Linen drafting film

[duncan webster 1Participant @duncanwebster1]

The technique for altering linen drawings where I worked was either for small mods erase the original with a fibre glass scratching pen, fill over with snowpake and then draw in ink over that, or for bigger mods print onto plastic film, which we called Ozalids, and then alter that. I've since found that Ozalid is a company name, they supplied all sorts of drawing film. For new drawings, the early layouts we used ' butcher's paper' and normal pencil lead in a clutch pencil, for final drawings special plastic film with special leads, or sometimes ink for stuff intended for advertising. Pencil leads sharpened with a smooth flat file. Your shirt sleeves got mucky, both from sharpening and touching the drawings, some of the older guys used cuffs over their forearms, saved on washing I suppose.

Can someone please explain to me why photography is a a diy solution? I used a full frame dslr with prime and TS lenses and I personally think they are very good.

Digitising them should have been done years ago

Do them in strips, through a scanner

I do wish the owners of these sorts of things wouldn't hide them, hoping they make loadsa money later on

The Model Engineer had a huge collection of stuff when the Luftwaffe came a-calling early in the war

All gone forever in 10 minutes flat

DIY as in it does not need an external service provider or professional equipment.
Even a APS DSLR will be fine for this.

With many 'Photos' of plans, when adjusting contrast and brightness on an electronic manipulating programme, I've found the corners 'drop out', a different brightness, like a fish eye. Gallery type cameras are a different kettle of fish (bad pun).

Hi, I've given my drawing that I've shown earlier a go with my Canon 400D with 18-55mm lens, set at about 31mm. While it took a decent picture, I think a studio level lighting would be a lot better, mine is done with daylight coming in through two windows, which are at right angles to each other, and a certain amount of washout can be seen from the light on the right hand side window.

I think I prefer scanning, as even this quick way of doing it, took longer to set up, but if one is doing a lot of them, I guess one would have a dedicated set-up.

Regards Nick.

The linen drawings, some older than 100 years, are in excellent condition. Two have been copied for someone out there. Photography did not really work but a flat bed scanner produced very good prints.

Thanks to all
