I have never had a ‘fear’ of two cameras. I have several GSN’s one BW and one colour. Sometimes one 35mm one 47mm camera and both with colour film. Sometimes BW at 200 and one at 400 ISO.
Interesting that you think carrying one of each will detract from your photography. I have never thought about it. One thing I found an interesting comment was regarding BW and colour
you can never truly excel in both colour and b&w photography if you keep going back and forth between them.
The reason for that statement is that when 'seeing' b&w images one focus on pattern, shadows, contrast, etc and when 'seeing' colour one look at complimenting or conflicting colours, colours isolated, etc. Two ways of seeing that is so different so that if one is really intertested in honing ones photographic skills one shouldn't mix too much
One of the things you learn when using media is to do value sketches, these are BW sketches for upcoming colour painting or printing, maybe even photography. So the idea that it is not possible to move from colour to BW and back is a self imposed limitation. I often see shots that don’t work as colour but will work as BW. I carry a second camera for that reason so it’s BW in camera one and colour in camera two.
Bags, no domke because I use a second hand store canvas bag. It carries film, table tripod, cable release and sunglasses. I don’t have a case for my cameras I used Ziploc bags. They actually do the job of protecting. I carry them in my hand, no strap, no nothing.
I also see you have changed your mind about two cameras, you must be getting out more! Good to see you have broadened your horizons. I also would point you to on of our RFF’ers Joe Friday his current byline is ..... “Beware the man who has one gun camera. He probably knows how to use it.” Sometimes solo does give an edge!
