Meadow plants bend beneath the weight of an early October snowfall, eastern Sierra Nevada, California.

I made this photograph on a very cold early October morning high in the eastern Sierra after a series of early season snow storms had passed over the Sierra. The gravel road to North Lake had apparently just opened again on the morning I arrived, and few other people were there. I was there to photograph autumn aspen color, but the opportunity to photograph snow scenes so early in the season distracted me.

As I walked the road skirting the edge of North Lake, I passed by meadows that were completely covered by new, untouched snow. Here and there a few small plants managed to poke up from beneath the white blanket.

Merry Christmas and Happy New Year!

Tripods and Shooting in High Winds

I recently saw – and replied to – a question posted in a photography forum regarding tripods and shooting in high winds. The poster wrote something very similar to the following:

I realized that many shots from a recent trip are blurry because of wind shaking the tripod. Even hanging 10lb weight did not help. So now, I am looking for a new tripod that won’t be affected by wind.

What the writer has discovered is that no tripod is immune to strong winds, especially if you make long exposures and/or use long focal length lenses. Even if you had an absolutely rock-solid tripod, in a 40 mph wind your camera and lens will vibrate enough to create a slightly less sharp image.

So, what to do? You could get the heaviest tripod you can find and weight it down with bags of rocks and what not. But then you are stuck hauling around the dead weight of this tripod the other 95% of the time when you don’t need it.  Yes, get a good solid tripod and a good head with good camera brackets, but other things can help in high winds and, in fact, may be necessary even with the best tripod:

  • Use a shorter focal length if possible.
  • Use a higher shutter speed, even at the expense of a higher ISO, larger aperture, and accept the slightly increased noise or slight loss of DOF.
  • Consider using image-stabilization (IS) even with the camera on the tripod in extreme conditions.
  • Don’t extend the tripod legs all the way – if possible shoot from down low to the ground with the legs retracted.
  • try to brace the tripod against something – rocks, your legs, anything that will dampen vibrations a bit.
  • Try to use natural wind screens when you set up – sometimes being in the lee of a wall or tree or rock can diminish the wind enough to make a difference.
  • Time your shots for moments of less wind.
  • If your exposure times are not extremely long, gently resting a hand on the lens or camera body can dampen the wind-caused vibrations.
  • Rather than relying on a single exposure, make many redundant exposures – some will likely be less affected by the wind than others.
  • If you have a strap attached to your camera, take steps to make sure it doesn’t flap. Wrapping it around the tripod may be sufficient.
  • If conditions permit, consider removing your lens hood.

I recall once shooting on top of a bluff at the far reaches of Point Reyes, normally a very windy place and on this day windy enough to almost be scary. But the light was beautiful and I wanted to make photographs from the edge of the bluff. I ended up retracting the tripod legs so that the camera would be lower to the ground, sitting with the tripod braced between my legs, using IS, leaving a hand on the camera to dampen vibrations, raising the shutter speed, and making many exposures. In the end, a good percentage of the images were adversely affected by the wind… but among them were some good ones that were sharp.

An Itinerant Photographer and His iPad: A Second Report

Some time ago I posted “An Itinerant Photographer and His iPad: A First Report” – and this is a follow-up to that post, written after a few more months of experience with the iPad. It is also an expanded version of something that I posted in a photography forum in response to a question about using the iPad as an image backup device.

One question that seems to come up a lot is whether it is possible/viable to use the iPad as a backup device for making copies of your files in the field. There at least two reasons that you might want to copy your files from your camera’s memory to an external storage. First, you may want to create duplicate backup copies of the image files on your camera memory cards for safety reasons – it is risky to have only single copies of them. Second, some might choose to do this so that they can economize by using a single memory card, transferring files from the card when it is full, erasing the card, and starting over again. I’m not convinced that this makes a lot of sense given the relatively low cost of memory cards today and the risks of having only a single copy of your files.

