Interior white walls and light rebounds

Post by Lal-O » Mon Sep 25, 2017 7:11 am

Hi Guys

Well , as title says .... What do i need to do to get white interior walls and homogenous illumination in my interior spaces? (Just like in the examples below taken from the indigo's gallery :wink: ).

I've tried with the camera settings, light layers ,wall openings and Hdri lightings, but not luck. If the light in the exterior is strong my interior gets darker and get some overxposed (exterior) areas. I know that this effct is correct due indigo is physically accurate , so... it is possible (physically speaking)to achieve those resuls without any tricks,like adding lights and so on ?

I used to be a Vray user (but i got tired of flat and unrealistic images) and i remember there was an option to increase the light rebounds...with this option it was possible to have homogenous lighting, does indigo has an option like that?

Thanks in advance :D

I remember this old trick when taking interior photographs: you make one overexposed (long film exposure), and then another one, underexposed(short film exposure). Then you layer them together in Photoshop, to achieve that homogenous illumination. Did you try using different response functions? Usually with a good hdri map and agfapan-apx-025CD resposne function I'm able to achieve this, but then again, most of the time, I simply apply that old trick.

I'm thinking same thing as our friend the squirrel: vray is not phisically correct, so you can use tricks to achieve what you want. Indigo is physically correct, so you can't cheat. If a room is dark, it's dark and there's nothing you can do with your compact camera to make it look big and extra well-lit.

BUT

if you're a professional photographer you can have reflecting panels, white umbrellas and everything, and you will be able to place them correctly to achieve what you desire. You can also take several shots and combine them in photoshop the get the correct balance between interior and exterior.

Most probably it's been lighten from behind-right, it's visible on left cabinet. If you make interior photographs you also light them with smart placed umbrellas.

Cool !!!

Thanks to all of you for your replies. I'll give a try to everyone's advice given to see which one works best.
The right way would be to do it like in real life ( adding lights, objects etc etc) But it would be a lot of extra work ( which wont make me happy :lol: ) .

Thx again guys :!:

Start by turning up the power on all your interior lights they will light up your room indirectly. I always use Indigo as a sort of light simulation when doing a project. If some areas are to dark it always means you're not generus with the lamps. Another thing is the use of build-in spots in the ceiling. In my opinion a bad decision - they give you a harsh light on people an furniture with unnatural shadows (you're better of with side-light). Use them in hallways, bathrooms or where the light can wash down a wall. In open space use pendels with some amount af light upwards as well as down.

Cheers Nik
