Over exporsure

When I render anything max 9 this the max2indigo script. I images are over exposed. How does f-stop realate to the image. must it always be set to around 22 to get a good image.
Another question is if i have a scene and i send it to indigo, must all the materials be indigo materials?
Thanks in advance,

if you are rendering an exterior scene 22 fstop is too much light you should use 5,6 or 6-8. Use a shutter speed of 125-250 and ISO 100
For interior scene use shutter speed of 30 and ISO 400 the fstop can be 6-8

There is no real ISO and shutter-speed implemented to Indigo yet.
I also have no clue why max2indigo renders everything so bright by default.
Try to set your F-stop to 8 and turn on Reinhard tone maping. Begin with pre and post both set to 2 and go on from there. pre is for mid-tones and post is for white tones.

Yes, all the models must have indigo material. Otherwize you'll get an error message while exporting.

Eh.. a thread from december last year. Damn..I feel old.
Hey Van, from where did you find it?

In my 3dmax9 panel MaxtoIndigo it says ISO, exposure, and there is a slider called Fstop, yours dont have it?

Yes i do have them, but have you ever wondered what they actually change inside xml?
They are just altering linear tone maping value.
What i meant was, that there is no REAL iso and shutter support built into indigo just yet.

F-stop affects the amount of light entering the lens in real life, and also affects the Depth of field, a f-stop of life 2.8 would have Lots of depth of field, and allow lots of light in, but an f-stop of 22 would have almost no depth of field and allow very little light in
