[QUOTE="WayneF, post: 350846, member: 12496"] Using Flash Compensation to adjust the TTL flash level is a good thing of course, and (in the same situation, same room), you should be able to get the first shot right (like you want it), and then the rest (in same general situation, same room ceiling and height, etc) should also be reasonably proper too. In the same general situation, you should be able to shoot as quickly as you wish, after you get the first one like you want it. That said, general metering rules always apply. If you aim your meter at a black subject/background, or at a white subject/background, neither will be correct, or rather, correct is that both come out middle gray. True of ambient or flash, just how reflected meters work. No, not quite correct about ISO. ISO will not adjust to flash level (flash level will adjust to ISO). But ISO only adjusts to ambient level. Which can change as you move around a room, and aim lens at a window or a table lamp, etc. So this changing ISO and changing ambient will shift the flash around (in order to follow ambient, not necessarily a bad thing), but flash compensation or metering will not affect ISO. But I am saying "in same general situation" which rules that shifting out. :) Saying, it will be still be a lot better than if you did not properly adjust the flash compensation. We can also do substantial correction on Raw files later (if we avoid overexposure burning out detail). Yes, the idea of using fill flash with incandescent main light is to use a version of a CTO filter (Color Temperature Orange) on the flash, so you can use Incandescent white balance. There are different shades of incandescent bulbs, and also different shades of CTO (half CTO, 1/4 CTO, etc). 3/4 CTO is a popular choice, and it will knock your flash power down about a stop (to about half). See [URL="http://www.scantips.com/lights/flashbasics5b.html"]Four Flash Photography Basics - Color filters on flash[/URL] I use the swatch book mentioned there, one each of a jillon choices, $2.50. Or the kit mentioned there, a few each of a few popular choices, $8 But you will want to see a few choices. Once you decide your choice, a Rosco 20x24 inch sheet is $6.50 (B&H). I use masking tape to attach them to the flash. I don't use them for matching ambient light, but instead use them to add color to water drop splashes. I think very few non-professional people are willing to bother with this, and it is not my best specialiity either. :) But, it certainly is the conventional wisdom. A more popular conventional wisdom says "Do not mix light sources". :) For tips, search Google for CTO filter [/QUOTE]
