I've got a MSc in Electrical Engineering, and I'm currently a trainee at the Technische Universiteit of Eindhoven (TU/e) in a program called Smart Energy Buildings and Cities, where I'm doing a project with NXP Semiconductors.

I love basketball, bikes, outdoor life, travelling, photography, and - last but not least - reading.

Community moderator on Electrical Engineering since August 2012.

comment Measuring pixel / area relative brightness
In Gimp if you select an area (e.g. the face), the histogram will change to represent that area only. You can compare it with the whole picture to understand where it falls

answered Blurry Pictures. Lighting fine.

comment Measuring pixel / area relative brightness
Still, it depends on the composition: take the difference between low-key and high-key portraits. In the first the face is a relatively bright area, in the second the subject is darker than the background

comment Measuring pixel / area relative brightness
That statement doesn't make sense to me. The type of skin influences the exposure metering, but it's the light that actually determines how bright it should be.

comment Why does increasing sensor size necessarily lead to lower silicon wafer utilization?
This question could be a better fit for the Electrical Engineering site. However, my best guess is that, while smaller production can see different devices etched on the same wafer, it's not as convenient for mass production where sorting the different "chips" would add complexity to the machinery.

revised How do popular free RAW editor/converter compare to each other on Windows?
Removed obsolete claim: ViewNX allow cropping images

comment Raw is larger and softer than JPG
@MattGrum Sure, Jpeg supports other sizes than just multiples of 8, but it seems a better reason for rounding than the Bayermatrix, as (AFAIK again) it's a sub-pixel division.

comment Raw is larger and softer than JPG
I'm not sure I agree with the last sentence. AFAIK, the reason why JPEGS are cropped to multiples of 8 is because of the compression algorithm which works on square portions of the image.

comment Do you lose the increased sharpness of not having an AA filter if downscaling?
Disclaimer: the question was dictated by pure curiosity, not that I-m going to buy a new camera just for that :)

comment Can I recover my aurora photographs?
@watami I had the chance to be in Norway earlier this year, and shoot the aurora. I can assure that it's not a trivial thing, unless you get there prepared :) At least you need a tripod and a camera with manual mode; a good sensor is almost necessary if you want decent quality. RAW capturing also helps. It's bad luck that your pictures didn't come out as expected, but you still have the memories :)

@dpollitt consider that many people don't know how to read metadata/exif

@dpollitt whoops, that's the reason for the red pixels. Editing...
