The next time it is apart do the old AVO trick of making a sticky area inside for any floating fluff to stick to. AVO used some gloopy grease painted inside the rear case.

Don't dismantle your camera to treat this, do it in software!

Any decent image-post-processing software can be used to identify and tag pixels that are recurrently and failingly 'compromised' then offer you a range of options as to how to handle the blobs so they blend into the rest of the image in a non-intrusive way.

It appears to be a 'known' problem with some extending lens cameras: the action of the powered extension and telescoping of the lens draws in detritus. Using software is and remains an option but stringy fluff and small particles have a habit of moving about the sensor, besides with any small sensor the area obscured can be relatively large.

I may well try the 'Avo trick' if I can find somewhere to smear a dab of grease.

That said, for such a compact size, the camera is a very good performer with a long zoom range.

I have downloaded 'darktable'. I've not had time to take a really in-depth look at it but it definitely looks like a promising alternative to Photoshop. As I'm running Windows, there may be a few glitches along the way as it is early days for the darktable windows version. We shall see. Thanks for the heads up on this promising program.

I chose Panasonic because they where not camera makers, I imagined that the design remit was "to take pictures" it does that admirably. I have had a bit of a paradigm shift from camera user to picture taker, rather refreshing. It has couple of very nice details, the mode dial has a much stronger detent than the others, reducing the possibility of changing it by mistake and the flash has to be popped up by hand, invaluable in museum photography.

My Lumix that I mentioned earlier is an FS16. I agree it's a great little camera, and I haven't noticed a lens fluff problem, but maybe I've just been lucky. If anyone comes across one of the DMC-FS series in their local charity shop for a tenner or so I suggest that they grab it. Third party chargers and batteries are available for little money.

They do it to stop you going elsewhere when you feel it's time for a new camera, and also to ensure any pirate copies of the software are less useful to anyone else. Then they change the data formats to be incompatible with older versions of the software, creating a form of planned obsolescence. It's a common trick in the world of proprietary software!

I understand later versions of Lightroom (and very likely other image packages) will render the proprietary files satisfactorily, but of course this is a trick to get you to upgrade the software that will allow you to use cameras from different manufacturers!

I get the impression that to counter built-in obsolescence amongst camera manufacturers, they will offer software upgrades as time goes on. It seems like the whole process of digital photography from the camera to the PC and all the software on the journey to an image is deliberately hobbled to make money. Even if you get hold of an older, perfectly worthy digital camera, the software drivers to run the image processing will not necessarily be reverse compatible. It's forever onward, whether ready or not.

On the subject of 'darktable', can anyone enlighten me as how or if- it is possible to resize an image? Admittedly I've done very little with the program so far but I did need to resize an image and couldn't find a way to do so.

Paul, here's a link that might be of interest:

Just a comment on Photoshop alternatives. The very inexpensive "Affinity Photo" from Serif matches Photoshop in most features and exceeds it in some.
https://affinity.serif.com/en-gb/photo/desktop/

Going through the official tutorials demonstrates some of the power of this excellent program. https://forum.affinity.serif.com/ind...tutorials-200/

(Windows or Mac, no Linux version.)
