that comes pre calibrated with Adobe RGB preset modes.

 

You have to make color calibration on monitors, screens, and printers a way of life within your office because once an image leaves you have no control over it. Clients do not understand this and you have to teach them that when it comes to judging color your monitors or printers are the only acceptable way to do it. You should also find a printer in your area that has a good high end printer and can reliably reproduce your work. The best type of printer you can use is a Light Jet, it takes digital files and prints them using a chemical process much like how pictures are printed. There's a company near me who has one and every image we print looks exactly like what's on my screens, unfortunately they don't make this machine any longer but if you can find one it will make your life much easier.

If I could marry a lightjet, I would. I started using one in 2000 and the prints were always fantastic.

Oh oh................. What about Dalice? We now know what those jealous women can do!

[fadi3d]

with all respect guys i don't think the problem is in printing (at least for me) as i don't even print or rarely do.the problem is why the render is displaying on other screens as if it is not gamma corrected and on my mobile (which i don't know if it can be calibrated ) it looks right.

Fadi,

 

Please see this section of this site where a lot of your questions will be answered, http://forums.cgarchitect.com/204-color-management/

Read through it and compare the experience of others to yours. Also look for these in a search engine, "color management", "monitor calibration and profiling",etc.
