'Tango Dancers' film for Mr. Plastimime

Here's the fifth webisode of the Behind The Scenes series I've been shooting/editing at TANDEM in support of Daniel Greaves' Mr. Plastimime project.

More Adventures in CAD

For the last few weeks, I've been getting to grips with a trial version of Geomagic Design (formerly known as Alibre).

This is a CAD package that goes a lot further than the free Autodesk 123D Design I've been using previously. The main advantage seems to be the parametric structure to the programme which allows each part to have a complete history of non-destructive changes. Parts are initially designed separately, then brought  together to create an assembly. There are lots of alignment and constraint tools available to do this to a high degree of accuracy.
 
My plan is to at least learn at least enough CAD to be able to draft my projects and have them 3D printed from time to time. Here we see a plan for a very simple (and probably somewhat naive) device to help me digitize 8mm movie film. I've been messing about with something like this made of card and foamboard, so getting it made in plastic ought to be something of an improvement.

So it's a stepper motor with a sprocket wheel attached and a film channel to guide the film through. Maybe not rocket science, but it's a mechanism and will need to be made with some precision if it's to work in any way at all. One day I'd like to 3D print this at home, but in the meantime, it's off to Shapeways.com with my .stl files again...

Serving Fine Web Pages For 17 Years

Big thanks to old friend (and painter of visions) Nicholas StHelier. He's dug out an old postcard I made back in 1996. It's a calling card I used to give out to people to invite them to come and see my website.

Those were very different times...

The Tall Story Hotel was hosted on the free webspace I got with my dial up internet account from Pipex. Thus the snappy URL you see here. Looking up my record on whois.com it looks like I didn't register the chrisgavin.com and chrisgavin.co.uk domains until a few years later (May 5th 1999.)

Of course the link on the postcard is long dead now, but the page you are reading this on now is the descendant of that first site. The code, graphics and hosting service have been changed many times since of course. The current version of www.chrisgavin.com isn't really a proper website at all in the old sense; since August 2005, this has just become a sprawling collection of Blogger pages.

It was quite exotic to have your own website back in 1996. I must have been quite an early adopter. A year or two later I bought one of these too. Quite the dotcom boomer!

Back of the postcard, yep there it is ... 1996 !!!

My Most Exciting 5 Feet Of Film Ever

What could be more thrilling than seeing the daredevil stunt riders of the Ken Fox Wall of Death in action this weekend?

Well, supposing I captured some of the action with my Nizo super 8 camera using some black and white negative film. Then suppose that a mere 2 days later I wait 'til it's dark, sneak into my loft and put about 5 feet of the film loosely into one of my dad's old Paterson developing tanks. Then, maybe I head down to the kitchen and mix up 500ml of Caffenol C-M film developer (instant coffee, washing soda, vitamin C & water), process the film (15 minutes), water stop bath (5 washes), Hypofix (10 minutes), wash (10 minutes) then fast dry the film with a hair dryer.

Then just supposing there were actually some pictures on the film strip... How exciting would that be?

Well tonight, that's exactly what happened...

This is the first time in a very long time that I've processed any film of any kind. It's certainly the first time I've processed any cine film, and most definitely the first time I've processed film using a coffee-based film developer. (Co-op Fair Trade Instant if you're asking).

This first test film was just jumbled up willy-nilly inside the Paterson tank, but it certainly proves the chemistry works. Of course it would be better to use a proper cine processing tank, especially for developing a whole 50 foot (15 metre) cartridge in one session.

Once I had my 5 feet of  hand processed film, I then put it on my light box and took a few close-up stills with my DSLR camera and some macro rings. This is hardly the best way to get a telecine done, but at least this way, I can show some of the results.

It's very late now, but of course I couldn't resist putting a very short movie together out of these first few frames ...



I just couldn't be more encouraged by this first test. I hope I can digitize the whole 5 foot strip to show soon and I'm now very keen to process the rest of this reel with this chemistry. So much more to do with this...

Spiral 002

Here's what that 8mm film developing spiral might look like.. .should somebody try to CAD model it in Geomagic Design...

I'm currently trialling this software and making some progress with it... The most basic version of this software is called Geomagic Design (Personal Edition), and I'm thinking this is a pretty good tool for this kind of work, and certainly a whole lot better than the Autodesk 123D Design (free) application I've been using so far.

This model is the lower half of the film spiral only. There will need to be a top plate to keep the film held in place, but that part will be of a much simpler design.

I uploaded this as an .stl file to Shapeways.com, the estimated price to make this part would be about £80. Just at the moment this seems a little bit too much to spend on this project, so I'm hoping to find a service / 3D printer owner who could help me make this for a little less.

