This is perhaps a silly point of view, as even film photographers used the darkroom to modify and enhance their images. I guess that the ultimate beauty of an image is something else, it is different sort of achievement than taking the perfect picture.
Digital cameras and software have made it so easy to produce great images that is hard to know what makes a great photograph any more.
I like images of people, and taking perfect pictures of people is challenging. I don't know how you as a photographer can become invisible so that people do not notice you any more. The Ricoh GRD3 is certainly suited to this type of photography. As many people have pointed out, it is small and inconspicuous, and as it is not a DSLR, people don't take much notice. But I think that it would be better if the camera had a viewfinder, so that you could bring it your eye, rather than having to hold it at arms length. I suppose this is why people like to add the optical finder as an accessory. The camera allows you to switch off the lcd for this type of usage.
The optical finders are unfortunately not cheap, and having spent already what I think is a high price for a camera, do I want to invest in a finder? I would be glad to know the experiences of other people who use add on finders with the GRD cameras.
I notice that the rear lcd gets smudged easily. And I have been a bit worried about dust getting into the camera; read somewhere that this is a potential issue.
The lcd shows an electronic level to help you ensure that the camera is horizontally aligned. I find this useful but also distracting as I keep trying to make this thing go green and then loose my framing. You can turn this off, but I will keep it on for now.
