a call for macro photographers
« on: Fri, 22 February 2013, 22:08:16 »
i have a small macro rig, but rarely have the time to set it up, or grab the kinds of shots we need for the wiki. i know there have been numerous camera threads in other geeky stuff, so there must be other photo nuts lurking around here somewhere ;). if you have a camera that will do relatively distortion-free 1:1 and lighting to match (it doesn't have to be lens-mounted -- stationary lighting setups work fine, as long as you understand white balance, lighting uniformity, etc.), say it loud and proud! we need to set you up with a wiki account :D

I haven't done a ton of macro, nor do I have a ton of keyboard related things to take pics of, but I can try!

Any suggestions on what equipment is needed/recommended?

Clearly an iPhone isn't going to cut it, but I've been considering purchasing a new camera and setting up a proper environment in which to take photographs of my gear. If anyone has any suggestions, I'm all ears!  :cool:

all you need is a camera that is capable of doing low-distortion (or easily correctable) 1:1. some p&s compacts can do this, every dslr and mirrorless cable is basically capable at this point with a true, fixed-focal length macro lens. for our purposes, you want something between 60mm and 135mm (35mm equivalent focal length) as well as a sturdy tripod. lighting and stability are really the trick. if you don't have enough light, you'll need longer shutters; our subjects don't move, so this is generally ok, but you need to keep the camera very still during that long exposure, so you need a sturdier tripod. if you get a dedicated macro flat (see: nikon r1c1 or equivalent), you can get away with less tripod.

personally, i go with fixed lighting (some desk lamps with big _matching_ ccfls in them) and a cheap sturdy (read: HEAVY) amvona (ie, knockoff) tripod off of ebay/amazon. the camera doesn't matter so much, because everything is stable. a p&s will perform about as well as a huge sensor dslr, as long as you have a good lens on it.

take pictures of stuff! super basic things i can think of that we lost as photos of actual switches and their constituent parts, stabilizers, keycaps, keyboard externals, internals, etc.

actually one simple thing that you don't even need to be a photographer to do is run through the photos in geekhack media of sets produced in group buys, different keyboards, etc., and link to them or attach them to associated pages in the wiki

Yespleaseandstuff.

I'm trying to get some photos of Model M controllers and internals for that part of the Wiki. I can get half decent macro of simple stuff, but my camera has issues with anything even slightly visually complex, and fails completely at anything reflective, even properly lighted.

Couple things I could especially use would be shots of M5-1 trackball area and internals, M5-2 trackball area and internals, M13 and TrackPoint II trackpoint mount area. These are all things I've tried to get shots of, with less than no luck. (Unless we can count 'black blur' as photo.)
"I remain convinced I am the only person alive who has successfully worn out an IBM Model M mechanically."

Ok, I'll get to picture taking. Will make new wiki pages as they are needed. I'm not great with wikis so might need some assistance with that part.

oh please. they're keycaps. they don't move, and they don't need r1c1 style lighting or a 105 af-s. a 30 year old 105/2.8 or 55/2.8 micro or at worst one of the af-d 105 or 60mm micros with fixed lighting and macro rail made out of a shop vice and some jb weld will do fine.

the RRS ballhead is just stupid. a 3-way pan head will also do fine.

note that he doesn't even understand that the whole point of the 105 + r1c1 combo is for handheld macro and more importantly, macro shots of stuff that moves (bugs, medical). a friend of mine uses it for dental photography, for example.

also, a carbon fiber tripod for fixed studio macro photography? really? really?

ok sorry rant over.

this reminds me. i want to run a gb for gray cards and white-plates (basically spectrally neutral plastic bits) that are decently sized at actual manufacturing cost from SP. it's quite easy for them to do, but i just haven't gotten around to it. that stupid whibal costs like THIRTY DOLLARS and is just a white color chip with some silkscreening. i mean seriously?

I have a fairly decent, albeit low end DSLR setup. But like ComradeSniper I have next to no mechanical keyboard related stuff and probably won't do for a few months as money is a bit of an issue. I do have a cheap Cherry Brown keyboard right now though, with an IBM Model M arriving that should be here next week.