This Is Me On French TV!

L'Oeil de Links - FUTURA GOLD

Well, let's say it's a very select group who have discovered my typographic web series The Futura Gold. Fortunately, amongst the people who have found it, were the team who put together L'Oeil de Links; a rather special TV show about web creativity shown in France on the CANAL+ channel.

A couple of weeks ago I got an email from Jeff Tinard the scheduler for the show, asking if they could broadcast my films and record a Skype interview with me. The resulting programme was broadcast yesterday and I'm pleased there's already an online record of the show on the CANAL+ website. The clip above gives an excellent introduction to the history of the Futura typeface, then follows with Episodes 02 and 03 of The Futura Gold complete with an interview with the director. Hmm, is that really me grinning like a madman through all this?

Adobe indulges in 'Creative' Pricing $ to £

I've spent the afternoon trying to work out what the Adobe 'Creative Cloud' software subscription service means for my workplace, and it's really not good.... 

First up, there's this... 

Adobe CreativeCloud for Teams $69.99/user/month (for US customers.) 

Adobe CreativeCloud for Teams £65.44/user/month (for UK customers)

Erm, same software, same cloud storage (which we don't actually need), yet at normal exchange rates that's $100.17/user/month for UK users. A price hike of 153% for us Europeans. For a cloud service how can Adobe possibly justify this market segmentation?

Well on Adobe chat today this was how that bit went...

Adobe spokesperson: We understand your concern. We want to make sure that we are giving our Customers the best products and at the right price. Although Adobe Europe and Adobe US are different parts of the same global company, European Marketing strategies and pricing are not directly related to those used for the US. The prices are not simply converted from the dollar pricing used for US products, therefore the pricing used for each country in the EMEA region may vary.
 
And there's more... oh yes, a lot more ... 

New Spiral

Pretty soon I'd like to try DIY processing some cine film for the first time. Processing stills film is pretty straight forward, but super 8 cine film comes in 50 foot (15 metre) lengths. This is not going to fit inside a Paterson tank and anyway, there just don't seem to be any 8mm film spirals either.

Folks seem to use Russian Lomo spiral tanks to do this, but I can't quite bring myself to send lots of good money away to buy a hunk of soviet-era bakelite from ebay. I'm guessing that many of the available tanks will be broken or have bits missing by now.

So what about designing the vector graphics for a new spiral and having it made from plastic? I would think this could be a job for a laser cutting or 3D printing service.
It might look something like this...

By my calculations this would need to be about 220mm in diameter, the channel for the film is 1mm, as are the ridges between the winds. This is a theoretical design, but who knows if this would work, or if the film could actually be loaded into such a thing? The next step will be to find a cutting/making service that could make this up for me at a reasonable price. Please comment below if you know of such a service.

Sumix 150M industrial camera tests again.

camera Sumix 150M, c-mount Fujinon TV zoom lens f1.8 17.5-105mm

Working late in the lab again tonight trying to see if my old Sumix 150M industrial camera can be used as a webcam (for an interview request), but it doesn't look like it can be. I bought this off ebay years ago; it's a curious little camera module for scientific/industrial uses. The Sumix 150M can shoot stills or video at up to 1280x1024 size; but only in monochrome. The Sumix camera capture software has lots of controls that you just don't get with consumer oriented gear. 

Also, the camera can take C-mount lenses and I was intrigued by the macro possibilities of the camera using some extension tubes. My goal was to try to capture frame by frame 8mm cine images from the gate of my cine projector, now that I look at it again, I wonder if that might be worth another try...

For all it's specifications though, I don't think it'll work with Skype...

Anyway, below are some test captures I made with the camera back in the day. Mostly macro photos using more and more extension tubes until I got down to the required 5mm or so image size of the 8mm film frames. I gave up with the super 8 capture experiments, but I did end up using this strange camera to shoot all of the stop motion elements for my film TXT ISLAND.

The camera is tethered to the PC by USB, so only able to take pictures of things nearby!

With a few extension tubes, macro photography becomes possible.

Some desktop clutter, surprisingly sharp.

And in we go until our image is 5mm wide.

I've been too busy working on something at TANDEM the last few weeks, so there's just not been any time for  DIY film-making activity at home recently.
However, when I get a little spare time I'm going to try some of this in my Super8 camera.

It's 50 feet of black and white negative film. I'm hoping to try out some DIY film processing and figured that this BW negative would be the easiest type of film to start with. Processing is similar to BW neg. stills film, with affordable chemistry at room temperature. I'm also very intrigued with the idea of 'Caffenol C' processing... Yep, that's film developer made from coffee!
