most newbies are very scared of flash and say "oh I hate flashed pictures" or "im a natural light photographer". so to that I say, no you arent. its just that u suck at using flash. plain and simple. there is no pro on earth who doesnt know how to use a flash well. if he uses, and how is a different story. so I encourage you to put a lot of effort in understanding flash. once you do, then youll understand light, and understanding light is what photography is (mostly) about. composition and an artistic eye also helps. only when youll know and understand light and how to interpret that in your images will your images take the next step. till then, most are only stuck at the same level of no flash. and you can shoot images that are flashed and dont look flashed if you know how to blend light. ambient and synthetic.
dont want to blow your head with TMI, but, The 560III is a manual only flash. it will work on the camera but you adjust how much light, each and every image. there is no "auto" ttl feature built in. mostly they are used as a off camera flash. I used 3 in weddings set on light stands. I use them for the dance floor, the ceremony, and family formals I use with umbrellas. very fast and very powerful. the 560III also has a radio transmitter slave built in. its compatible with the 602 603 or the new 605
dont know that specific model CTR-301p he mentioned. I use the 622n slaves. I wont recommend a slave till I know what you want it for.what you plan on shooting and what environment.
the 565 is a good flash. doesnt seem to behave well with the 622n as in recent weddings it wouldnt fire at times and have spoken to veteran pros who confirmed it. the 568 (flagship) had a huge price drop after SHANNY (newcomer) came into the scene with what looks to be KILLER flashes.
