I may have mentioned before that I’m not the world best namer of things – I struggle with identification of both flora and fauna, at least beyond the most obvious stuff. This is somewhat odd, since I often recall and recognize in great detail the specific characteristics of things. For example, while I’ve never been able to consistently remember the names of certain wildflowers, I’m very familiar with them and can tell you exactly where to find the plants, when they bloom, and so forth. This is all my preamble to saying that I’m pretty sure these are Ross’s Geese, but that I make no guarantees! From a bit of reading and viewing I did before posting, I found out that telling the Ross’s Goose apart from the Snow Goose is not an easy thing. Some of the differences are more of degree than anything else – one is a bit larger and has a bit larger wingspan. Others are subtle, for example the head shapes. Some or more obvious, such as the presence or not of a certain pattern on the side of the bill. (I now know that some other birds that I had not identified earlier on must be Snow Geese… since I now recall seeing that very pattern and wondering about it.)

Anyway… when we visited the Merced National Wildlife Refuge on an early February evening we got lucky and found a huge mass of these birds (and others) in a location that was fairly close to the places from which viewing was possible. To give you an idea of how many birds there were, when we first arrived we noticed groups of a few hundred lifting off and flying away and began to worry that we might miss the show – but it turned out that a few hundred departures, repeated many times over, did not diminish the apparent size of the monumental group of birds at all!

For me, and I suspect for most who photograph these birds, the “hit rate” is something considerably short of 100%. If I have to wait long enough for birds to fly over, eventually I get impatient and start shooting groups that are really too far away to make good photos. Others look like they are heading my direction, so I compose and start shooting, only to watch them veer off to the side. Others approach close enough but they end up against bright sky and little or no detail is visible in the shot. Others come close but assume odd positions that don’t make impressive photographs, or they may even come too close to photograph! But eventually, something good happens. This group came close, flew towards me, and within shooting distance not only turned to present great profiles but even lined up in such a way that the low sun caught their undersides and filled in what might have been silhouettes otherwise.

Yet Another Reason to Like Live View – Shooting in the Wind

I have posted in the past about some of the advantages of having a live view feature on your camera, especially for the types of photography that I do using my Canon 5DII. This past week I discovered another use, and an unexpected one at that – shooting in conditions of gusty winds.

I most often work from the tripod, and I usually use a pretty large and stable tripod in the context of shooting a full frame DSLR camera. But in some very windy conditions putting the camera on a tripod is not sufficient to stop camera motion and the consequent blur. This is especially a problem when you are shooting in low light or otherwise need to use very long exposure times, and it becomes worse when using long lenses which will catch more wind and magnify vibrations. There are a bunch of tricks that you can try in order to keep the camera steady, but in really strong winds the camera is just going to move, especially if you have a very large lens attached.

One way I try to deal with this is to time my exposures for moments when the wind may momentarily decrease. This can require a lot of patience – sometimes I’ve had to wait several minutes for a very brief halt to the gale, during which I try to make my exposure. But even in this case, you have to make sure that the camera vibration stops completely if you are using a long lens. Ultimately, you have to simply trust that the camera really has stabilized since there is no way to tell directly. Last week, as I was using live view to focus a 400mm lens on a distant subject and again noting that 400mm plus 10x software zoom in live view makes the camera very sensitive to vibration. In the past I have noted this mainly in the context of how darn hard it is to manually focus a big lens this way! But this time it occurred to me that I could use this in my favor.

With the 10x live view magnification enabled, the display is very sensitive to camera motion from the wind. I realized that by leaving the camera in the 10x magnification setup after composing the shot that I could simply watch this display, with its magnification of motion, and wait until the image stabilized during lulls in the wind to take my shots. If the display isn’t bouncing at 10x, motion blur is not going to be an issue. Problem solved. More or less.

Welcome to Visitors from the 5dmk2 Blog

I noticed a spike in visits this morning that I’ve traced back to a reference in a post at the 5DMk2 blog at 1001 Noisy Cameras to yesterday’s post here about Live View on the 5DII. Thanks for the link, and welcome to visitors entering my blog world through the 1001 Noisy Cameras doorway. (And for those who arrived via a different route, if you are interested in the 5D2 and related topics, you should wander on over to the 5DMK2 blog once you finish up here.)

The two points I wrote about yesterday (the benefits of live view for depth of field preview and for shooting with very dark ND filters) are not the only benefits of the live view feature. For example, I earlier wrote about its value when doing night photography, and quite a few of my recent wildflower photos took advantage of it. Before long I hope to write up a more complete article outlining the range of uses for live view.

If this is your first visit to my blog, take a look around. I post a daily photograph (recent work has come from Death Valley and a number of central California locations) and the occasional opinion or news piece. You can subscribe via RSS (link near the top of the page) and members are welcome to post discussion messages.

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