Filter, or not?
I think I'll do the same. Only problem is that if I use a UV filter with a screw in polariser I get vignetting at the wider end of my 18-250 Pentax lens. :cry: Guess I'll have to slow down as appropriate!! Take off the UV filter and screw on the polariser. Unless it's an action shot I'm advised t...

Light proof glass filter fixing
I have just bought some glass to put in front of one of my lenses, I will probably use a manual 28mm. The glass is size 4 1/4 x 3 1/4 inches. Any suggestions how to stick it onto the lense so it is light proof? I was thinking of a circle of bluetac.

I don't think I would trust Bluetac, unless you use a lot of it. But what is the glass for? G

It is glass for a welding mask. The idea is to get a super long exposure from it.

Ah. Neutral density. Your heading said "Light Proof Glass", and I was wondering if you were trying to re-invent the lens cap. G ETA: If it's just temporary, then Blutac is probably just the thing.

Yes it's a cheap £1.30 10 stop ND filter in essence. I just need to figure out a light proof way of fixing it on to my lense.

Bluetak sounds good if you want to remove it later. If not what about bostic or similar?

I'd go with blue tack....it works a treat. I used it to fix a polarizer to my lens for a long time :oops:

Yes it's a cheap £1.30 10 stop ND filter in essence. I just need to figure out a light proof way of fixing it on to my lense. If the standards are the same in England as they are in North America, a #10 welding glass is not exactly the same as a 10 stop ND filter. The ND filter won't "kill" the U....

It is glass for a welding mask. The idea is to get a super long exposure from it. I have a bit of welders glass; I used it to photograph the partial eclipse of the sun in August last year. It's smaller than yours, but Blutac to the Cokin filter holder really well. The optical quality, is, ho...

Cheers chaps, will try bluetack I think then. As for optical quality, I am expecting a lo fi result which is possibly part of the appeal. We will see. I'll post images.

Be prepared to do some major white balance adjusting. Otherwise, you will have the strangest colors in the photo. I use this kind of glass on some of my scopes for shooting the sun.

Why not Araldite a Cokin P series, or perhaps A series screwed Adaptor Ring to your piece of glass. Just choose the thread diameter of the Cokin Adaptor Ring to suit your lens.

Silkypix wont open RAW file
I was sold on the Samsung-badged Silkypix that came with my GX20. Mainly for the image quality as others have pointed out. However, since downloading Lightroom 3 I have to say that I will be (am) switching. This is simply because post-processing is much more than just raw conversion and LR3 cover...

Censor cleaning
After a lot of reading and flipping a coin I bought wipes from ebay and Eclipse fluid. With much trepidation I cleaned the sensor. It did say a single sweep which I tried and didn't manage. So three wipes later it was clean. The wipes seem to be glue applicators from primary school with a pec pad...

"resilient hair" on pictures
Hi Shine, And welcome - sure you'll enjoy using your K-x - once you have removed that hair. It is most probably a bit of dust that has got in somehow. And no, the dust removal does not rmove everything. Have you a rocket-blower? (One with a valve so that you don't blow more dust onto the sensor!...

Cold exposure tips (no pun intended)
The K-7 is "cold resistant" and is designed to be operated at temperatures as low as -10°C. See www.pentaximaging.com/slr/K-7/ It maybe - but try taking it from a nice warm hotel room at 20C straight out into the -10C cold snowy weather. Condensation on the lens/filter and viewfinder. Keep it...

Cold exposure tips (no pun intended)
I'm not so sure about that. Warm air when suddenly chilled will condense water. So the warm air inside your camera body and behind the lens filter, nicely warmed up from being inside the house, will condense water if suddenly chilled. It might not be much water due to the limited amount of air in th...
