I need to achieve a render that best represents a series of LED strips and would look like in a average evening/night setting. I have a few brands to try from, all of which have data sheets. From this data I'm using their cd/m2 values, and have built the strips in c4d as per drawings etc etc. Where I'm "guessing" values, and need advice for, are the display/render settings. ISO, shutter speed, f-number etc.

For example using a value of 7000 nits (cd/m2) is very different depending on what ISO/ss/fn values I put down. I can put some numbers in and get a great looking image BUT I'm not trying to make a pretty render, in this case I need to make an accurate one.

Does anyone out there know what these base values might be? (the display settings that could "accurately"/ best represent these evening shots) BTW the scene scale will be in mm.

Thanks in advance

Thanks Nige - helpful & thanks, but not definitive - I'm getting the feeling that there's no one setting to rule them all. I found this of use => https://www.thearender.com/resources/Ac ... posure.pdf

Your article and the Thea pdf kind-of point me to ISO 400, SS ?? and fstop 2.8, with shutter speed being the wild card, so for now I have it set from between 1 and 1/15 (15secs)

Any more info on this would be greatly appreciated.
