I'm taking an Alaskan trip later this month and intend to do some whale watching. My D3400 takes excellent pictures AND excellent video. Problem is it can't do it simultaneously. In this once-in-a-lifetime moment, which mode do I use to capture the moment? Thanks
My wife and I have been to Alaska three times, the last being about a month ago. Each time I went on at least one whale watching tour, and each time we saw whales and had some opportunity for photographs. I used a Canon dslr with 100-400 zoom lens, and got a few decent shots, though nothing like what was possible if I had been a more experienced and accomplished photographer. Looking back from my present point of view, I think I would opt for using a camera that allows shooting 4k video with the option of snipping 8mp stills from sections of video. I understand that Panasonic has several well regarded cameras which will do this--the models zs60, FZ100, and FZ1000 and FZ2500 come to mind. I also believe that the SonyRX10iv will do this (it can do just about everything, it seems).
If you should decide to go that route, you don't have much time to prepare. You definitely wouldn't want your first experience with such a camera and procedure to be when whales are breaching around your boat.
If you have not already booked your whale tour(s), I would recommend going with a small boat that takes only a very limited number of persons, say, not more than 12 persons. On the larger boats (I have been on both types) that carry several dozen, up to perhaps 100 or more, you can be sure that people will get in your way, whether intentionally or not. While the larger boats can likely find the whales--my impression is that they all share information, or listen in on the traffic of other boats that have spotted whales-- your shooting can be limited by the larger numbers of people.
Also, keep in mind that you have limited "time-on-target". The average duration of a tour is on the order of 2 or 3 hours, with much of that time spent in "going out" and "coming back". The time spent in the vicinity where the whales can be expected may actually be only 45 minutes or less.
Also, the speed of the whales must be factored into your planning--they are deceptively fast. A particular sighting which is photo-worthy may last only about three seconds, if that much. When photo opportunities are presented, one must seize them, because second-chance opportunities are very limited. I think this factor makes for an argument in favor of continuous recording via video.
In any event, you will no doubt have a great trip. Best of luck!