You can transfer raw files directly from your camera to the iPad using a USB cable and the “camera connection kit” adapter. Here are ome observations based on my experience doing this:

  • It works – you can move your raw files to the iPad and view them there.
  • The process is very slow. Thumbnail previews appear quite quickly, but downloading is a very long process during which I usually find something else to do.
  • You need to think through the memory issues carefully. Your raw files are quite large and the maximum memory in an iPad is currently 64GB. I have the maximum in mine which leaves me about 32GB for photographs. (I have a lot of music and video files on my iPad – perhaps more than the typical user.) There will be very little space for photographs if you get the 16GB model and the 32GB might be tight depending upon what else you store on it.
  • You can view the raw files directly on the iPad. They are not optimized – and raw files need some sharpening and so forth to look their best – but they are fine for previewing images and sharing with others who might want to quickly see what you came up with. Don’t underestimate the value of being able to share files this way. I notice that sharing the images with others on the iPad is often a more natural and pleasant experience than sharing them on a laptop – viewers will frequently hold the iPad and pass it to one another in ways that are rarely seen with laptops.
  • The raw files cannot display at full native resolution – there is some upper boundary currently built into the iPad – though they do  display at a resolution that is considerably larger than that of the iPad screen.
  • I may be missing something that would make the task simpler, but I don’t find it very easy to delete the files from the iPad once they are transferred to my computer.

A bottom line is that you can use an iPad for backing up files in the field, but you need to be aware of several issues before you decide to depend on this. The issues include the very slow file transfer speed and the importance of making sure that the unused memory on your iPad is sufficient for the files you will transfer. With a 64GB iPad, the vast majority of users will have more than 32GB available.

(If the speed and storage space limitations of the iPad are a problem for you, there are other options for backing up in the field. There are specialized back drive products that are designed for making backups of your camera memory cards, or you could use a regular laptop. The tradeoff its greater storage capacity and access to more photo editing applications include shorter battery life and greater size/weight.

What about image editing on the iPad? Several programs are available the provide varying levels of image editing capability.  I use Photogene. It is competent and well-worth the very tiny cost. It provides basic editing features that can let you create decent (but not stellar) jpgs for upload. It does a curve, cropping, black and white conversion, color adjustments, simple sharpening and so forth – but it most definitely is not Photoshop or Light Room. That said, I’ve used it for doing quick edits and web posts from the field. For what it is and for the very low cost, I recommend it. (iPad apps appear so rapidly that it is quite possible that other options will be available by the time you read this.)

Can an iPad replace your laptop? The iPad is only sort of a laptop replacement – I like to simply say that “an iPad is not a laptop,” though it can perform some tasks that you might otherwise use a laptop for. It is great for web browsing and OK for email, though extensive typing on the virtual keyboard is awkward and error-prone. I am fine with it for short emails and short web posts and reading the updating social media sites. You can do better with an external keyboard, but this starts to defeat the small size/weight and convenience of the iPad and makes a laptop look like less of a burden.

Battery life is excellent. Apple is not lying when they claim 10 hours per charge.

The tiny size and small weight make a significant difference. Even my small laptop seems downright large after carrying the iPad instead. It is small enough to easily slip into a side pocket of my camera bag when traveling. I left the laptop at home and carried only an iPad on a weeklong trip to New York City. I was very grateful for the size and weight savings and only mildly inconvenienced by missing some of the power of the laptop I would usually take. What with tripods, lenses, bodies, flash equipment and other gear, I welcome the smaller size/weight of the iPad when a regular laptop is not really needed.

One other reason to have an iPad is that publishing is likely to move increasingly to forms that can be distributed on devices such as the iPad. Photographers would do well to experience and understand this first hand, especially if they intend to distribute their photographs electronically and/or write about photography.

VERDICT:

It will make sense for some photographers and some circumstances, but not for others. There is no universal “right” answer to the question of whether the iPad is a useful tool for photographers – the real question is whether its features will or will not be useful to you. For my part, when I don’t have to do more than minimal editing in the field and I want to share electronic versions of photographs and travel light… I prefer to take the iPad rather than my laptop.

An Itinerant Photographer and His iPad: A First Report

I returned last night from a week-long visit to New York City. While this wasn’t just a photography visit, enough photography was part of the plan that I had to carry a reasonable amount of equipment. Typically I would bring along my Macbook, but this time I decided to leave the laptop at home and see if I could get by with just an iPad instead.

I knew that this would necessitate some compromises in the way I usually operate on the road. For example, serious photography applications like Photoshop and Lightroom simply don’t run on the iPad, so there would be no possibility of doing real post-processing work on the road. The iPad doesn’t have a “real” keyboard, instead providing an on-screen “virtual keyboard” – more on that below. On the positive side, the iPad is positively tiny compared to any real laptop. It makes my 13″ Macbook seem terribly bulky by comparison. The iPad slips easily into the external pocket of my Crumpler Eight Million Dollar Home camera bag, and doesn’t add enough weight to the package to be worthy of note. The battery life is tremendous and the charger is very small.

What follows is an early report on certain aspects of iPad use by the traveling photographer – or at least this mobile photographer. Continue reading An Itinerant Photographer and His iPad: A First Report
