Last time I checked the United States was still not a signatory of the Ottawa Treaty - so there is the solution. Of course, the smell of the putrefying remnants of humanity's dregs may detract from...

Lucis is unique because the differential hysteresis algorithm, on which it is based, is patented. I believe it was originally devised for enhancing medical imagery, but has found favour with ...

Cheap enough to experiment with I have a couple of these. One has its camera head removed waiting on a custom cable to remote it. The second has the window removed with the lens off so I can swap ...

to the two commentators above. Island hopping trip already booked and adding Durrell's book to my Kindle.

Planning a trip soon, but for medical reasons limited to wide angle and standard lenses. Anywhere on Skiathos worth a special trip? Recommended day of week/time of day? Anything I need to know ...

Anyone want to buy some mini IR cut filters?

Placed 24^th in the challenge. Repeating rectangular warp of a close-up of a cat's face.

Interesting location. Black and white was a good choice to emphasis the bleakness. What I don't like: the composition could have been better. Look at the lines of the trees/lamps. Something could...

Not allowed to take them away (anyone who has been to an NPS preview will know the drill). Pixel peeping on the back the most impressive thing (and the same for the D5) was the performance at ...

Hmmm, these are two very, very different beasts. The D500 is a fabulous camera - I have handled a pre-prod SAMPLE, had the NPS spiel and even I want one; officially I had turned my back on DX. I ...

Three things against upgrading: 1. Size - the new lens is bigger - to the extent it would not fit in one of my regular bags when attached to a D800. 2. Optical quality - by most accounts it is ...

A is very similar to C in terms of distortion - so does this indicate similar design. I prefer B although I am hard pushed to say why - is this the most modern lens? I care not for investigating ...

Placed 2^nd in the challenge. Custom Python coded multi-scale CLAHE run on monochrome image formed from original blue channel. Image run through twice!! Then loaded into PS for median filter (to suppress JPEG artefacts) followed by USM (100,1.5,0) to bring out crater edges.

Just when we thought digital had kicked film to death we discover the modern bain of interchangeable lens photography. Back in the days of film the film carried the dust with it - there was the ...

Interesting quandry. I have a D800 converted to "full spectrum" on the company account. This effectively makes it a D800E as the OLPF has gone to be replaced by a quartz window. It functions fine ...

If the bad grammar of the alledged 'statement' was not sufficient warning then I know a Nigerian prince who wishes to share his fortune with you.

So Phase One Industrial, who make some mighty fine digital "medium format" aerial cameras, are finally going to get some real competition. If things like 80 Mpxls, fast leaf shutters and forward...

@HowaboutRAW
nerd2 may not have handled it - he/she just might have studied physics in school.

You've not seen the 'blad 'compacts' then? ;-)

Could not agree more. Furthermore, Mirror-less require a new lens series (re-investment), or less than perfect adaption, but the power issues are stlll overlooked. In a DSLR the photons in the...
