Trouble with lighting

Postby Gary Puckett » Sat, Jan 15 2011, 12:15PM

Seems I been having trouble with lighting on my renderings. I guess is I have to put so many lights so you can see the detail that it starts to wash out the walls that surround the item.

I have tried not using so many lights but then you have a very hard time seeing the bottom part of the item. I tried using lights to copy what lighting is actually in the real room and that doesn't work at all. I have tried placing the lights further away from the walls nothing seems to work for me. :? Here is an example

If you have any ideas I would greatly appreciate them.

Thanks
Gary

Thanks Kerry, but what the heck am I doing wrong, or has it got something to do with the lighting program?

Gary it is not just a matter of the number of lights it is also where you place them, the intensity settings and the type of light you select. Try for starters turning down the intensity of all the lights you have to get rid of that washed out look. What I sometimes do is put some lights underneath the item to illuminate it, I use something like the "chandelier" which would throw light up not just down, like the downlighter . Once you have got it right you can hide the lights of course so your presentation rendering does not look odd.

Nick,

I may be mistaken but I think all the light fixtures have the same lighting direction affect.

Gary,

I forgot to mention last night that if you want more of the detail under the table top, don't place any lights above it to cast shadows. This is just one light under the top and to the right.

Kerry,

Thanks, but that still is not solving the problem of washing out the walls. Is it just me or do you run across this problem also? Am I correct in that all the light fixtures luminate the same? Also did you get my PM

Gary,

I think you are correct that all lighting effects are down but i think some have a wider beam IE the chandelier.

Nick is correct about using fewer lights, lower intensity.

Be sure to add a shine of no more than 2 to 4 to your walls and floor. You need to add a shine to every texture in your presentation drawing to make it realistic.

Here is a shot with two lights below the table top at right angles with a 30 intensity. I cropped the image to remove the shadows.

If your jpg is too dark, use Gamma correction in Irfanview to correct this.

Hi

Sorry all haven't read the rest of the post since my last reply. i'll have to come back to it tonight and have a read.

Gary have a look in the attached zip file the unedited pic is straight off the job file.

I usually take my pics into picasa and do a little fine tuning, as I have done to the edited pic.

Hope this helps. As I said I'll read the rest of the postings tonight after work.

Bryan
