Megapixel Mania – An Extended Riff

I read (yet another… ;-) megapixel rant somewhere online yesterday, and it got me thinking again about the fixation on megapixels as a measure of camera “value,” and the odd and sometimes irrational ways that people respond to this issue. It is well known that over the past decade or more, as digital photography technologies have become more and more prevalent (displacing film in many areas), camera technology has continued to advance in many ways. Among these advances is the ability to increase the number of photosites on sensors of a given size – e.g. give us “more megapixels.”

The responses to this tend to fall into three broad categories: Continue reading Megapixel Mania – An Extended Riff

‘From Film Holder to Memory Card’ at TOP

The Online Photographer (a.k.a. “TOP”) is one of the blogs I follow regularly – lots of great thought-provoking posts show up there on a regular basis, frequently written by folks who know what they are talking about. Take a look if you don’t already follow TOP.

I enjoyed a recent article (“From Film Holder to Memory Card”) by photographer Charles Cramer in which he describes his transition from large format film gear to using medium format digital systems. My favorite example of Charlie’s ironic humor in the post is his “apology” to those who haven’t made the switch: “Note to my large format friends: O.K., I sold out—but I get to use zoom lenses!!!”

In any case, this post is another data point to consider if you happen to be one of those folks who is certain that great photography must be created using traditional film gear and processes. While there is absolutely no question that great work can still be done that way, it is equally possible to do wonderful photography with newer technologies… and, as Charlie illustrates, there are some things that can simply be done more effectively, less expensively, and with better results.

Review: “Light & Land” by Michael Frye

Over the past few weeks I have had the chance to go through Michael Frye’s new ebook, “Light and Land: Landscapes in the Digital Darkroom.” Many are no doubt already aware of Michael’s reputation from his photography, his workshops, and his other publications including his “Photographer’s Guide to Yosemite” and “Digital Landscape Photography: In The Footsteps of Ansel Adams and the Masters.” I have the .pdf version of “Light and Land”, and I understand that an iPad app version may also be available.

It is typical for photographic “how to” books to focus on specific techniques, and to be organized around a presentation of these techniques – perhaps with a section on curves, a section on black and white conversion, and so forth. This approach has its place, especially for certain types of learners and at certain points in the learning process. It is important to understand the basic techniques and operations that are available in the “digital darkroom” of such programs as Photoshop, Lightroom and so forth. That said, the bigger and more important issue is how to call upon these techniques creatively and effectively and appropriately in order to make photographs. Not all “how to” books do an effective job of illustrating this.

Michael’s “Light & Land” takes a different approach, and one that more accurately and realistically reflects the thought process of a photographer who is calling upon this arsenal of techniques in the service of creating beautiful photographs.  He writes:

“The digital darkroom gives us tremendous control over our images. We can make them lighter, darker, add contrast, change the color balance, increase saturation, turn a color photograph into black and white, remove telephone poles, blend exposures with HDR, combine ten images to capture infinite depth of field, or put a winged elephant in the sky.

But what do we do with these choices?” Continue reading Review: “Light & Land” by Michael Frye

More Thoughts About the Pentax 645D ‘mini MF’ Camera

I responded to a post today in an interesting forum discussion about the new Pentax 645D “medium format” (or, as I prefer to call it, “mini MF” format) digital camera. This is a potentially game-changing camera. I has a 33mm x 44mm 40MP sensor and a body-only price of under $10,000. Its cost is far below that of competing mini MF bodies and a fraction of the cost of recent larger MF systems – and the price isn’t much above that of the high end full frame DSLR systems. While larger is not always better, for some types of photographers this puts a level and type of digital camera performance within reach.

In the discussion forum thread I referred to above, a writer had suggested that the 1.7x size differential between the Pentax 645D and full frame DSLRs would not be significant. In a sense he is right – it will not be significant to most photographers, and I surely cannot imagine why anyone would get one in order to make family photos to post on the web. However, I thought I’d share what I wrote concerning why I think that this might be significant for at least some photographers. My response (slightly edited) follows:

Photosite density is rarely the limiting factor when it comes to maximum print size from DSLR originals. As [the other poster] points out, “technique” stuff tends to be much more critical. Enlargement limits are more likely the result of stuff like camera movement, slight mis-focus, lens issues, etc.

I disagree that the size difference between the 24mm x 36mm full frame DSLR sensor and the 33mm x 44mm “mini MF” sensor isn’t significant. There are several reasons I feel this is the case: Continue reading More Thoughts About the Pentax 645D ‘mini MF’ Camera
