Goes with Cheryl's advice in her article for Aspiring Photographers. I paraphrase: Don't be so focused on the next item of gear. Learn to perfect what you have. More than likely it is already enough.
Welcome to the group.
What a great premise for a group! I'll admit, I do own and use multiple cameras, but only as the need arises, purely for cases when there is something one camera can do that another physically can't. Having said that though, I have always loved the idea of 'work with what you've got 'till it works'. Yes, I've fallen into the "Wow! If only I had one of those!" trap many times before, but nowdays, I'm settled in my gear and love exercising it to get the most out of it I can. Can't wait to be inspired by some of the discussions this group might bring about, thanks for starting it.
So, just to keep the lively conversation running along at a steady pace, I had a thought which could possibly be an extension of the 'one camera' philosophy. I'll be honest, having not actually popped into the group for a while (since I can see no ones posted from the outside...), I had actually come to think that this is what the group was about! So, for discussion, another interpretation of 'One and done':
Does anyone believe/strive/achieve/hope/dream the idea of taking one image and being done? I know I certainly try. I try to get the best composition I can on my ground glass, or in my view finder before I press the button.
Any down sides to this side of the 'one and done' coin? Well, for me personally, I am trying to get that one shot so intently that more often than not, I end up framing the image just how I visualise the final print... which often leaves me with a negative with little to no cropping room. Not so bad on 4x5, but printing a 645 to 8x10 can get frustrating sometimes, especially if the image as I shot it was the one!
