…it is a matter of time and environment.
Noise is your friend, noise is your enemy. Depends on who you are. For a photographer noise is mostly unwanted.
So there are millions of options and tool, how to get rid of noise. The easiest one being reducing your ISO to 200 or lower. This might be OK if you have time and lots of light.
But there are other methods and I was trying out an interesting one: Image averaging.
Averaging is a method which depends on one fact: The noise in the pictures is always different. Basically you take some pictures, treat them and put them together in an image editing program by a special recipe. Each layer gets the following opacity in percent:
100 *1/(number of layers below + 1)
Hence the number sequence starting at the bottom is 100, 50, 33.3, 25, 12.5 and so on. If you want to get a little bit more theoretical background, have a look here at Cambridge in colour (a wonderful site for noobs and pros).
I tried it once with a moving shadow (top picture), which consists of 3 shots at ISO 1600 and one macro with the Yasuhara Nanoha at f/32 and ISO 100 (but longer exposure: 1,6 seconds), just enough to get enough light and not have the wool move because of the warmth of the light. I have the impression it also improved the sharpness.
I will definitely try again with macros.
At the end a small tipp for users of pixelmator: You can add pictures as layers by using the menu only. And the funny part is: You have to add every single picture as one. Red wool consists of 7 pictures… …boring work until the fast guys from pixelmator bring us a new feature 😉
When I saw Sabeena’s alphabet the first time, I instantly fell in love with the forms and colors. I was wondering if I could recreate the same feeling using Blender.
I tried first using only things I can find in Blender and ended up with techno-tourette.
So I decided to start up my old friend inkscape and scanned some curves off the original design of the letter U. I imported the curves back into Blender and extruded them. In order to get the feeling for the paper right, I added a solidify and a subsurf modifier to the whole thing, chose some colors and there you go.
I did not use a texture, but chose a subsurf modifier in addition to the BSDF.
Lesson learned: When you want to recreate complex paper foldings, it might be a good idea to use inkscape for the curves.

On my way back from Bratislava the sky over the Danube showed his best colours. Enjoy.
If you click the pictures you will find Full HD pictures to be used as wallpapers.
All of you who have been to Miniaturwunderland in Hamburg know the little details. One of my favorites was mashed up into a wallpaper. I even created a diver icon for the cows!
If you hear Hamburg you can think of many things: You think of musicals, water, Reeperbahn, St. Pauli, Kiez, Elbe, Alster, Sternschanze, Altona and many more. I especially fell in love with all the reflections and lights. The following picture is made of 4 straight out of camera snapshots, stitched, cropped and finally I added a frame. Enjoy and add Hamburg to your vacation list.
What kind of lenses do you take on a trip to New Zealand? The choices could be many, depending on the camera system. The good thing is that I have a Sony Nex-7.
There are not many lenses for the Sony E mount. That way the choices are not many. I have not many lenses either and chose to take two. The lenses were my two favorites at that time:
- Sony 50mm f/1.8
- Sigma EX DN 19mm f/2.8
You could take millions of pictures in New Zealand. Don’t panic. You do not have to watch them all. I selected some for you and offer a video (unstabilized and ungraded) as a short vacation for you.
BTW: Next time I would go for the Sigma EX DN 30mm f/2.8 and a 18-200 for video. Enjoy.
