lack of contrast and brightness in rendering

[max.m]

hi there,

this is my last project. first image is the rendering, second one after editing in photoshop.

especially in this interior i realsided that a lot of my interiors look very flat and dark, i only get satisfying results with a lot of post work in ps.

can someone tell me how i can rise the brightness and contrast in this rendering?

vraysun intensity mult:1,5

vray sky intensity mult: 3,0

cm: reinhard mult: 1,0, burn: 0,3, gamm:1,0

all objects with glasmaterial on`t cast or recive shadows, and are excluded from gi

 

very thankfull for suggestions,thx

Try setting your gamma to 2.2.

the reason why you have no contrast is due to your values of sun and sky ... bring them both down to 1 and then change your camera settings to an acceptable level

thanks for your replies,

 

i followed your suggestion and set vraysun+sky to 1,0. now the rendering has more contrast, but is also much darker than before.

my vraycam settings are:

f-number: 5,0

shutter speed: 300

iso: 100

which setting would make sense to you to tweak to get more brigtness into the image without loosing contrast?

for that you will have to study on real life camera situations and see what they do

As mentioned set sun to 1 multiplier and if you want to push more "skylight" into the space use a vray sky and tick manual and change the multiplier to about 2. 3 is pretty high, and will wash out the effect of the sunlight.

 

The Rienhard will also affect it seriously. A burn value of 1 will give you contrast, less than this will bring up your midtones and sometimes flatten the image, as it moves from a linear to exponential curve from blacks to whites. Change yours to 1 and you'll find you get more contrast.

 

If you aren't using motion blur, you can just keep ISO and shutter speed as 1 or 100, same effect in essence as long as they are the same value; and change your F stop to adjust the exposure. Just up or down until you have the right exposure, just like a real camera!

 

Hope that helps.

dont do this unless you know wot your doing - it will make your image more washed out

 

just use the phys cam properly and add a few fill lights if you arent getting enough light.

personally i really like the second image, i think it only needs a bit of photoshop

[Dave Buckley]

i've gone a little overboard with the photoshop but i hope you don't mind, i made some minor adjustments, curves, levels, colour adjustments, brightness and contrast. took about 5 secs but instantly more contrast

agreed. just upping the gamma a whack isn't the answer
