You can easily figure out what is causing a color cast in your images with the following list Orange/Yellow Cast - Room lights, Warm White Flourescents, street lamps Blue Cast - Daylight coming into a room, flash when camera set to incandescent, Daylight Flourescent when camera set to flourescent white balance. Green Cast - Cool White Flourescent A flash is blue in nature, since it's set up to 5000K-5500K. So, if you get a blue cast inside it's usually because the camera was set to incandescent white balance. What you might have been seeing was actually a mix of your flash with Cool White Flourescents. The Flourescents would add a green tint that could be seen as a shade of blue. When shooting inside, we are almost ALWAYS in a mixed lighting situation either from incandescents or flourescents. It's always a bit of a problem; but, worse when shooting a large area. So, as I said, it's sometimes easier to join the problem rather than fighting it with either a gold diffuser or a green diffuser, or colored filters. Once you remove the flash from your camera a light from the right or the left, you will begin to see a real difference in your photos. It's nice to see that you have found a tuturial on driving your flash from the D300. I know that you are trying to show the ministry's size and scope; but, I'd begin to focus on small groups at a table or a single person. When showing just a table, say with food items, try to use an odd number of items or groups... like a banana, an apple and a pear. Avoid even numbers of items or groups of items when possible. You will find the images more interesting and appealing. I would now invest in a medium weight Light Stand ($29.90), an umbrella holder ($16.25) for the tripod on which you will mount the SB800 and an SL4000 Softlighter ($49.95). All are prices from Adorama. BHPhoto would have similar pricing. Ritz, online, should have the items; but, at a higher price. Lastly, here are two great web sites that cover low-cost lighting alternatives, including Do It Yourself. Lighting-Essentials.com DIYPhotography.net/ The last time the Annex was opening for photography, we had an amazingly photogenic dog/boy show up. Here is the result. quote:
ORIGINAL: Holdcard Keep them coming. I'm not able to run this latest set of exercises yet. We live in an dingy old 800 sq. ft. apartment (2 adults, 1 person with a severe disability and a 140 Lb. Mastiff, yeah the place is full). I have room at food ministry in the fellowship hall of the church we meet in, but this week there were other issues to be dealt with. I'm filing, and possibly printing all this out so I can get everything out of these lessons. I learn by doing, so you're really helping me at this point. I've experienced the mixing light problem. When I got the D300 all our ministry photos had a blue tint to them. It took me a while, but I think I have the best workaround I can, then look a lot better now. I can't really afford to outfit the whole fellowship hall with color corrected lighting [8|] I"m looking in the book now to see how to use the SB800 off camera, my D70 had it more or less built in and would sync the flash wireless, not sure how the D300 is set up, I haven't been able to set it up yet. Thanks again! Holdcard
