what is the difference among exponential HSV and linear
hsv keeps your colors when increasing your dark multiplier vs just normal exponential, and exponential is better at brightening areas without bleaching them out then linear.
that answer your question? 
thx alot man… 
i just want to mention that not many ppl in this forum replys…there r only like about 6 guys in total answer questions…i am not gonna say their names here…so i am so thankful that psy u replied… 8)
wish u a merry christmas and a happy new year..
best regards…
np, merry xmas to you too! 
the reason we reply is we have no life man. hehehe. kidding
life
life whats that…
but what do you guys generally use and in which situations
i seriously dont no…and i want to no…
hsv exp and exp are really useful for interiors (especially hsv) where you have sunlight coming in through a window and you need the room to be bright, but not have the light shining on the floor be just a white blob.
linear is good for something i’m sure, but i don’t personally use it anymore unless I just need some simple tweaks and I’m too lazy to do it in photoshop
well…what do u use usually?..hsv / exp???
hsv for interiors mainly, and exp for anything else basically.
sometimes tho, hsv doesnt work perfectly and you need to use vrmap desat to fix severe color bleeding probs.
no method is perfect however, its all about learning what works best for your situation and going with that, be it hsv, exp, linear, vrmap desat, or photoshop.
I didn’t reply because i didn’t know :)))))))))))
didnt even know there was an HSV exponential type :lol: :lol: :lol: :lol: :lol:
(kidding, but its very new right?)
sorta, prolly been there for like the past couple months i think.
thx psy
i use linear on exteriors,
any specific reason why?
on interiror things tend to get darker very quickly, exponetial exposures is like a big boost in your gamma. In exteriors, things tend to stay pretty bright as you don’t care so much about how much light bounces around and decays as it does in interirors. This is also true with real photography: ever take a picture of a room with a bright window in the frame? It tends to be very dark except for the window. Color treatment and exposure control of the film process can help control that effect and make the room look brighter while keeping the window at the same exposure. Using an exponential exposure in Vray is similar to that.
