I wrote earlier on about my contact with CHDK and how I tried to do some time lapses. I was fascinated how easy this technique is and how powerful the visualizations are. I had my first failures and I did some of them again. I will return to this point at the end.
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:
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.
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:
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:
I love digital tools. Who doesn’t?
Since the rise of the smart phone the use of digital calendars and – even more important – synchronizing them is easier than ever before. And still: The trend to do something analog remains.
