I am a little late with my report, but little late than never. During the solar eclipse on March 20th 2015 I took some photos of the event. The results are ok, although I could have done better in my opinion.
I have to admit that I did not prepare very well for the event. I missed buying one of those solar filter foils, which come at a price of 25-30 € for a 20×30 cm sheet. The day before the eclipse (ahem, yes, that’s late) I started looking for a solution and the only thing I could find in the nick of time was a welding mask, borrowed from the workshop at my workplace.
“Unfortunately” it turned out to be an active welding mask. These masks are electronically triggered, meaning the glass only becomes ultradark when a bright lightsource is present. I did not attempt to disassemble the system, so I strapped the complete mask in front of my lens. This worked much better than expected:
I mounted the Tamron 150-600 mm lens on my D800 and strapped the welding mask with a rubber band to the camera. The mask sat stable on the lens, only the rubber band prevented the lens from being locked at 600 mm – the tension pushed the lens back to approx. 460 mm. If I wanted to shoot at 600 mm I had to zoom manually and keep my hand on the zoom ring to prevent it from being pushed back.
That way I shot many images and also made a short timelapse-video.
Here is an unedited image (if you disregard the watermark…):
The sun is green, and no contour is visible. Well, what did I expect. The sun does not have craters like the moon.
Basically I photographed green pac-mans / smileys. On most images the sun is hardly recognizable as such. Through the smeared glass of the welding mask a sharp picture was next to impossible. As mentioned above it was an active mask with a screen which is triggered in bright light. The construction has several layers, meaning several layers of glass, meaning a loss of sharpness.
One detail I could capture though was a sunspot in the upper left corner:
Due to bad preparation the results were not as good as they could have been. However I managed to take a timelapse video and show a sunspot. The main lesson I learn from this shoot is to prepare well (D’UH…) and use appropriate filter media (D’UH²).
Backups are absolutely essential. I wrote about that topic quite a few times already and I can’t stress that point enough. I live a solid backup strategy and it has saved my a$$ multiple times already.
The core of my backup system is a 4-bay NAS system (Network Attached Storage) with a time machine backup (=the content of my computer’s harddrive) and my archive (=everything I do not want to keep on the computer’s harddrive, mostly images). In addition to that there are two identical copies of the archive, which I keep in different locations. Those are “naked” harddrives which I connect to my Mac using a USB 3.0 docking station.
The reason for all that hassle lies in the multitude of sources for data loss. Let me structure this a little. In my opinion the four main sources for data loss are:
Let me explain how my backup strategy covers those risks:
User- or software-related events can be rescued by using the time machine backup I keep on the NAS. If I accidentally delete something, time machine (from here TM) is there to fix it. Same applies if some software runs amok. The little risk which remains is that something happens to TM itself. But for data really being lost two events have to occur at the same time: data loss AND the failure of TM. That is a small risk in my opinion.
Hardware failure is a more extensive topic which requires some sub-points. There are several reasons for hardware to go faulty and each one of those risks can be countered by a different measure.
The risk of physical / electrical damage can be countered by different measures:
The first one is a filter device, which is placed between the wall power socket and the electronic device. If lightning strikes, a fuse is blown inside the filter device which cuts power. That’s much better than roasted electronics.
The second counter measure is described in the point above. If one copy is not physically connected to the power grid (like the backup copies I keep in the drawer), it will not be affected by a power surge. So even if the filter fails and your computer is damaged, you still have the separate copy of your archive.
The pinnacle of data protection is protection against major catastrophic events.
I am talking about a fire, burglary or a flooded apartment due to a broken water pipe in the walls. In that case only an off-site copy of your data will save you. That is why I have two identical copies of my archive (the naked HDDs in a plastic storage container). The first one is stored in a drawer at home, see above. The second one is stored in another house. You might deposit the HDD at a friend’s house or at work, if that is an option. That brings some hassle as you have to collect and bring back the HDD for the next archiving session, but if you are willing to go the extra mile for extra security, that is what you have to do.
– Backups are essential, protect your data !
– Redundancy helps you to protect against multiple risks
– Choose for yourself which risks you want to protect against.
At the evening of March 22nd 2015 I stepped out of the cottage where we spent our vacation to take out the trash. When I raised my head I was awarded with an astonishing view. Moon and Venus were in conjunction.
Enjoy the images, like, share !
