Catching a lightning made easy

Motion detection is one of the features most cameras lack. There is some kind of trigger for taking group pictures by waving. But that’s it.

If you own a Canon point and shoot and have already installed the CHDK, you will easily find a script on the CHDK page. I wanted to give it a try, did not change any parameters and started the script on my Canon Powershot S95. I kept the camera on the roof of my car so I could easily blend the layers. After some exposures I finally had three snapshots of lightnings I blended to get this picture:

Thunderstruck

There were also some frames which had no lightning in them, but as you can see I am on a parking near the highway and the camera sometimes interpreted the traffic as a lightning. Nothing is easier on a digital camera than deleting these. I will definitely try this with the 60D and the magic lantern.

Low budget macro photography

Did you ever want to create one of these gigantic macros without cropping your pictures? It is only a question of time until you find mentions of a retro adapter. A retro adapter is a adapter attached to your lens so you can use it the other way around. The adapter fits the end where you use to screw your filters onto. I have a protector for the now open end of the lens.

The principal which comes to use is that…   People who know me, expect at least 1460 words of scientific conundrums and several links to wikipedia and wolfram. Not here! It works. This is all that matters. So I started to have a look at the tips of my beloved aquarel  pencils. They look like this:

Tips of Coloured Pencils

Do you see the problem? The highlights are blown out, because I had the problem with the lighting. You can see the harsh shadows due to the additional light of a fenix LD20 in burst mode. What you also see is the very shallow DOF (see also Two acronyms in photography you should know). So you can imagine the following: Me, trying to focus on the tips of the pencils holding the camera with both hands, trying hard not to breath andgiving instructions to the very patient woman in my life. Please higher my dear, to the right, more, less,….  I bet her secret middle name is patience.

So I searched the web and tried to find the solution for the shallow DOF and here it is: Read more

Two acronyms in Photography you should know

People who look at my flickr stream mostly ask what these acronyms are because they are seen often in photography:

DOF: meaning “depth of field” and providing you either with sharpness in every detail or just a range, hence often called shallow DOF.

The fist

POV: meaning point of view and speaks for itself

Killing field

Interaction of color with picture

One of the biggest advantages of shooting in RAW is that the final version of the picture can look very different. In the examples below I did only use different color profiles for Canon Digital Picture Professional. It is not changing much on light and contrast – obviously you do that when you work with curves – it is more on changing colors and mood.

Have a look yourself. From left to right it is a picture in Velvia-style, natural and retro style.

I really enjoy playing with these styles from time to time. Strangely you can see another effect here: With some pictures some curves do not work. What do you think?

How to create a photograph with a Droste effect

I always was a big fan of M.C.Escher and his recursive and impossible pictures. When I saw the first escheresque photograph I could not resist to search the web and find out how it is done. A few days ago I rediscovered the technique of the Droste effect. A Droste effect picture is a picture within a picture within a picture within a picture… a neverending spiral.

This tutorial is based on the tutorial by Josh Sommers, which is a little outdated so I wrote a short guide on how to do it with current versions of the tools. As the original this version is directed at Windows users.
