In discussions of film vs digital, it is occasionally stated that digital needs to be 20MP or 50MP or some large number in order to match the (low-modulation) extinction resolution of film. Your...

Not sure what you are saying with the plots. Yes, an ideal brickwall lowpass filter would set harmonics > N to zero and not affect the others. Interestingly, ideal lowpass filters assume that you...

I think there are two takes on this: 1. You are a general camera user, and you want to find out what camera best suits your general usage. 2. You are a camera nerd and want to figure out how to use...

By "develop" most people would think of white-balance, color correction, tone curves and such. DxO does not seem to apply those things, as the measure things that are found more directly in the...

Its been a while since I read that paper, but could it be that the second derivative at DC just "happens to correlate" with the perceptual characteristic that we are interested in? I.e. there could...

I have no problem with people wanting to make money. I have a problem when their products benefit vs cost ratio is worsened. In that case, I will make my opinion heard. -h

Use your intelligence to investigate what physical carrier is used by 3G. Hint: not satellites. 3G coverage is good in towns and along highways in my country. 3G coverage can be poor or...

Even USM is non-linear (description from wikipedia): "The same differencing principle is used in the unsharp-masking tool in many digital-imaging software packages, such as Adobe...

What good would a Wi-fi dongle do me if there is no internet access to hook it up to? If Adobe goes bankrupt I might like to be able to read my 40.000 files. My kids might like to be able to read...

Imagine how happy we non-US customers are to have to watch those silly threats, knowing that the FBI has no jurisdiction where we live... My dad bought the latest James Bond Bluray. Spent half an...

I don't think that the Adobe subscription is "phone home before every application launch", but here is my arguments against that model anyways: 1. I might go on a skiing trip, a boat trip, travel...

It may well not be right to use governmental force in this case. As you say, disputes between supplier and customer should normally be off-limits for the state. I do believe that an (occasionally)...

DxOMark has an extensive database of cameras. It ought to be simple to extract sensor size and list price from their data, but alas I did not find this option on their website. Of course, this...

Viewed from the outside, it seems that the move from a few large mainstream papers/news channels to a plethora of media sources, some of which are bound to confirm your preconcieved opinion (rather...

I have seen the camera color profile team described as "one guy working out of Boston". The low-level support for proprietary raw files seems to be the work of (open-source) Dave Coffin? My...

Is that for a constant f-stop or constant DOF? -h

What are you saying about LR here? What are your sources? According to the interview of the front-page, it seems that LR will be available as stand-alone for now (LR5?), but that certain features...

Would not a larger FWC mean that, even at fixed read noise levels, the distance between maximum (undistorted) signal and noise-floor would be larger, thus allowing for larger DR (when...
