Thanks!!! :)
The SONY W35 is a very good camera you will get good results with, however it use only JPEG format from what I know, if you have any setting that allow you to make .tiff or RAW format use it, it is much better and the images have much more information ..
how more pictures with different exposure you do how more final info your HDR will have, this is good for the rendering later so you can control the light from the material room and have night or day light just from one good HDR Light Probe.. work always with 32 bit from the beginning to the end and don't forget about tone mapping of the hdr image , the tone mapping will set the balance of the hdr image on 0.0 EV what is in poser the Intensity 1,000000, if you do that correct changing the intensity to 2.000000 will be like take pictures with +2,0 EV and vice verse..
The final HDR images looks always darker, b/c the monitors use different gamma 1,0.. photographers working on a monitors set with gamma 2,2 so the hdr images looks fine as they should looks like, however everything else viewed on the monitor will be looking to bright.. TV and Monitors have not enough brightens that why using a gamma of 1.0 help to bright everything up but is not the reality, if you look on a painting in real world the gamma curve would be 2,2 ..the picture you take with your camera is converting to gamma display curve to 1,0 what allow you to view the pic on your monitors or TV ... HD TV get close to this reality so about 4 years expect to see the virtual world in different way.. my monitor use gamma 2,2 with a light frame with components used in HD TV so everything looks much more beautiful and sharp and the colors are brilliant.. but still it is virtual b/c even if i print a beautiful picture or render on a paper that have gamma curve 1.0 it looks not the same and i have to change the display curve of my render or image to 1,0 so you can view it or see it printed on paper, so now we need to expect better printers and print papers with new gamma and looking on a picture in the future would be like having a window in your hand.. and that is not more a fantasy.. HDR is the future and new revolution in print and media... and everything just started from a simple mirror ball and a nerd.. ......
P.S Thanks Alex for the sugar!! ::
