Hiya Rob,

Another great podcast mate, really enjoyed listening.

Firstly congratulations again on the book cover and as far as not being paid, who cares? To have something like that in your portfolio is a wonderful thing, it could easily be terrible wedding shots that were paid for and I'd rather see a free good shot on a book cover than terrible wedding shots no matter how much was paid.

Your experience is really shining through and it's nice to hear your own take on the often mistaken technicalities of photography. You've seen for yourself the effects obtained from closing the aperture and fully understand the increased exposure time and how that really affects your image sharpness. The amount of times I hear technical mistakes in the shop would drive you mad especially explaining that their big zoom lens allows for example 1/125th wide angle but plummets to 1/30 at full zoom. Then trying to explain that even with IS/AS etc. they're trying to handhold a full zoom at 1/30th and that's why the image is blurry is really quite exasperating. (Typically if the customer thinks the camera, lens or even you and your store are the cause of such a mistake!!)

Really loved your addition concerning pixel and sensor size with the difference of DOF, a compact camera usually doesn't stop down to such apertures as it really doesn't have to. Another fine example of the experience you've gained.

Admirable stuff Rob, the technical gumpf has gone in, your experience shows the actual reality and the final picture is more important than any pure technical details can ever be.

All the best,

Hi Victor!

How are you doing? Must be great to have your camera back after its Holiday!

Thanks for your comments, I really appreciate them - I felt I was rambling a bit on this one, I was a bit too tired after a long week at work!

Anyways, hope all is well with you and yours,

Cheers, Rob.
