comment Do Left and Right matter in how the photo is perceived?
I on occasion flip my images left for right to see what difference makes. To me the perceived difference can be substantial, and sometimes surprisingly so, but there is no guarantee that others perceive the same difference.

comment Do Left and Right matter in how the photo is perceived?
Does this mean that photos targeted at top to bottom script users should have people lying face down if peaceful and face up to indicate tension. And the opposite for BTT text users? [·] <- non printing smiley character.

comment Is it necessary to fully drain Ni-MH batteries before recharging them?
@Lu'u Vinh Phuc - the quoted Wikipedia reference is 'rather old' [2002] but there are some modern sources which discuss related effects. See my updated answer.

comment Night photo with Leica 25mm: blur at f/1.4
(1) Shine light on subject at left. Use spot centre focus or an off centre focus point to focus. Recompose photo while maintaining focus setting. Light off. Go. or (2) Set focus manually to match target (usually very hard at f/1.x)

comment What kind of lighting do I need for a halo portrait?
One aspect only: If you are trying to do this 'in the field' with minimal equipment then fill flash will help to independently control face brightness. Relative flash to ambient exposure can often be selected but range may not be enough. Flash set to manual allows more range. You can add a diffuser to flash if necessary to get even less light.

comment What Will Make Me Buy the D800 over DF if the former is cheaper?
DF/D800: No video/video.| DF has best low light performance of any 35mm camera ever sold. Unlike the D600/D800 the actual sensor noise per pixel is lower than for a D700. BUT many other factors too.

comment How can I get the top people of a camera brand to listen to a design idea I have?
@ClaraOnager - I'll admit to being quietly amazed at your comment about the sheer level of comments "showing the badness". Did you READ the comments? Yes, there are numerous negative ones - (one person went to every answer and made comment to help keep the -ve count up :-) ) , but there also many useful ones which have helped me substantially and which will help some other people too. I think all the answers are useful and there are 40+ upvotes on them as I write this. Apparently your expectations of a 10k user (or 13k6 fwiw :-) ) is not quite the same as everyone else's.

comment How can I get the top people of a camera brand to listen to a design idea I have?
Update: Pretty sad really. I see the downvotes slowly growing. And this has been a very worthwhile exercise for me. And ultimately will quite likely be useful for others. But it is slowly going +3/-4, +3/-5 ... and soon enough it will die. Which is sad as WHILE the various comments have been valuable and useful and largely enough correct AND have added some guidance, they have not reflected reality as I have managed to experience it. I think :-). Hearing the whole story when it can be told better is likely to be of use to others, but, by then it will probably be gone. A loss to others.

I seem to have obtained the access I desired - now I just need to present it succinctly and cogently and we'll see how it goes. I'm in the midst of writing it up 'formally' but had an occasion to outline it informally "off the cuff" in private to a friend and saw how badly I can manage to summarise it without much effort. So, care required, but ...

I do 'like' the way jwenting has gone around many of the answers dropping in the same negative comment in slightly altered form. More into will be provided when it's 'safe' to do so.

... ignoring the many peripheral ones. I "invented" the Sony SLT on paper in 2003 after buying a superb Minolta 7Hi and realising where SLRs would go. It took Sony a few more years to buy Minolta and follow me :-). I watch camera interfaces and note how people are thrashing around to and from without making quantum leaps in control methodology. The time has come :-). The way the world works is the best I will achieve is to point to this thread and say that I almost managed to be 1st. No prize for2nd.

@jwenting - Twice? Dozens of times :-). The drier was obvious but useful. I didn't have internet search then. I Ps the rocket pump so did not seek to gain from it. That my "wheel" was essentially in tie sync with Macdonnell Douglas leaves a fairly good feeling. I saw (really stupid) a loophole in their patent that would allow me to bypass it totally - not of interest. | BUT I started with a Box Brownie 50 years ago :-). I bought an SRT303B thereby more or less welding myself decades later to Sony (due to A mount lenses - as happens). I've had about 9 digital cameras in a row ....
