Travelling by air, or coach, means minimal luggage. The 'air.txt' file looks directly at a couple of aircraft related topics, but, in general, the problem is one of space. You will be likely to want to carry more gear if you are going to Florida than to Spain - I find there is MUCH more to photograph in Florida, but you must still use common sense. Lets look at Florida, both 21 and 14 nights. My wife took her zoom compact with plenty of film and a spare battery, which also fitted my SLR. She actually used 15 rolls of 24 exposure film in 3 weeks and 8 in 2 weeks. The video camera was carried in a large make up purse, NOT it's own bag - size and security. Plenty of tape and charging lead. Over 9 hours of video was shot in 3 weeks and edited later. A tip here - American 8 mm tapes, and I ASSUME 'VHS-C' tapes fit our cameras - forget the PAL issue here, mechanically the cassettes are the same. It may say 120 min. on the American tape, and you will only actually get 90 min in a PAL camera. The fact is that tapes, when I was there, were over 2/3 cheaper than if bought in England !!! Colour still film was less cheap, but still cheaper. Processing was VERY expensive in Florida. The carrying of the video was shared. For 'serious' stills I took a Canon EOS 600 body with 35/135 and 100/300 mm ultrasonic zooms and a 300TL flash - meant for a Canon T90, but it works perfectly well on the EOS. Spare batteries and a POLARISING FILTER, which was used a lot. I took 15 rolls of colour slide - Fuji - and 20 rolls of black and white. I used 12 slide films and 15 B&W. Films were sometimes changed mid-roll - the Canon can be programmed to leave the film leader out of the cassette, and an important part of kit, always carried, was a black marker pen. This was used to write the number of pictures taken on the leader of a film removed from the camera. On reloading that film, the lens cap is put on, the camera set to manual and the autofocus switched off. The smallest aperture and fastest shutter speed set and the shutter fired until the right number shows on the counter. ONE extra exposure prevents any danger of overlap and the controls are returned to normal. With care, and a leader extractor, this can be done with a compact by covering the lens with a cloth, but not the exposure senor, when reloading. All tripods, monopods, etc were left at home. Many people may not need the 100/300 or equivalent - but I am keen on natural history and then, in a place like Florida, such a lens is very useful.
