Kung kayo po ay gumagamit ng ibang calibrator - yaang adobe gamma should be put off.

And Adobe gamma ay isang software application to check the same thing minues the equiptment. I haven't used adobe gamma but my calibrator comes with its own software controls.

I am sure meron din mga free application to somehow help with gamma settings. Post ko dito pag nakita ko ang link.

ah iba pa pala yung calibrator sa adobe gamma, ang akala ko yun na yung calibrator mali yung pagkakaintindi ko sa nabasa ko sabi kasi, "When calibrating your monitor, set your whitepoint to 6500K", salamat sir medyo maliwanag na kaunti magegets ko rin ito,

ryancoy wrote:some tips when using LWF

*if you decide to put 2.2 bitmap output sa preference make sure you are using a non hdri to lit your scene.It has something to do with the hdr itslef. If you are, you can switch to 1.0 bitmap output and manually configure hdri as gamma 1 when using it as a map which in my own opinion seems like mental ray is easier to setup in terms of linear 2.2 in max kaseh naka embed na cya sa exposure tab nya eh. Vray is not that straightforward imho.

*always use Vfb
*never use mfb as it will double gamma your scene(making your scene super washed out).
*if you want to bake the gamma into your renders make sure color mapping is set to 2.2 or if not @ vfb srgb is turned on.
*others prefer to use color correct plugin rather than bitmap output 2.2 in max preference because they deal with different file for bitmaps and each one has different input for gamma (jpg,png,HDR)
*when saving your images in lwf i would recommend exr, hdr or half floating point 16bit tiff. The explanation for this is it stores more data whenever you want to tweak ur gamma or exposure settings in photoshop, you wont get as much noise as you would normally have on an 8 bit jpeg image. Thus the reason for very huge file sizes.

*the thing i find irritating when using from linear 1.0 to gamma 2.2 are actually the reflections/glossiness or refraction levels. when you switch a 1.0 scene to 2.2 turns out to be more reflective because its making the values of your reflections more higher in gamma 2.2

I dont have any intention to confuse anyone. The tip is actually to those who are using it already and to those who wants it.
Actually any workflow that best suits you, then go for it. No need to switch just for the sake. As long as you can interpret your art the way you should then i guess thats fine.

Ill post a sample lwf scene tomorrow vs a 1.0 just for a comparison.

Peace

glad to see you are now a believer

anyway i found the link in which alex roman says he uses LWF

read post #44 and #49

as for your renders in LWF looking flat, try a 0.5 secondary bounce multiplier in your vray indirect illumination dialog box. or just sparingly use filler area lights as you do not need as much filler lights anymore when using LWF, this also goes for vray skylight, a little goes a long way.

When loading bitmaps make sure that the gamma is set to use " USe system gamma" or even you even want to make sure, "Override gamma" and set to 2.2.

opo i have followed these steps - my old bitmap settings have output overrides - i adjust the curves to be darker than usual to avoid blownout highlights. ( i always render with exponential settings BTW ) with LWF i used input gamma and all textures are set to use system gamma (2.2).

the washed out look occurs because majority of my "greys" have become lighter than previous, and the reflection values as ryancoy pointed out have become too high for LWF. arigato gozaimasu
