Wish I'd seen this thread sooner. But here are a few tips for anyone else just getting into flash photography:
- Lower shutter speeds (below 1/30th) will let in more ambient light. This doesn't just mean the picture will be brighter; it also means that more colour from the surrounding objects and area will be absorbed by the image.
- Remember most of the exposure in the image will come from that flash, so if you do have a low shutter speed and you move the camera or the subject moves, there will be ghosting/streaky effects. Sometimes you can use this to your advantage to get creative effects, but other times it will look like crap.
- If indoors, aim the flash at a wall or ceiling. The flash will bounce off and give a much more appealing image of the subject.
- If outdoors, a good idea may be to let someone else hold the flashgun from the side so that you can avoid hitting the subject straight on. Use the camera's built-in flash to trigger the external flash.
- Practice. Get to know how your flashgun works both in manual and TTL mode (if it has it). See what effect the various levels of flash strength and your camera's aperture, shutter speed and ISO have.
