Hi All,
I don’t get the opportunity to do internal shots often, and so it is a bit of a struggle for me. Having embraced the sun/sky system and physical camera for exteriors I’m keen to use them for internals too.
[[/
f-number 8.0
shutter 100
ISO 400
Reinhard burn 0.5
I feel the bright areas are a little too burnt out, but would appreciate any thoughts and tips you can give me. This is a low res test render straight from Viz with no post work.
Thanks in advance,

exponential colour mapping gets rid of burnout normally
Have you fiddled with the gamma settings?
The scene is set up for LWF so there is a 2.2 gamma, and there there is no DaForce style correction curve as yet.
It seems very washed out, maybe you didn’t set up the LWF correctly?
Yeah, something’s wrong with the GI or the lighting as well by the looks of it. The columns should have a pretty strong shadow behind them from the amount of sun coming in but there’s none. And the usual dark corners at the ceiling are actually brighter than the walls next to them (at the upper right above the pool).
r u using the VFB?

Looks like you are using a very bright color (~255 RGB) for the white materials in your scene which is bouncing too much light around. Try backing off all of your white materials to around 175-200 and re-expose so the look “white”. A 255 RGB value for diffuse basically has no absorption which if very unrealistic even for a white material.
Yes I am.
Here is an update, I’ve had to remove the glass from the windows as it was darkening the image too much. As mentioned the irradience map and light cache are currently set very low.
The image does not appear any more washed out than an external image on my screen (which is colour corrected).That is why I will generaly apply the “s” curves in post.
Maybe change the angle of the light? Get some direct light inside the room, that’ll improve both the composition and the lighting inside.
looks realistic to me. That’s how a camera would see the scene.
You need to get some lighting under there, even faked to brighten up the ‘inside’ a lot and then adjust the camera, which will bring the outside into line.
Correct lighting/exposure
Hi,
I thought I would share my 2p worth…
One thing I notice about images like this are that when you talk about the exposure settings for an inside scene. I don’t know if you do any photography with an SLR camera, but I think that your settings could be a bit off for a realistic interior scene. Also, if you are looking towards a window on a sunny day and you want the interior to be lit only with the light outside, you will find that the exterior will appear very overburnt/bright. I think I would actually probably change the shutter speed to be a bit faster so that you darken the image a bit, it should make it look a bit stronger.
The other thing that I think would help this image is changing the GI settings. I have to admit that I am not expert enough to tell you which ones to change, I have to experement, but the shadow bias’s would benifit from a bit of tweeking as you seem to be getting a lot of light leaking around the base and top of the collumns.
The other thing I think would benifit this image is the use of caustics! If i’m not mistaken the sun shines directly onto the water, and that should make some beautiful reflections and refractions on the walls and ceiling.
I wish I could tell you what settings to change, but I wish you all the best.
Thanks for the comments guys, here is an update. Higher render settings with a little post in PS. (please ignor background image…
i think your update looks quite nice but still has a bit of a flat look in places IMHO. I really don’t know what else you can do though..
For example, where the round columns meet the flooring i think i would expect to see a bit of shadow/colour bleed on the floor from the columns - it almost looks like the floor is a standard material?
Maybe the scale of the noise on the pool could be made slightly smaller. I think the result is that the ripply bits are huge, making this seem a bit like a cardboard model instead of a photo. Maybe the pool bottom and side paint/ tiles need to be changed in colour to help add a bit of depth and contrast.
I think you need to make a decision on the background image. Personally i would keep the trees there, but overbrighten it slightly. Purists may tell you to go back to the way you had it originally. I would agree with Cre8tive in that the background would only look like this using an SLR camera if you were to change the shutter speed, but the result would be that the interior would be much darker than it is currently. Personally i would brighten the background a bit and darken the render a bit or add more contrast to it and then consider some artificial lighting.
Its nice but overall i think it still has a bit of an artificial plastic overbright and too evenly lit look to it. Considered not using LWF?
I hope you don’t mind me commenting again, but I think what is realy missing in this scene are some more details, and a bit of colour.
For example, I don’t know too much about pool design, but I think there are usually some sort of water outlet detail all around the pool edge, and perhaps some sort of edging tile that has grouves in it all around the edge.
I think also, you could change the colour of the bottom of the pool so that it gives the water a bit more dynamic.
How about some sort of chrome rail to get in and out of the water?
On a more architecural not, I think the windows are a little fine (the fenistration), and in a pool situation wouldn’t you be able to open them?
Another little detail that as the most pedantic person in the world I would probably add would be the detail of the connection of the collumn to the ground. It looks a little like it was tiled before the collumn was installed at the moment!
One last thing that I think you will have to agree with is that if there were no lights in this sort of room it would be a dark place. Therefore, even if you don’t wnat to have them on, you will need to add them. I think these details will help.
I have to admit that I tend to like a more contrast-full image (I think I just made up a word!!) meaning that I would let the darks be a little darker, and the bright places burn so that you get the feeling that you are indoors looking out.
Don’t forget, when you look with your eyes round a room, and then out the window, the room feels bright, and then the outside doesn’t feel that much brighter. Our eyes are very cleaver little things that change the aperture (pupil in our eye) so that just the correct amount of light hits the optic nerve, making the inside, and the outside look similarly lit, even though one is actually much darker than the other.
I am really looking forward to you updating this one. I hope you manage to make it right.
Cheers,
