Earlier this year, I visited a show of tropical butterflies. It was cold outside and way too hot and humid inside. However, the water drops dripping about everywhere made for some really nice pictures with the colorful butterflies:

Notice how the narrow depth of field draws your eyes to the eyes of the butterfly. I feel as though it will dip into the drop of water for a quick drink before taking off again.

Unfortunately, I did not take any notes and I can not find the name of this wonderful little critter.

For the technical minded: the picture was taken in available light at ISO 400, 1/80s, f/2.8. It would interest me to see how the image would look at f/4 or even f/8 with increased depth of field to include the butterfly wings … next time. 🙂

Freising is having it’s 80th annual fall fair this year and the town celebrated the last day today with some spectacular fireworks:

In case you are wondering, it is actually quite easy to make this kind of photo if you know what you are doing:

  1. Set your camera on a tripod and use a cable release or a remote control (infra red remote, RadioPopper, PocketWizard, you name it) to trigger the exposure. I use a simple remote control cable.
  2. Turn off the auto-focus and manually focus the camera (usually to infinity). This is faster and more reliable than having the AF hunt the night sky.
  3. Crank up the ISO as far as you are willing to live with the noise. For example, on a Canon 5D, ISO 800 is great and ISO 1600 is acceptable. A Nikon D3X will go even higher, as will a Canon 5D mark II. A pocket digicam will probably struggle at ISO 400 and above. Experiment – preferably before the big event.
  4. Use manual exposure mode and open the aperture as wide as it will go.
  5. Still in manual exposure mode select a good exposure time. I find that between 1/125s and 1/8s works well.
  6. Expose at will and enjoy the show!

I usually use the camera screen to judge exposure. That is, I set the aperture wide open and shoot at whatever exposure time I have guessed. Usually 1/60s is a good place to start as any.

It is normal to see some blown highlights in the middle of the explosions and at the back of the rocket engines. Because of this the histogram and the blinkenlights are useless. Instead, ensure that the night sky is black and that the fireworks are clearly visible.

If the sky is too light, shorten exposure time and/or reduce the ISO. Similarly, if the fireworks are too dark, lengthen exposure time and/or increase the ISO.

Once I have set up the exposure correctly I point the camera at a likely section of sky and snap away. Since the exposure will not change, I only change it to get a different effect. There is no need to check every image.

In fact, I simply snap away until either the fireworks stop or I grow tired of taking pictures. It’s a good idea to have some spare batteries and memory cards on hand …

That’s it. Have fun!

Last weekend I came upon this dragonfly while walking along the Große Laine in Jachenau in the Alps.

The dragonfly zoomed about over the water of the river for a while before landing on the face of a large boulder to spread its wings and enjoy the warm sunlight. I was able to get consecutively closer to take some pictures before a child popped up over the top of the rock, peering straight down at the dragonfly. This, of course, was a bit too much for the dragonfly, which took off.

I really love the comment of the child: “I guess it thought I was going to kill it.” – Spot on, dear!

While out walking I spotted this Small Tortoiseshell Painted Lady butterfly sitting on a purple lilac:

For some reason, lilacs seems to drive butterflies in general and these in particular into an ecstatic frenzy: the butterflies come from all over, congregate on the blossoms, and flutter about as if delirious with pleasure. I guess the nectar from the blossoms is really, really tasty.

Photographically speaking, the image was quite a challenge to obtain: I was carrying only a Canon G9 at the time, so I had to get quite close to the butterfly to be able to photograph it. And even though the butterfly was having a really good meal, it clearly did not want to become a meal for someone else – so it was moving about at a brisk pace and did not allow me to get very close at all.

I cranked out the zoom all the way and held the camera at arms length, which at least allowed me to get close enough to get a significant part of the frame to show butterfly, not background.

The problems did not end here: when cranked out fully, the G9 is at f4.8 and the late afternoon light was not bright enough to allow a short enough exposure to freeze the butterflies motion at ISO 80, which is the lowest ISO the G9 will allow. (I usually use ISO 80 to reduce noise to the minimum.) In this case, I decided that noise would be less of a problem than motion blur and set the ISO to 200 to allow a 1/320s exposure.

The result is adequately sharp. If you look very closely, you can tell that sharpness begins to drop off near the butterfly head. Just a little bit softer and I would have tossed the image – I guess that having a small sensor (and therefore great depth of field) was good in this case.

Update 06-MAY-2010: Reader J Danson kindly pointed out that this is not a Small Tortoiseshell but rather a Painted Lady. He’s right, so I’ve fixed the posting but have left the URL intact.

The garden spider or cross spider is one of the more common (and quite harmless) spiders that builds large circular webs. This one is a european garden spider or diadem spider (Araneus diadematus) which my daughter found in our garden:

In this image, I like the way the sunlight shines through the lighter parts of the spiders body, making it appear that the spider glows from within.

As I was watching the spider and photographing it I saw it catch three small flies in its web. I guess that pretty soon this spider is going to be quite a bit larger …
