Weekly water change today. New full tank shot as well. I arranged live rock and tried to glue green ricordea florida onto rock, but it escaped again:). Tanks scape need little bit work (center tall rock needs to be split and re-positioned). Camera used Nikon d810 with 105mm macro.


Order from whitecorals.de

New inhabitants arrived from White Corals few days ago.

  • Zoanthus Radioactive
  • Ricordea florida Red
  • Ricordea florida Teal
  • Acanthastrea Hippie Flavour
  • Zoanthus Southsea Flamethrower (very nice and bright colors as seen in first picture)

Tested new camera (Nikon d810) and had few problems to get sharp images (learning curve). Have to try again tomorrow :).

Stack or not to stack

I have been playing with zerene stacker (http://zerenesystems.com/cms/stacker) few days. It is a focus stack program which lets you stack of images to one sharp photo. It works quite well with static subjects but moving object is harder to shoot. But here is one sample (unedited) which shows difference between stacked image and normal photo. 

As you can see there is motion blur due the coral movement. So I have to try to get more light and shoot faster. I used 5d_Mk2 and magic lantern for getting focus stack without focusing rail.

And here is another example with static subject (single shot and another stacked of 32 images).

Another try with Helicon Focus (http://www.heliconsoft.com/heliconsoft-products/helicon-focus/) which seems to make little bit better stacking. I think I will stick with helicon on near future.

Arduino led controller sunrise video

Diy arduino Led controller sunrise test video. Maco timelapse of zoa corals wake up.

The sunrise starts from zero and will add 7% power to Royal Blue leds and few % for white leds. This happens in two hour period. After that the other leds will be ramped up (Royal blues: 63%, whites 55% and Green and Cyan to 51%) in one hour time. Then leds are kept in these levels 6 more hours and then system starts to leveling them down (same way as sunrise).
