Enjoy Very Long Exposures With Will Cheung And MPB

Keep it clean


Time for an update: I still use film, though. Not vast quantities, but I have a darkroom, and I'm not afraid to use it.

I enjoy every image I take: I hope you'll enjoy looking at them.

Keep it clean

27 Dec 2021 10:31AM   Views : 482 Unique : 267


Anyone who has consistently read this blog will know that I don’t actually keep my photographic gear meticulously clean – you’ve seen the dust in the knocks and crannies and watermarks on the front elements of lenses. So you may be surprised to know that I recently cleaned a couple of batteries really well.

The truth is that I put a pair of trousers in the washing machine oblivious of the fact that there were two camera batteries in the back pockets. One of them emerged slightly discharged but definitely working, the other one – as you can see – fared slightly less well.


So I think I may have a new year’s resolution to take more care about checking my pockets before putting clothes in the wash. The good news is that I haven’t done anything on the ‘do not’ list on the side of the batteries: the washing machine ran at 40ᵒ Celsius.

You develop your own films don’t you?

If you have your own darkroom, or if you use film cameras regularly, there are always a few people who mention the attic. As in ‘Grandpa’s cameras are in the attic. I don’t even know if they have film in them!’ This leads me to ask if I can have a l...

Do you have any experience of cleaning the lens where inside the front glass there is apparent fungus...

I have seen a few useful links on the youtube how to clean the inner part of the lens (100-400 IS canon)...I am not getting that confidence to do it by myself...

I fairly often leave things in pockets, so much so that Mrs M8 checks every pocket of mine before putting the garment in the washing machine

That's a really good question, Somnath.

And the answer is no - but I will do some research. My memory is that the advice is generally that there's nothing that can be done, certainly not without taking the lens apart, making it a professional job. The same advice suggests that fungus spreads from one lens to others: and that the best way to avoid this is to keep everything dry and cold - which isn't easy in a hot climate.

If you can get to the surface easily, I'm guessing that alcohol will probably kill and remove fungus, although there may be damage to the surface of the glass. The big problem, I suspect, is getting the distance between elements right on reassembly - which is, I think, called 'collimation' and can seriously affect sharpness.

With a lens that's badly affected, there's not much to lose, but if you can't tell the difference between results with the lens before and after fungus has appeared, leaving well alone may be best.

There'll be a future blog...

I heard of cleaning up your act John but this is taking it a little too far...

I have to admit that I often carry a spare battery in the coin pocket in jeans and something you could forget to take out. I have not done it yet but there is still time.
Have you notice how that pocket is just the right size.

No, but when keeping your lenses horizontal in a furniture with a glass door that allows sunlight to come through them the chances of developing fungus are less.
