Marks on photo

[realspeed]

in The photo above there is a smudge mark at about 11 0’clock
below mark removed

so how did I do it?
the obvious answer is tgo edit it out, but thatdoesn’t help with the next photo taken.
No the answer is to remove it from the sensor.
This could mean sewnding he camera away and waiting weeks to get it back, or DIY.
I have done this many many times and saved a fortune by not sending the camera away.

So how do I do it?

First of all one needs a camera LOUPE as below

this has internal lighting to help finding any diurt on the sensor

so it isplaced over the camera as one would with a lens but just resting on the opening

now it is easy to see the exact area on the sensor the bit of dirt *smudge" is

the next bit of kit needed is called an Artic butterfly

being battery powered the brush spins at high speed to build up statric electricity
how to use

switch on and let it spin for a couple of second then turn it off
carefully brush over the sensor and any loose dirt goes onto the brush .

then check with Loupe

Sometimes you astound me RS…

You go to all this (commendable) trouble to fix up a photo yet you leave 42 seconds of black screen on a published/uploaded video. The later is something which could be fixed in seconds in a simple free program like VLC and is your preferred hobby. I don’t understand it.

I’ve only ever experienced rubbish on the sensor once, and a puff of air cleared it (with camera body upside down). I’ve never had to do a wet or dry sensor clean. It’s best to avoid getting the sensor dirty in the first place.

Dood
That puff of wind is about the worst thing to do. may clear the sensor but also more likely to stir up more in the camera body.

Google says:

Yes, you should use a blower for camera sensors and lenses to remove loose dust, as it’s a safe and effective method to prevent contaminants from your mouth or rags. Hold the camera face down or at a 45-degree angle, giving the sensor a few gentle puffs of air, and never use canned compressed air, which can spray harmful propellant onto the sensor.

Google doesn’t clean sensors, people do. I have been cleaning my nikon camera sensors for at least 20 years. Yes I have used and got a blower but very reluctant to use it having made a one time error and stirred up dust making the camera sensor worse. Been there and got the result.

when travelling, ie going abroad, I have on a couple of occassions had to resort to either one of these which is always in my camera bag which takes up no room

I soon learn’t not to take a rocket type blower as custom officers threw a wobbly thinking it was a !!!
there are times when one changes lenses to suit a particular shot. Not easy in Egypt with all the dust flying about.
