I've been getting many queries about choosing bags for travel for photography gear. The two major domains in which photographers carry their gear on trips are “in-transit,” and during shooting.
In Part I, I discussed the problems of “in-transit” travel, which also affects how you pack for your trip.
In Part II, below, I'll discuss specifications for bags for carrying your gear while “in-transit.”
In Part III, I'll discuss carrying your gear while shooting.
As already discussed in Part I, whether traveling by bus, train, ship or plane, the issues of “in-transit” travel are similar. When traveling solely by car, the traveler is restrained only by the car's capacity and the traveler's personal convenience, so whatever works for other transportation modes, will work for automobile travel.
In Part I you learned it's essential to stow photography equipment in “carry-on” bags while traveling, due to breakage, and liability issues, and the ability to take photos, even while “in-transit.”
There are three general constraints for any “carry-on” bag, including photography gear bags; size, number and weight.
