FILTER QUESTION PLEASE
Hi guys, I've been looking at the Cokin filter system for my K10. Regardless of what filter system I end up with I initially would like to use a grey gradual density filter and a smokey gradual density filter. Both to use for landscape pics. I generally use my manual lenses and on occassion the kit...

FILTER QUESTION PLEASE
Hi Deryn, Different sizes of holder hold different sizes of filters. Once you decide which size of filter you want get a cheap holder of ebay. The larger the filter size, the less chance of vignetting for a given lens, however prices of filters increase steeply as they get larger. You should rem...

Thought this might help. This main screen on the back of the camera is accessed by just pressing the INFO button. If SR was the last option used just press info, and turn the rear dial, done. Whilst here you can also set other options up quickly, like a favourites screen. From top left to...

Photoshop can do a lot for your pictures but it can't correct for some things. How many contributors here use polarising filters and UV filters? I have some potentially very nice pictures taken in the Pyrennese but they have suffered from the effects of haze. What are your thoughts about using a...

UV and Skylight filters are useful at high altitudes to reduce excess blue and haze. I don't use them all the time for protecting the lens though. Certainly use of filters where they are needed is a good idea. Lots of filter effects can be done in Photoshop, but obviously not those that demand...

UV and Skylight filters are useful at high altitudes to reduce excess blue and haze. Also still today, many coatings cut down UV light and also the screen infront of the sensor has an UV coating so had an UV filter still effect like it had in the film days?

It struck me that, bearing in mind the possibility of doing much more useful correction 'at home' with digital, a filter could introduce much more 'top cut', to get rid of the scattered UV and violet (even), and yet you could still do some compensation to get the colour balance right. All that woul...

Now I've thought about it, I would expect a whole new set of filters to be on the market 'specially' for digital cameras. Manufacturers don't usually miss a trick when there's a possible new market. Perhaps there are some and I just haven't spotted them. Uv filter will do that and always has but sin...

I carry UV (always on the lenses), a polariser, NDs and ND grads. Basically to do all the things you can't do in software. But I still have my red filter (screw mount) for my B&W film. One of the great 'digital filters' is the infrared - by effectively placing the filter in front of the sensor,...

One of the great 'digital filters' is the infrared - by effectively placing the filter in front of the sensor, not the lens, you can still see through the viewfinder normally. This would be theorhetically possible with a film camera, but very impracticle. And here comes one of the problem with mode...

And here comes one of the problem with modern sensors, most of them have en UV coating on the sensor screen so they block Infrared light so you need to replace/remove that as well... Surely a UV filter blocks UV light:?

Sensors are very sensitive to IR and the scattering of IR light would detract from the image, so most cameras have an IR blocking filter. Depending on how strong this filtration is depends on how effective the camera is with a IR filter over the lens (one that allows only IR light) DSLRs can b...

As I read this the adverts have very cleverly picked up what we are discussing and have put the big advert to the right. There is a page showing how to DIY this on a D50. They describe taking out a 'hotmirror' filter (IR blocking) and putting the IR filter in. Worth a read... EDIT: The "h...

Yes, that's true. The point is that you need some glass there to replace the removed filter.

Polarising Filters
Looking to buy a replacement polarising filters - a 52 and a 67mm one. I have heard it said that it is best to go for a more expensive, main brand filter (rather than the plethora of £3.99 ones on fleabay) but is this truly correct... bearing in mind I am an amateur on a budget... Anyone willing to ...
