Después de un años de trabajo arduo, celebramos en compañía de nuestra familia en Cristo, sus grandes bendiciones durante el 2018.
The dreaded wet sensor clean. Things got worse before they got better. Followed a method similar to here.
I picked up a second time my old Konica-Minolta Dynax 5D (an APS-C DSLR see details below) for an extra tour of the warm-humid tropical green houses at the Botanical Garden of Lyon, France.
This time I fitted to the camera its dedicated macro lens Sigma 1:2.8 DG f=50mm (equivalent to 75mm full-frame 24X36 format) . For this tour, I used a CF card 16GB giving almost unlimited number of possible RAW files (1694 !) .
I also used a fix 200 ISO sensor sensitivity. I had in mind to limit the session to 36 images as a regular 35mm film cartridge, but I finally did about 60 … The lens was equipped with a generic Anti-UV protective 55mm filter and its original Sigma shade hood.
Whenever necessary in low-light conditions, I used the build-in small flashlight (NG 12 at 100 ISO) to complement the ambient light and to restore vivid colors. The camera was used either in the manual « M » mode or the aperture-priority « A » automated mode.

After the session, the RAW files were transferred to the computer using a USB multi-memory cards reader and processed in the latest version of Adode Lightroom Classic (LrC version 14.1.1) that uses the external module Adobe Camera Raw version 17.0.1 for the RAW files development. The files were then processed as usual using the regular functions of Lightroom. They are presented either as printed files with frame or the full-size JPEG's.
About the camera :
I bought my Konica-Minolta Dynax 5D (an APS-C DSLR see details below) brand-new in the winter 2005-2006 after using intensively a Minolta Dimage 7 that was a futuristic early mirrorless digital camera. I got the camera as a bundle kit including a AF DT Zoom 18-70 mm / f3.5-5.6 (D) lens, a tele zoom lens AF 75-300 mm / f4.5-5.6 (D) lens, and a very nice macro lens Sigma 1:2.8 f=50mm DG that I used principally for documenting small horological objects.
The Konica Minolta Dynax 5D is a Digital SLR camera announced by Konica Minolta on July 15, 2005. It is also known as Maxxum 5D in the USA and (Alpha) αSweet Digital in Japan. It became available from September 2005 and was bundled with the AF DT Zoom 18-70 mm / f4.5-5.6 (D) lens.
The camera features a 6 megapixel CCD sensor. Image files are created at a maximum resolution of 3008 x 2000 pixels and recorded in JPEG (STD, Fine, EX-fine), RAW and RAW+JPEG formats. It uses CompactFlash for storage. The back has a 115,000 2.5" TFT color display.
Main differences between the 7D and the 5D are:
* Less buttons and dials
* Fibre plastic body, as opposed to a magnesium alloy on the 7D, camera is almost 200 g lighter (970g in workin order with the AF DT Zoom 18-70 mm)
* White balance bracketing
* Newly added colour modes, including black and white
The Konica-Minolta was the last DSLR camera engineering before the cession to Sony of the whole photo camera activities of the company.
The International Symposium on Sensors and Instrumentation in IoT Era, ISSI 2019, took place at ISCTE-IUL on the 29th and 30th of august 2019.

This past weekend heralded more productive work on the robot. Here's the front ultrasonic sensor, and associated mounting bracket.
The decision of where and how to locate a sensor is many times not made until the machine or equipment is actually being constructed. In-house fabricated fastening systems can be expensive and time consuming. Users can save time and money with the universal, modular designed mounting system for sensors from Balluff. In just a few steps, these mechanically rugged standard mounting accessories can easily handle complex positioning tasks.
Sensor de Presión
El sensor de presión integrado, mide la presión del gas. La unidad principal calcula la cantidad óptima de Autogas,la calidad de conducción óptima y el consumo de combustible.

Coloque a foto no Photoshop e use o Auto Levels. As partículas que aparecem são sujeira no sensor da câmera. Um detalhe interessante: minha câmera usa o "sensor cleaning" toda vez que desliga.

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.
Mike Quantrill (pictured) programmed and wrote the software for the system.
Here are the results of a little test. Shot at f32 using my 70-200 f4 L lens (so I know the glass is good).
I get the same spots in the same position as I do on my standard 18-55. And boy is it filthy!
So, I need to clean it, any recommendations anyone?