I wrote another lens review for nikonrumors.com and it just has been published. This time I take a closer look at the Venus 60mm f2.8 2:1 macro lens. The lens has a maximum reproduction ratio of 2:1, which means that the image on the sensor can be twice as large as the actual object. Definitely an interesting lens which can produce sharp images, but it is not easy to handle.
Here are some sample images made with that lens. Please visit Nikonrumors.com to read the full review (link above).
There are many different philosophies and solutions when it comes to storing one’s camera gear. Since the hunter-gatherer blood runs strongly in my veins I amassed quite a collection of gear over the years. After some interim solutions with shelfes and boxes I finally decided on a dedicated IKEA Billy shelf with glass doors for storing and organizing my photo gear, see this post from 2012.
Since then equipment and accessories cluttered the shelfes and what was once organized turned into a chaotic heap. Between Christmas and New Year’s Eve I sifted through my gear to get rid of equipment I rarely used.
Along with this screening process I installed some LED lighting on the shelf. I bought two sets of IKEA LEDARE LED lights. One set consisted of four LED spots while the second set contained four LED strips. I chose the IKEA lights because they were the cheapest and have a warm color temperature of 2700K. There are also variants of the LEDARE lighting set which contain coloured LEDs and a control panel to change the color. I decided to place the spots on the shelfeswith lenses and cameras, because those are the core components of photography. The LED strips add a little more ambience to the shelf, so I installed them on the “flash shelf” and the “auxiliary photo stuff shelf”.
At first I punched a hole into the back lining of the Billy shelf. I used a drill bit and manually rotated it to create the hole. The reason I did this manually is that I wanted more control over the process. Since the back lining is very thin an electric drill would have punched through in a second and also damaged the wall behind it.
The spot can either be installed with adhesive tape or screws. I chose to employ the adhesive tape. Then I threaded the wiring through the hole in the back and plugged it in. A package contained four spots, I installed two spots on each shelf.
The LED strips consist of X white LEDs, encased in clear glass casing. Connectors which come with the set can be used to either have four separate strips which can be placed individually or they can be connected to a longer strip.
I opted to make two longer strips out of the four elements. A hole was punched into the back of the shelf lining as described above. Again the strips were installed using adhesive tape. I bundled the cables at the top of the shelf, organizing them with cable binders. To have easy access to the switched I taped them to the side of the shelf. All that was left was to lay a cable channel for the power chord and there we are !
Today’s Lumenatorial covers how I captured the photo of that baby ladybug. The story begins when I drove my car through the car-wash. Back home I inspected the cleaning job and found the ladybug on the car’s roof (however it got there at temperatures around zero). I took it inside and quickly assembled a makeshift studio.
An old film roll served as a holder for a matchstick on which I placed the ladybug. Two SB-R200 flashes with diffuser panels provided light. I mounted the Venus 60 mm f2.8 macro lens on my D800 and put the lens into macro mode (2:1 magnification !). The image was taken at 1/200s and f8, ISO 100 (don’t get fooled by the metadata. The lens is fully manual, no information is transmitted to the camera. The standard setting f2.8 is written into every picture’s metadata.The ladybug crawled and down, back and forth. I took around 80 shots during the session and chose the one at the top to be the winner. The grey blurry spot in the background was not intended, but helps the image. It is actually a reflection from the frame of my iMac which stood about 30 cm behind the ladybug.
Post processing involved stamping away some sensor dust (“a dirty mind posesses a dirty camera” or how did this saying go ?).
As a bonus here is a 100% crop of the final image. Not so cute at all, that ladybug, eh ?
A few months ago I wrote about the re-organization of my workspace. I purchased an electrically actuated desk, assembled it by myself and re-arranged the messy wiring I had produced over time.
Shortly after New Year’s Eve I received an email from the company which produces these desks, Inwerk. It was a standard email asking if I was satisfied with the product, if I had any questions etc. I replied with a few lines saying everything is ok. I also gave them the link to the article I wrote, which also contains a video.
Nothing happened for two weeks. One day my wife called me at work. “A package has been delivered, it is quite heavy and a sticker reads ‘caution, glass’. What did you order ?” I was baffled, because I did not expect anything. The package turned out to contain a bottle of wine and a short note from the sales agent at Inwerk. He told me that they enjoyed the video and wanted to say thank you with the bottle of wine.
That is an oustandingly kind gesture and made my day. Very good customer relationship management, thank you Inwerk !
Here is the video I sent them, enjoy !
