On Wednesday I received these filters for my 3m respirator from a very nice chap in the IOW (@Wightsparks ).

Put along with the filters I already have & I've enough to last a few years!

I've also bought a spare mask on ebay so I can leave one set up for dust & the other for spraying.

That looks like one of the pics the Police would release after a successful drugs haul

Do you store your meter next to your keyboard? It looks to be in a similar condition.

Funny you should mention that.

Every breath you take, i'll be watching you.

No, wait, wrong police.

Have you been beside these "filters" and breathing in and now you are walking on the moon ?

For less than scrap price!
Getting it on and off on my own was errrm risky as it weights i recon nest part of a ton

Been after these for ages. These are American made and quite difficult to get over here, don’t know why?

They are police approved scale rulers for forensic photography

so calibrated, presumably?
what purpose do the circles serve? compensation for parallax error?

No not calibrated, not designed to be. These are just to illustrate size and scale. Only work if the photo is taken 90 degrees to the viewing plane.

Anything that needs to be measured has to be done with calibrated technical equipment.

The circle should appear as a circle in the pic. If photo is taken from an angle the circle will appear as an eclipse, therefore the ruler cannot be used

As they say in football commentaries "The boy done good".

The three circles are to ensure the picture being taken is square with the scale

The three circles of equal diameter that are used to help ensure perpendicularity of the camera with respect to the orientation of the ruler’s virtual plane.

thats what i meant by "parallax error".
probably have the wrong word.

Lol, that’s why I said90 degrees to viewing plane as I didn’t understand parallax error.

It’s a big technical word, it’s friday and I’m tired from the week

But I think we are both talking about the same thing

I got a new truck!
