Yes, well, first of all I deliberately pre-empted the ‘weight’ argument by giving an example where I carried both cameras but chose to use the phone. The ‘weight’ argument is well rehearsed and convincing – you take the best photos the camera you’ve got with you, and for spontaneous pictures that’s unlikely to be a heavy device. That’s an easy justification for the camera phone. My point was that there are other shortcomings of DSLRs to be addressed, at least for some photographers.

Sharing – I did concede I wasn’t so convinced by this argument, so I won’t pursue that. (Except to say that while I may not be great at multitasking, I do manage to combine both ‘resting’ and ‘sharing’ with moderate success, and if there’s a lack of 3G I’m learning to respond philosophically to this.)

Editing – no, I’m making the stronger argument that editing (not cataloguing) is easier and better on a multi-touch device than on a Mac. If I’m honest, that multi-touch device is an iPad, but the point remains, multi-touch interfaces knock mouse (or pen/tablet) interfaces into a cocked hat here.

The screen – it’s here that I think you are ignoring the real advantage – for some photographers at least – that immediate feedback can provide for the learning process. Yes, there are those who can take great pictures with film, which they wouldn’t see before they got into the dark room. They know kit, techniques and darkroom tricks so well that they can translate what they see with the naked eye into the finished photograph. We’re digital now, but that’s what you are talking about. Some of us just don’t have that deep knowledge and so our imagination fails us. Feedback on what we are taking at the time when we can still do something about it radically changes to capturing experience. Of course you are right that there are some things that you can change in post production… You can compensate for poor exposure, for example, and with bracketing maybe even for the wrong depth of field. But you can’t recompose a photograph back at home.

And on the final point – to put it in your robust terms – you are wrong! On both counts – on the importance of the sensor – and on being able to do something about the lens. Because unless I’ve completely misunderstood, I can see no way that he can replace the former without also replacing the latter. The point about what I anticipate will be an emerging range of camera accessories for phones is they do let you add better hardware!

However, the one thing you are indubitably correct about it being time for another session Goat Major 🙂
