Sigh. Remember the other day I mentioned I had found some sensor dust on my D800. Well, today I got home, where I have the “industrial” size blower and I went to town on the sensor to clean it, and then my worst fears came true. It appears it’s not dust, it may be that sensor oil issue others have found from the manufacturing process (it’s believed the mirror or shutter action flings oil onto the sensor). So tomorrow I’ll have to take steps to get that oil off the sensor. Seems to be a common problem with Nikon’s pro SLRs so I’ll start with a Visible Dust wet cleaning kit rather than put my camera into Nikon’s service centre in Mississauga. Last time I did that with my D200 it took almost three months to get it back and I’ve got photos to take in the meantime.
The photo above is a composite from four images. I took the photos in sequence using the stop down and defocus technique for spotting sensor dust in between. I aimed the camera at my white drapes. Other than cropping out a 6 megapixel image out of the 36 megapixel sensor it’s unmodified from the camera. Yay.

Interesting… I was playing with long exposures at night. I triggered the release and went back inside expecting to get a 5 minute exposure. An hour later I remembered the camera. This is the way it came out - no special effects added here. There was one porch light on, which probably accounts for the yellow cast, and some green leaves where the light was indirect (and of course breezes has moved the tree about in that hour).
What puzzles me is the buildings and fire escapes still have texture ad definition, but the BLACK SKY is all blown out. I wonder what the sensor was up to here...
M.N.Industries the flagship company is one of the fastest growing companies for manufacturing , sales and exports of various textile machineries parts. The company has designed and developed the spareparts with highly expertise and technical knowledge considering the difficulties and problems being faced by the processors in day-to-day operation.
This was a quick sensor experiment involving bokeh. The grain is rather prominent in the bokeh above the Chronicles of Narnia series, which is rather nice.
Unfortunately, worse viewed LARGE.
I tonned down the highlights in this picture with Aperture so that the sensor dust is more visible over the white paper. I've owned my Canon 20D for 1.5 years and will clean the sensor for the first time VERY SOON!
Here's the final product for the shot.
Sensor demonstration using ROHM Group sensors from UV light sensors to hall-effect and motions sensors. Shown at Sensors Expo, June 2011.
You cannot tell, but this was taken about ten a clock last night. 10s exposure. Aperture 16 and ISO 100. And, obviously, camera on tripod.

My A540 sensor seems to be dying; I am getting the Venetian blind effect. Flckr's sharpening agorithm masks this at the small size. Select large and you will get a dynamic flicker from the still image.
8 small blocks that formed a bigger cube, a sensorial introduction to Binomial Expansion (a +b)^2, what we learned in SPM add math.
I don't have the hinged box for this, they come in a tray.Usual wear and tear, a touch of paint will restore them to be like new.
Selling for RM30.
SENSOR SYSTEM
MYSTICAL COMPUTER ENVIRONMENTS
A Mystical, interactive, aesthetic, computer experience.
The Sensor System was used as part of Padgett’s artist-in-residency at Loughborough University with the C&CRS for COSTART, partly funded by the EPSRC Grant GR/M14517 Studies of Computer Support for Creative Work, Artists and Technologists in Collaboration.
8 sensors are located on each side of a 365cm x 365cm frame at 30cm high. The frame is in front of a screen 245cm wide and 180cm high. One person rotates the shape and chooses the colour, one person walks in the frame and extrudes smaller basic shapes.
When people move in the installation squares are generated in the axis they move. Rotation is added and intergalactic patterns result.
This interactive work breaks down the subject/object dualisms as the participant is also the work. Participants move around a sensor system to produce moving abstract designs that are purely aesthetic and join 2D design with a 3D, mystical, inner space.
Airflow and temp sensors on the air box. Looks like the airflow sensor should come out of the box with a bit of pipe still attached. Pipe is 65mm from what I can see.
Looking for a nice enclosed temperature and humidity sensor? The AM2315 is effectively a DS18B20 temperature sensor and a capacitive humidity sensor in a nice enclosure. The enclosed sensors are much better suited to sensing in areas exposed to wind / rain / snow than a breakout board or bare sensor. A small microcontroller inside does the readings and provides a simple I2C interface for reading the finished & calibrated output data.

Bought (4) Infrared LEDs, a 9V, and a pack of Insulated Test/Jumper Leads, and a 9V Battery snap connector to do a quick mock-up of a Wii sensor bar. I mounted them inside some packing foam and wedge it onto my laptop LCD screen. The digital photo picks up on the infrared light. Taken with my camera phone.
Top panel is pre cleaning (two years of dust). Middle is post a scoot with a squeezy pump (mirror up, no contact with sensor). Lower panel is post a wipe with the charged Sensor Sweep brush. All shots are of the same off-white wall at f22 with the contrast turned way up (approximately the same amount).
The results are pretty good and I read around the web that you can spend a fortune on fancy brushes for this procedure. This one is $25 or so, but it really doesn't look any different to a good quality art paintbrush (like a fine sable brush). Most of the defects come off with just a good few blasts of air from the pump so if you don't like to touch the sensor at all you'd probably be OK for quite a while just blowing.
