So I was in need of a light tight bag for a film test and realised (thankfully before taking my film out the can) I didn't have one!

So in true Blue Peter style (UK residents will know the reference) I made my own with a bin liner, some sticky back gaffer tape and some Velcro!!

Doubled the bag, taped each end up and the covered the entire bag with black gaffer tape. Made a lip at the top with gaffer and stuck some Velcro on it.. Hey presto, a light tight bag for temp storage of exposed and undeveloped film

Just thought I'd share my day!

 
You must have much better/thicker bags than I can get as I have not found them to be lightproof.

I used to think they were until I noticed the practice of some of the companies digging up the roads here. If they needed to cover up road signs, they would do it with a black bin bag. All is fine during daylight hours but when the workers leave and it gets dark, some of the signs are illuminated. In this caes, the black bags might as well not be there!

I think the layer of gaffer tape does the trick!
 
(Steve, drive carefully! I know this bagged traffic lights too. Seem to have been switched off anyway over here in these cases.)

Even if such bags are lightproof with visual light, they might not be so for infrared light. Another issue when dealing with IR-films.

Here it would be "MacGyver". Nicely done.
 
Well I just used it and it works a treat! Hurrah

Will check out McGuyver and Red and Green!!
 
Hmm. I got something made similarly, of black cloth. Bag within a bag. Haven't light tested it yet.
Test it similar to bellows?

I've got a big roll of black polypropylene I got for covering my vegetable garden in the winter. I can't remember off the top of my head how thick, maybe 6 mils? Anyway I've made envelopes for keeping exposed and unexposed paper negatives from it, doubled. They've been out in a summer's worth of full sun without any fogging. Downside is that the static buildup in the plastic attracts dust and dog hair....
 
A biskuit box and a strip of electrical tape would do in most cases too...

And one finally would have reason to eat those biskuits. In this context I'm not sure about those black bags.

Nice work. Could somebody from the UK please explain the "Blue Peter" reference?

Iconic childrens TV programme, famous for making things out of cardboard boxes, yoghurt pots and sticky backed plastic///

Thanks, Steve. It's one of those slightly annoying sayings. We Australians probably have more annoying local sayings than most.

Neat! I'd go with extra black trash bags though, found out when doing a temporary room sized camera obscura, for my class, even the thick industrial bags from the janitors needed at least 3 layers.

Actual changing bags have an internal bag that's coated with some rubber material.
