Dust on sensor?
Artic Butterfly ordered ;) One thing that deterred me from buying a DSLR a few years ago was this dust problem :( But, if a little butterfly can cure it..... :)

Dust on sensor?
Should I be able to see it with the naked eye as nothing is visible looking directly at the sensor with a magnifying glass. Sometimes you can, but usually you can't see offending specks of dust on the sensor with the naked eye. If using a blower, just give it a strong blast to the centre or the roug...

Dust on sensor?
Problem solved! :) Is it Artic or Arctic? I always though an artic was a big lorry that bends in the middle ;) Whatever, the butterfly did it! Thanks all for your help.

Dust on sensor?
If you haven't resolved the problem yet try this. I recently had a similar problem after changing lenses in the Cambodian country side, covering my sensor in a thousand specks. Well, I mounted my camera on the tripod with the sensor facing the ground, opened the camera with sensor cleaning, stuck my...

Thanks Matt! The Butterfly blew it away but not planning to go to Cambodia, this week anyway ;)

Black and White Filters - Digital and Physical
What techniques do people use for recreating the look of black and white filters? There are a lot of techniques and plug-ins, and in-camera options, but I always struggled with noise in my black and white shots, esp the skies. I wondered whether restricting the actual light going to the sensor...

Black and White Filters - Digital and Physical
... to be honest I can't follow your reasoning. Those are both taken with digital right? digital sensor capture only! red green and blue light. This a good example how an sensor sees the world. So if you're using a colour filter infront of the lens, you will reduce the effectiveness ...

Laptop specifications
As a designer by trade (and hobby photographer) I see a fair amount of IT equipment, some good, some bad. Last time I looked Jigsaw24 were still selling the older (non-solid aluminium case) 15inch Macbook Pro at heavily reduced prices. We bought exactly that machine last November, upgraded to 4Gb...

Wild speculation about the next Samsung offerring
I thought Samsung were looking into micro-4/3rds as a next step, in which case it probably won't have a k mount. States on Samsungs website they will be sticking with an APS-C imaging sensor, so that rules out 4/3rds - wouldn't make sense to ditch their own sensor for a competitors!? That's for the ...

New Olympus
I would very much like to see the Samsung system first: an APS-C sensor and possibility of using a 40/2.8 pancake lens or even a 35/2 as "normal" lenses is quite enticing.

I would very much like to see the Samsung system first: an APS-C sensor and possibility of using a 40/2.8 pancake lens or even a 35/2 as "normal" lenses is quite enticing. I suspect few of us would part with cash for a second body, even a small lightweight one. What about a super-sexy, rangefinde...

using filters
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?

using filters
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...

using filters
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:?

using filters
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...
