PhotoNetCast #72 – Apertures, polarizers and GNDs, Portfolios, Brenizer technique and more

Posted in PhotoNetCast Shows on 25-06-2012 | 2 Comments

We have finally decided to tackle the backlog of listener questions we were dragging with us (some already for a few months).

On this episode, Antonio Marques, Dave Wilson and Will Burrard-Lucas discuss aperture, shutter speed and their relationship with sensor sizes and different lenses; polarizers and graduated neutral density filters; some suggestions for the choices that have to be made with online portfolios; hosting and different publishing platforms (CMS); the (Ryan) Brenizer technique; creating packages for wedding photography; and more.

On the news side, mentions of the newly released MacBook Pro and Aperture, and some interesting news coming out of Getty on their coverage of the Olympic Games.

As always, questions or general feedback can be sent via photonetcast (at) or through our contact form.

We are also looking at replacing our long-standing logo on the show. If you have any good suggestions for it, let us know.

Until the next one, enjoy the show…

An interesting episode yet again. Your podcast has returned to the high quality of the originals!

As an addition to the debate about aperture and sensor size is that another factor to consider is the distance from the lens to the capture medium. The larger the sensor/ film size, the further from the lens, and the light fall off is the square of the distance: if it is twice as far then it is a quarter of the light which reaches it. So the small sensor requires a much smaller actual aperture to produce the same f number. The larger format has the lens further from the film plane thus needs a larger opening to produce the same f stop, the square of the distance, which explains why the lenses are so much larger.

Hi Jeremy. Thanks for the comment. We appreciate all the feedback we get, and I do listen even if it’s not so positive. In this case, I’m glad that we are back on your interestingness pool. Suggestions on what we can do to improve are also very much welcome.
