The tunnel is an old symbol for a passage. On photographs they also make good models: Symmetry, interesting shape, often intriguing details.
I love this one in particular. It always reminds me of the fact that even if you do not see the exit and it looks like a dead end, there are plenty of exits to this tunnel – always. Why would there be a tunnel?
Feel free to use this picture in your presentations or any other work which is not for sale.
First impression: The lens is solid, well built and has two rings – one to zoom and one to focus. What makes here stand out from other lenses is a small lever which can also be used to zoom.
It looks like it was thought for videographers: The zoom lever for video, the constant aperture of f/4 through the whole zoom range and finally: The length does not change its length when zooming, which makes it easier to use with matte boxes.
As a photog it was the constant aperture and zoom length which draw me to this lens. From what I have seen until now it could be a good travel lens or even used for portraits.
Actually it is a really big lens. And by big I mean long and wide. Although the filter thread is 72mm the lens feels balanced on the Nex-7. I would say that it is definitely not heavy.
The lens has a wonderful circular aperture which produces the kind of bokeh I like.
I also like the tele end of the lens at f/4. I am curious how the HDRs will work out.
If you want further images you can find them on my flickr stream in the album SELP18105G-sooc.
Contact me, if you want to buy me a coffee 😉 or leave a comment and tell me and the other readers why you would or would not buy this lens.
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.
