The name is Göran Andersson. I work as a programmer and have photography as a hobby.

  • Canon EF 24-70 mm, f 2.8 L USM
  • Canon EF 28-135 mm, f 3.5-5.6 IS USM

Why the downvote? If you don't explain what it is that you think is wrong, it can't improve the answer.

comment What is a more stable way to lash a mini tripod to the top of 3 tent pole sections?
@RussellMcMahon: A clove hitch is a double half hitch, so with three loops it's a triple half hitch, which you can find references to. Another variation with three loops is a rolling hitch.

comment Missing photos on a roll of film?
Does any of the images look double exposed? Is sounds like the camera did all the 24 exposures, but didn't feed the film for the 10 missing photos.

comment Incorrect exposed images when shooting sports
The camera has plenty of time to calculate the exposure (for example during the eons of time it takes for the mirror to flip up), so the probable reason is that the camera has too little information (too few metering points) to calculate the correct exposure, or that the lighting is too complicated to automatically determine a good exposure.

comment Why my camera shots have a dark area?
If you can take a picture without the lens, and in bulb mode (or long exposure time), you could watch if the mirror flips up all the way, and if the shutter reveals all of the sensor. (Do this where there is as little dust as possible, and out of direct sunlight.)

comment How does auto focus tracking work in DSLRs
@user32334: Yes, you are correct, I misinterpreted the documentation. So, the focusing in SLT is similar to a DSLR in the sense that a mirror reflects light to the focus sensors, but the viewfinder is different as it uses the image sensor for that.

comment How does auto focus tracking work in DSLRs
@MarcusThornton: In an SLT the viewfinder works like in a DSLR, but the focusing works like in a MILC; it doesn't have separate focus sensors but uses the image sensor (or possibly the viewfinder sensor if it has a digital viewfinder).

comment How does auto focus tracking work in DSLRs
@MichaelClark: Yes, the question talks about tracking, but I think that it's mostly about the focusing part. Other aspects of tracking doesn't differ much between the different focusing systems.

comment How to preserve image quality when exporting psd file to jpeg?
@SN: The resolution is just information about how large a pixel is supposed to be in actual measurements. An image that is 1000x750 has the same pixel dimensions regardless if the resolution is set to 72ppi or 300ppi. It's not more printable just because it has a higher resolution setting. If you print it at 300ppi you will just get a printout that is 3.3" by 2.5".

What do you do exactly to set the resolution (ppi) of the image? I can't find any such setting in the export tool.