As far as camera gear goes, I have a fairly heavy tripod and a 1:2 macro lens(Nikon 55mm f2.8 Micro), I have extension tubes so I should be able to get 1:1 out of it, but at a mere 55mm on a crop sensor lighting the subject with any lights will be a nightmare so it'd have to be lit with a long exposure. There is a cheap Nikon 105mm f4 Micro on ebay right now that's going for incredibly cheap, I've been eyeing it up for a while and will try to snag it if I can, but again it's 1:2 without the use of extension tubes. Outbid at the last second, typical!

Are there any particular shots I can get out of the Model M when it arrives? Or perhaps, out of my current Cherry Brown keyboard without desoldering any switches?

EDIT: So it turns out the good guys over at Deskthority are doing a switch tryout, I've applied and if I get the switches I'll get some macro images of each and release those images under a creative commons (or similar) license, for wiki documentation and science!

Things something like this what you're looking for?  Obviously the lighting is pants - I've got an el'cheepo led macro ring somewhere and a plethora of fluorescent lamps - including a ring lamp which I can take the magnifying lens out of... now there's a thought! I just didn't have any of them within a five mile radius and felt like snapping then and there.  It's an old manual 3.5f=50mm minolta macro lens with it's 1:1 tube, I'm not flush enough for a ff camera so consider it pre-cropped :p

yah, but with more DOF. open up that aperture. you can also focus stack if you can't get enough dof. composite multiple shots with the focus set at regular intervals. also, that red shift-like ghosting; is that chromatic aberration or some movement somewhere?

I always focus stack my macro shots, getting good depth of field from a single image is really difficult.

It's a combination of movement and reflection - that orange and blue farnell box is still sitting on my desk and a hand held shot using Canons' built in flash in a dark room.  I still haven't gotten around to setting up for cataloguing my jewellery, and more and more pieces are going out - just never enough time.

serious. flatbeds are great for 1:1

actually, can you flatbed some cherry switches internals? curious to see if they're better than our macro setups can accomplish (the biggest problem with flatbeds is of course their lack of depth of field)

the upside is that they have ZERO chromatic aberration and distortion generally. back in the day they used to call flatbed scanners "copier stands" and they were actual fixed focus cameras sitting at well defined heights above surface plates.

I have a full-frame camera, a macro lens, a few flashes, etc.  I'm not really sure what types of images you are looking for to use in the wiki, but taking 1:1's with plenty of DOF is pretty easy with the equipment I have.  The only thing I'm lacking is a proper macro-rail for focus stacking.

^^^ That's scary :eek:
"Because keyboards are accessories to PC makers, they focus on minimizing the manufacturing costs. But that’s incorrect. It’s in HHKB’s slogan, but when America’s cowboys were in the middle of a trip and their horse died, they would leave the horse there. But even if they were in the middle of a desert, they would take their saddle with them. The horse was a consumable good, but the saddle was an interface that their bodies had gotten used to. In the same vein, PCs are consumable goods, while keyboards are important interfaces." - Eiiti Wada

Probably the most interesting thing I noticed would be the stock lube used by Cherry on certain portions of the metal components in the lower switch housing (I only saw it on at the parts that make contact with the slider).  To illustrate:





Has Cherry always been lubing the slider/metal meeting points in their lower switch housings?

we have suspected that there is factory lube on exactly those points of the leaf switch, but never had a picture that makes it so obvious

So, this is pretty much as detailed a shot of the stock slider lube I can produce with the equipment I have (the only SLR lens I can think of that would produce more detail is a Canon MP-E 65mm f/2.8 1-5x):



So, who wants to guess what lube they use?

taste and smell is typically the differentiator here ;)

It's scary to think that that blob of grease is probably less than 1mm across.

Excellent photos!
"Because keyboards are accessories to PC makers, they focus on minimizing the manufacturing costs. But that’s incorrect. It’s in HHKB’s slogan, but when America’s cowboys were in the middle of a trip and their horse died, they would leave the horse there. But even if they were in the middle of a desert, they would take their saddle with them. The horse was a consumable good, but the saddle was an interface that their bodies had gotten used to. In the same vein, PCs are consumable goods, while keyboards are important interfaces." - Eiiti Wada

i was serious about taste and smell by the way. traditional greases will smell and taste like good ole mineral oil. lithium and ptfe greases typically have very little smell, and either a metallic taste or be pretty tasteless. more importantly, if it's a lith or ptfe, it will have either very low viscosity or very high.

very curious to know what they're putting on that crosspoint now, as grease formulations have changed a ton since cherry first made switches, and we've shown anecdotally that the grease formulation makes a huge difference in the switch feel.
