I have 25 years of programming experience, going back to the Apple ][ days and Vic-20s and so on. Wrote my first commercial app (something I got paid for) in 1982, and I wrote a locally-successful game for the C-64 in 1985. I work in telecom, and have a company of my own. My hobbies currently are programming, RC model aircraft (planes and helicopters), rifle and pistol marksmanship, and photography.

comment Why is there an ISO setting when shooting raw?
Minor note: increasing the ISO does not increase the number of photons hitting the sensor. It increases the strength of the resulting signal from those photons. Only the lense aperture and shutter speed can change the amount of light you're getting - but you can be more sensitive to that light.

comment What do I need to make my own camera stand with a 40" horizontal arm?
What she is using looks wicked expensive. I have seen stands like that used for machinery in manufacturing. It looks custom made though. Machinists are always looking for jobs to do. If you can find a machine shop in your area, someone can build something like that for you, but be warned, it's gonna cost thousands of dollars. They usually won't design it for you either. Why don't you contact the person in the video and simply ask where they got that thing?

comment Is 85-135mm really the best for every single kind of face?
And that would be a subjective opinion and we don't give those here. All I can say objectively is the effect will be the same for anyone. It is up to the viewer and the artist if it looks good or not.

comment How to place my camera on uneven surface to take time-lapse photos
Warning: Be sure to get the right one! Popular versions which you find in stores are not strong enough to hold up a standard DSLR.

comment Does my lens “mm” define the zoom
And, at F4.5 you won't be taking photos of the moon without a tripod anyway unless you bump up the iso, which causes noise. But YES - longer focal length = more "mm" in the description = bigger enlargement = more zoom (vernacular). I think you need to improve your question to more of "what equipment do I need to shoot the moon" with my camera. Be sure to include exact descriptions with exact model names, especially the camera body.

I called the newspaper yesterday and they are looking for it. That photo was run in a small town weekly newspaper, back in 1985 or so and there's no electronic copies going back that far. They are friends of the family so if they can find it, I'll get a copy.

comment Do I need a filter to use my Canon EOS 60Da for daylight photography?
Ah, what a difference one character makes. I'll stand by the general tone of my comment though. I'll edit the question with the 60D*a* in mind.

comment How does one best deal with shaded faces in bright sunlight?
I do this a lot at model airplane events... I just tell them to turn around. Usually having the group face a different way is more possible than it seems at first. USE the sun, don't fight it!

comment Wise to switch from Sony to Canon considering I have a decent amount of lenses?
I think you're making a mistake by saying that the system is obsolete if the mount isn't supported any more. Sure, they won't be making new lenses for it, but what do you care? You already have good lenses, everything you need. You can use that camera for the next twenty years till it stops working, so why not do that? There is no clear advantage to switching and buying all your stuff again. You already have a good camera - a Canon won't be better simply because you can get lenses for it - you don't need lenses, right?

comment Timelapse for sticky notes
If the image is only changing when a new note is put up, you only need one shot after each note is put up. If you want to capture people moving in and interacting with the wall, then you'll want a shot every certain interval. One "expensive" way I've done this in the past is to just video the entire event and then edit the video to playback at whatever speed I needed to get the exact run time I wanted. Most video cameras today can easily fit 8 hours or more video on one card - you can reduce the quality if you know you're just going to speed it up. Uses GIGs of space, but simple to do.
