I am trying to take an image like so many I have seen with an item on glass with a reflection. I am getting a lot of debris showing on the glass in spite of my best efforts at cleaning the glass.
Does anyone have any experience in avoiding or dealing with the problem? Thanks |

You might want to ask IreneM. I'm sure he would be very helpful. An anti-static cloth would help. That would avoid making the glass become a magnet for more dust which is what tends to happen if you wipe it with a regular cloth.
A framing site such as this one has other things you can buy to keep glass dust free.

Irene is a guy? ;)
I've done a few of these shots now and can say that it does require some meticulous cleaning and very regularly too, also a microfibre cloth is really good and will clean dust off and not just move it around. The other thing I have found is trying different positions for your lighting can work wonders and also the angle of the shot seems to give varying results too.
The snail shot below had one spec of dust in it and that was there from the time it took me to dust off, re-set up the snail and get back behind the camera - it was something like the 10th or 11th time I had cleaned the surface in 20 minutes.
The spot is just to the left of the snail, obviously basic editing so I couldn't remove it.

LOL. I was thinking of someone else at the time I was writing that.

| Thanks for the replies. I did use the cloth I clean my glasses with and that did help, but I still ended up with a couple of spots. It sounds as if there may not be a magic solution other than persistence. |

Angle of light.
Angle of the camera.
Both these aspects can make or break a reflective surface setup. I keep a fan on low speed on the entire setup too to limit the dust from settling. I'm also planning on using a water table, the ultimate reflective dust free surface. |

What would happen if you coated the pane of glass with water, perhaps with a bit of dishwasher detergent to encourage that "sheeting action," or perhaps used mineral or baby oil? |

What I did was I carefully poured water onto my light table and it puddled into the center very nicely leaving a wide area to photograph from. I place whatever object I'm working on in that puddle and shoot away on a dust free table. I have pieces of clear plastic I use to place the objects on so it looks flush with the water. I'd show you a shot but it'll compromise my current Smoke II entry.

I tried oil on plexiglass and it turned out worse than no oil. Whatever dust is floating around tends to get stuck to the oil and you can't do anything about it except start over, very time consuming.

| Yeah, dust is a real pain. When I do these reflections pics for basic editing challenges, I always have a spray bottle of glass cleaner and a microfibre cloth at hand. You have to clean the glass surface constantly. |
