Yosemite Spring Conditions Update

While most photographers in California reserve a part of their consciousness year-round for thoughts of Yosemite (Valley and high country), at about this time of year many think about that location even more. This is the time when the waterfalls really begin to flow and often start to peak as the snow melts at higher elevations, and it is also the beginning of the annual “Great Greening” as plants start to come back to life. In particular, lots of us anticipate the return of the dogwood blossoms.

I’ve been hearing news, and I’ll pass a bit of it along here. Continue reading Yosemite Spring Conditions Update

Wherever We Are Headed, We Certainly Are Not There Yet

Contrary to those who feel that with the introduction of multiple reasonably-priced 20+MP full frame DSLR camera there isn’t much room left for advancement and change, I think that the camera market is still truly dynamic.

One assumption that many make is that the high photosite density full-frame DSLR cameras will “take over” the part of the photographic world previously occupied by medium format (MF) film cameras. Several observations seem to support this notion. The resolution available from carefully used high end DSLRs with the best lenses certainly can compete with that of medium format film, and the arguable advantages of the larger format in terms of image quality would not be enough to convince many to give up the conveniences and lens choices of the best DSLR systems. Even those who might prefer to shoot medium format digital back systems – and I count myself as among those who are interested – are often not in a position to be able to afford the stratospheric cost of the best medium format systems, despite the fact that they compete with large format for image quality.

Some have argued that the costs of the high end systems cannot possibly come down. Some argue (falsely, I believe) that the high costs can not drop because, unlike the costs of computer memory, they are determined by factors that are not subject to scaling. Some argue that the market will never be big enough. However, these folks made the same arguments about the very types of cameras that are now becoming available in the DSLR market – the 20MP and higher full frame sensor camera. Not long ago these cameras cost roughly $8000 and were available from only one manufacturer. They now cost a third of this and are available from at least three vendors.

If you think this cannot happen in the medium format market, perhaps you need to watch a bit more closely. Recently Mamiya introduced a basic medium format digital system (admittedly not one defining the high end of this market segment) at a cost of around $14,000 if memory serves. This week Phase One announced 40 MP medium format backs at cost in roughly the upper teens ($15,000 or thereabouts) range. There are certainly higher priced backs available, but it was only a year or two ago that the 35MP MF backs were the high end – and cost perhaps two or three times this much.

It seems to me that these developments are moving toward bringing MF digital systems to a price point where some who might now get a high-end DSLR system may be able to instead think about going MF.

(Note added later: I just want to acknowledge that I do understand that there are reasons besides pixel dimensions – e.g. number of photosites/MP – to choose MF, and that I also understand that there are reasons other than cost to choose a DSLR. :-)

Article Offers Four Basic Tips for Photographing Wildlife

Joe Decker offers a short list of tips for photographing wildlife, “Four Tips for Better Wildlife Photography,” at the Digital Photography School web site. I’m sometimes skeptical about short “4 tips” type articles, but each of Decker’s suggestions offers good advice that will be useful to folks trying to get better at this genre.

Canon EOS 5D Mark II: Two More Reasons to Love Live View

Yesterday I was at Point Lobos shooting a variety of wildlife, nature, and landscape subject. As I worked I found myself using the live view feature of my Canon EOS 5D Mark II very frequently – partly for reasons I’ve written about before, but largely for two reasons that I’d like to briefly mention.

Much better depth of field preview – Everyone knows about the small depth of field preview button on the body near the lens. Since the lens is open to the widest aperture when you focus you cannot tell what your depth of field will be until you push this button to stop down to the aperture that you’ll use for your shot. There are two problems with this technique: you cannot judge sharpness critically enough across the frame in the viewfinder and the viewfinder becomes incredibly dim if you stop down to small apertures like f/16. Put those two problems together and the usefulness of the preview button is diminished. However, when you use live view the camera automatically adjusts when you press the preview button and the image is still plenty bright to see on the LCD. Even better, you can zoom in to 5x or 10x magnification to carefully check sharpness. All in all, this makes DOF preview a much more useful feature when live view is used.

You can compose a photograph when using neutral density filters to extend exposure
– At one point this weekend I was using a 9-stop neutral density filter to make exposures of the surf with durations in the 10-20 second range. My usual practice is to compose the shot and, if necessary, manually focus without the filter attached. Once the shot is set up I attach the filter. Unfortunately, the filter renders the scene virtually invisible through the viewfinder. Recomposing or manually focusing requires removing the filter, making adjustments, and then reattaching the filter. I discovered yesterday that live view mode can display the image in the LCD even with my 9-stop ND filter in place, allowing me to make changes to the composition/framing or adjust focus without removing the filter

(Shortly after posting this I got a message from B&H photo saying that they again have the Canon EOS 5D Mark II back in stock, and unlike some other dealers they sell it with no markups at the list price of $2669.95.)
