whites and studios I am shooting with the Canon Powershot G5. I used 1 1000 W halogen construction light reflecting off of my white ceiling. I did a shoot with a mother and child on Portrait mode, tungsten, no flash. Some pics are slightly blurred. Colour ok but white backdrop is kinda grey. If I use the flash it creates a very yellowish cast and lots of hard shadows. I just bought another 1000W light that I will be experimenting with. Any suggestions on how to stop blur and whiten backdrop. I dont think it was a fast enough shutter speed (camera shake sign appeared) should I shoot in Tv or what. Please help me. I am a beginner and am doing a LOT of reading and then experimenting. Any suggestions will help. I would also like to build a studio at some point. Suggestions on wall colours, lights, size etc. Thanks a bunch!

gray whites mean under exposed. slower shutter speed, open the aperture, add another light, faster iso. One or a combination. White areas in any auto modes will lead to under exposure if the backdrop takes up most of the camera view. Need to adjust for that.

Thank you gregory I will try that, but if I use a slower shutter speed will that not cause blurr from children? If I shoot in TV and use a faster s.s. and higher iso 200? and add another light will that work, or should I shoot in all manual. What if I overexpose by 1 or 2 stops? Iam not sure if I am at that level yet. Suggestions?

An example of original was f/4 at 1/60 that was gray and some blur. Double the iso would go to f/4 at 1/125, and then you could do the shooting at f/4 at 1/90 to compensate some for the auto mode reading the white background. Or with original lighting, f/2.8 at 1/60 or f/4 at 1/30. Or add another light so that the original f/4 1/60 goes to f/4 at 1/125 and do the shooting at f/4 at 1/90 to compensate for the auto reading the white background. Or add a light to the background without going to far on brightness, but keep the original f/4 at 1/60 on the subject.

there is another problem at play here too. your 1K lights are tungsten lights with a 3200 degree color balance, your flash creates a light slightly cooler than daylight. An auto balance would correct for the flash and leave the main continuous light looking too warm... to yellow/red. If you want to use mixed lighting in this situation as "flash fill" then in color you need to filter at least one of the light sources to match the other. David
