I grew tired and deleted my Instagram account couple of years ago but created a new one some time later. I just haven't been very active user since. Anyhow I'm now building a 8x10 camera and chose to...
Good point. I'd buy an old camera if I just wanted to shoot with it but for me building stuff is part of the hobby too :)

Thanks a lot for the suggestions! I'll look in to them.
I'm planning on building a 30x40cm (12x16") camera. The camera will have bellows and some sort of geared fine focusing.
I'm testing with simple meniscus, magnifying glass, etc. lenses, but I'd...
These are polypropylene tubes. PP can be welded but I used just a soldering iron to cap the ends with a piece of PP sheet. Ugly but works. The tubes are cut from central vacuum cleaner pipes. This is...
I'll let you guys know if I ever get back to this. So far I've been happy with the tubes as is.
Thanks, Toyo.
Thanks Nicholas! That was pretty much my thinking when I took the pic. I took a few pics closer to the hut too, but unfortunately there were no people around at the time, so they are of less interest.
One from last July. A goahti. This one is a permanent old style sami hut. Made of plywood.
Some 40km as the crow flies from the neareast road. About 60km on foot. Enontekiö, Lapland, Finland.

Kudos to the moderators! I'm not a frequent poster but I read this forum quite often and I was a bit worried where this all is going.
Thanks! That was taken at the evening, can't recall the exact time. The sun is pretty low allthough it never sets that time of the year at that latitude.
One of the 6x12 frames from my hike in July 2015.
A view to mount (fell) Tierbmesvarri, Enontekiö, Finland.

Couple of iphone/instagram shots from my hike last July. Enontekiö, Lapland, Finland.
So what happened with this one...
I did finish it. I tried it a few times and it worked pretty good. The fact that I hate those Jobo reels lead me to other direction though. I made me some...
I was in the same boat as you. I was tempted to buy the Chinese one and even read some favoring posts about it. However I ended up buying a Harrison and don't regret doing so. Very nicely done and...
To me a framing tool (director's viewfinder in my case) is an essential tool in landscape photography. Especially when hiking with large format gear. I consider the viewfinder as my 'camera'. The 4x5...
I'm modifying mine. I'll post a pic or two once done. One of the learnings have been that what I liked for 210mm/F5.6 and 300mm/F9 lenses apparently is not dark enough for a 90mm/F8 lens. So I need...
I bought one a while ago. Actually read your blog post before I did :)
I have only put a few rolls through it but it really feels like a solid piece of kit. Comparable in every aspect to the...
I have a drill press, a lathe and a mill with a rotary table but i prefer to use a jewellers saw for cutting the lens board holes. Less time, less hassle but more than decent result. I just mark the...
I was goin to sleep but instead decided to try this out quickly. Shot a 4x5 negative from MacBook Pro Retina display. As the screen and the negative have different aspect ratio I tried to frame the...
Sorry to wake up an age old thread but as I was searching for some info on soft focus lenses I stumbled upon this picture. What a marvellous portrait, wow!
I just made a darkcloth for myself the other day. I previously had a thick cotton cloth that is lightproof. But it's airproof too. Almost kills me every time go under it. Be it indoors or outdoors....
Thanks again. Yes, it would be hard not to keep it within +/- 0.005" :)
I'm tempted to make the lens and I have all the material needed for the barrel. Only thing I don't have is time...
Thank you, I get it now.
By the way, what is the acceptable tolerance for the airgaps?
I was thinking that the aperture on the D25S is probably offset but that is not indicated in the drawing...
This is interesting. I would like to try to do something like this at some point. May be not in the near future though. Anyway I drew the attached diagram to check if I'm following your description...
The machine runs on DC (24V) and I believe it came with an international power adapter. If the adapter says 100-240V 50-60Hz it should be good to be used anywhere in the world. You just need the...
Haven't had much time for this but yesterday evening I managed to etch a pcb for the control panel. After taking it out from the soup I realised there is at least one mistake in the schematic... But...
Thanks. I'm using Arduino because I find testing with software is lot less pain than than swapping caps and resistors and what not. Arduino is great for prototyping and so is a stepper.
That...
Thanks Drew. The eccentric roller is something I will look into. The good thing about stepper/micro controller setup is that it would be possible to program presets e.g. agitation patterns etc. for...
Thanks. I'm not sure about the spec of that motor. It's an older type and I cannot find a data sheet for it. It is an Unipolar motor and I figured out the wiring by measuring coil resistances....
I have thought that too. I'm going to experiment with that if I get uneven results.
Good point. I expect that everyhing is slightly out of tolerance so the feature will be there naturally :)
No problem sharing. Other than the fact that I do all the thinking by prototyping so there are no diagrams :) But I'll try to document this a bit in the end. I have different kinds of stepper drivers...
Thanks, that would definitely be a good idea.
Thanks Dirk, that was my initial thought too and I will do that if I decide to make an other version (I still have four roller skate wheels...
Spent some time today breadboarding the user interface. Tried to keep it as simple as I can.
The UI consists of a LCD display, two push buttons and a rotary switch.
The LCD shows the chosen...
Thanks Everybody!
Yes, thanks that retainer idea is probably a better idea. The tank I have is a Multitank 5 two reel tank. It is slightly conical but that is compensated by positioning the...
Thanks a lot Ari, polyglot and muihlinn and Kirk!
I now have good starting point to try out and actually develop a sheet!
I was thinking about magnets and it would probably be the best...
Hi,
I got myself a Jobo 2500 tank and a 2509n reel couple of years ago and tried to use it in upright position like I would use a smaller tank with 120 film. That was rather cumbersome with the...
Oriental cameras have a lot in common with your camera.
For example this one: http://kanscamera.sakura.ne.jp/hp7/html/p108.html
I have a plethora of lenses in various formats but know next to nothing about the thinking behind them. So I really appreciate your time and willingness to share this stuff. Valuable reading. Thank...
