how to save image in LWF (gamma 2.2)
your gamma settings is correct.
you don`t need press sRGB button with this settings. only bad thing is your framebufer copy will be bright and incorrect so you cant compare actual framebufer and copy of framebufer.
if you save image in 8bit format - you have correct result.
i usualy save image in tiff 8bit. image is ok.
if you save image in 32bit like tiff32 or exr - you need correct gamma in ps because this format override gamma again )) and you have gamma 2.2 from max + gamma 2.2 from saving. correct your gamma in photoshop cs2 or cs3.
i don`t know wich of pictures is correct because i don`t know did you press sRGB for saving or what is your material. the correct render you can see with all gamma settings you did and dont push sRGB button in VFB.
for work with gamma your need fix your material!!!
you can`t use material from gamma 1 in gamma 2.2
it seams you don`t understand what gamma do with your scene.
gamma remove some of black color. check attachment.
for example you set 128 in your color for reflection in gamma 1. it`s ok
but when you swich to gamma 2.2 you gradient changes!!! and your 128 becom bright!!! this happens with all color in material!! you need to correct all colors. but your bitmap textures is ok because of your gamma settings in max!!
so i don`t know what to say about your color render. its wrong until you fix your material. how can you select colors for g2.2?? just select it in your taste by your sight. i mean there is no formula to convert old color to new but for example you want to make your wall green. just set you diffuse color to green )))) if you like your green color in material editor - you will like it on render!!! if you feel your green wall is bright or washed out - just correct your green color. make it dark and more saturated ))) you need only practice in it ) it`s realy easy.
i realy hate any discussion about gamma )))) i read alot of it in russain forum there is some thread in 100 pages and more )))) there is all shared setting people need but anyway some on newbie ask again "what is gamma" or "how it works" and all starts again )))))). i know it`s my own problem ))) just never minde it ))) your are the last man with whom i discuss gamma and LWF ))))
i think you need go step by step. it looks you don`t know exactly how to make render better and try change everything without any system and understanding what you doing. so the best way IMHO is chang something a little.
your set up day render in gray material - it looks ok. then you can add color on your scene. you can assign material only for room and tweak it until you like it. then you can add color material on other model. in final you can ajust light setting. i never change intensity on sun and sky but it`s not a rule. you can do what you want. for example if your sun light too bright and you have overbright of it you can
1 change color mapping type
2 decrease sun intensity
it`s all ok if your image become better.
your light set up looks strange. i understand what you did with portal. but there is some aditional light. i don`t know if they affect your scene. can your send me your scene? i`ll set up light and share it with you. i use max9 and your cant open my scene, but i share image and advice of it.
