-I have watched Gordon's DSLR tips video about fill in flash and I understand this but I find the flash puts the subject off and makes there skin tones harsh, how can I solve this problem?
- you can solve the problem with setting down flash exposure compensation for example -1 or -2.
- If you are taking picture indoor with ceiling, you can aim your flash to ceiling and the ceiling will distribute the light around the room.
- the other way is to get a flash diffuser such as omni bounce, light sphere, lumiquest promax system, demb diffuser or a bounce card.
Are flashes a good way of shooting in dark situations, such as people in the night or in dark buildings? Most of the night/dark photo's I see are either taken with high ISO or long shutter speeds.
if you care about the entire frame including background, it is better to take picture without flash, because flash does not have power to light up the entire scene (unless you have very elaborate lighting system).
When shooting photo's of models, why do they always have flashes being used? Why use multiple flashes?
yes, because each flash has a purpose
1. for main light (the strongest, usually covering the entire object)
2. for fill light (to fill in / lighten shadow area)
3. back light for hair and/or background
Indoor, they almost use flash because they are simply not enough light
and general rule of thumb of achieving high quality detailed shot is to shoot in iso 100 or lowest iso your camera has.
Outdoor, flash is used for fill flash (you have watch the Gordon's tutorial)
and then also for catch light (sparkle in the eyes) to make the subject more lively / contrast.
Using filter gel on the flash/strobes and playing with white balance setting could create an interesting color balance and creative photos.
are external flashes much better and worth spending the money on compared to the built in camera flash?
yes, because external flashes are:
1. More powerful
2. positioned relatively higher (so it does not interfere with longer lens)
higher position usually create a more soft shadow.
3. you can direct the light because you can swivel it. (30, 60 or 90 degree). Old trick indoor is to direct the flash to the ceiling and let it bounce and diffuse the light to entire room.
4. Networking and wireless - higher end flash is fully customizable and can set as slave mode. you can build a portrait studio out of multiple flashes with diffusers (umbrellas).
