Photos shot with Sony A6300 and Sony 18-135 zoom-lens in Hannover Herrenhäuser Gärten end of August from 21:00 to 22:00 (9-10 pm). It was already very dark and beyond the blue hour when the illumination started. Therefore the images are with stars in the sky and the...
Tulips in Berggarten Hannover (April 2019)
Photos shot with Sony A6300 and Sony 18-135 zoom-lens in Berggarten Hannover in April. This lens is not a macro lens and has no fast aperture. Thus the bokeh is a bit too harsh and the background not blurred out. Still with maximum focal length and closest distance...
Wisentgehege Springe (April 2019)
Wisentgehege Springe in April 2019. Shot with Sony A6300 and 18-135 mm. First time I used the lens. All shots were done with maximum focal length. The shutter speed for the birds in the falconary show was 1/2000s with ISO 1000-2000. Theses photos are thus with high...

Hannover Leuchtet (2018/11)
This photos were shot during the festival Hannover Leuchtet. I used my old Nikon D5100 and Kit Lens 18-105 mm since I do not have a remote trigger nor zoom lens for my new Sony A6300. Most photos were created by using the photo stacking technique to reduce noise and...

Kiesbeet anlegen

Fokusstacking with blue ball thistle (Echinops ritro)
Photos shot with Nikon D5100 and Sigma 105mm f/2.8 macro lens in my garden in July 2018. The focus depth is much too shallow to capture the whole thistle at once. Therefore I tried focus stacking. The focus was manually changed slightly, while...

Hannover christmas city lights (12/2017)
Another attempt to catch the christmas lights in Hannover. This time using an ND filter to get really large exposure times (minutes) while keeping the aperture at normal values (8, 11, 16). People on the streets are thus blurred out mostly.

Owl at flight at a show in zoo Stralsund (06/2017)
Shooting of a flight of an owl at Zoo Stralsund. These birds fly fast and super silent. The problem for the camera (Nikon D5100) is that the shutter speed must be fast (1/1000s), the ISO high enough (ISO 400-800), and the autofocus must be very fast. Focussing is set...

These are the Chilis of 2013. In contrast to previous years I grew only three types and placed them on the balcony. The plants grew 60-70 cm tall and needed to be tied to sticks after the chilis grew to prevent them from falling down. The red ones are hardly hot, but...
Maschseefest 2013

HDR image of the town hall in Hannover
My first attempt with HDR image with the New Town Hall in Hanover at about 23:00. The exposure times, however, were so long (5, 10, 20 seconds) that the leaves are all washed out in the wind and cause ghosting in the resulting image. The second image shows a normal...

radiobuttons in a buttongroup

enable zoom in gui

plotyy with unequal tick locations for both datasets
In matlab the normal way to create plots with two y-axis is to use the command plotyy. This works quite simple, and creates equal tick locations for both data sets: xaxis = 0:0.1:25; y1 = linspace(12.1712,12.7679, length(xaxis)); y2 = linspace(0.3597,-28.7745,...
