UV filters do block UV but the lens coating and the filter infront of the sensor also cuts UV so in the end they hardly make a difference. But hopefully the more powerful ones do make a difference though.

Tuff question
Extract from Pentax Forums: - Metz 58 and HSS It has been documented that the Metz 58 AF-1 flash unit does NOT function as a controller/master when trying to wirelessly activate a second, off-camera flash in High-Speed Sync. However, the Metz CAN be used as the HSS slave. This seems to be a bug,...

Enhance eyes in Photoshop
or should that be, "Enhance eyes in Photoshop cheating" So using reflectors and extra lighting, including fill in flash, etc is also cheating? I draw the line at cloning in or cloning out ( apart from scratches on negatives and sensor muck ), but altering contrast amd digial dodging and burning ...

Black Pixel
I'm getting a black speck on my photos. When I zoom in it looks to be one black pixel. It does not show if you do the dust check (the sensor shows up as perfect)only on a photo. Have tried a different lens and still the the same result. Anyone any idea what this may be please.

Black Pixel
There may indeed be a dead pixel in your sensor. I think it is not uncommon and maybe not surprising given how many millions of them are out there! I believe most (all?) pentax DSLRs have a 'pixel mapping' function in one of the in-camera menus which basically tells the camera to render such pixels ...

Which armour for my K5?
What do you do to it, all my gear is pretty much unscathed? A quick rub with a brillo pad is quite effective in adding scratches. For a more dramatic appearance try using sandpaper. Hope this helps, David orbital sander is much quicker and as a bonus if you leave the lens off you can get lots of d...

Also here: http://www.laserist.org/camera-sensor-damage.htm :shock: But what did it do to people's eyes at those concerts?? Seems to be the original thread - appears those shows were using incorrectly set high power settings which would have damaged retinas too :( Matt

Maybe it' a design flaw in Canon 5D Mk II?:twisted::twisted::twisted:

Not just 5D Mk II: I work in a laser lab at Johns Hopkins University, and I can say that Frank doesn’t know what he’s talking about. It’s not a specific brand or sensor problem, it’s a simple energy density/flux issue. The materials used in every CCD or CMOS sensor are essentially the same, Silicon...

Makes you wonder about the Pinpoint doesn't it? What if someone is using one across the room from you and your camera?

but I’m guessing the roadie or DJ operating these lasers doesn’t comprehend the dangers involved That's no excuse in my book. There has been enough publicity over the last decade and more regarding all types of laser products that anyone professing ignorance (before or after the fact) should be tre...

I'm with Bernard on that. Especially for people in an industry where laser usage is widespread.

Certainly for major concerts and festivals all lighting, including lasers is done by qualified lighting technicians - who have been trained in the use of all lights, including lasers. It is not something which any odd bod can do. Yes they may have grunts who hang the things up for them but the contr...

Firmware update for Ricoh GR DIGITAL III
Interesting to note that have announced the GR Digital IV. Ricoh has taken the opportunity to introduce numerous enhancements to the GRD IV. As you might expect, there's an updated image processor that Ricoh is using to wring more out of the sensor. Beyond this the most notable addition is an ima...

Not a K-5 sensor problem...
I had some palpitations over this one, I can tell you. I imported the early exposures from my K-5 into Picasa, which I use for organising photos. Here's a DNG as it appears in Picasa, and also if you upload the whole frame to Picasa web albums: Look in particular at the top edge: Here...

There was a post a while ago about Picasa and some edge corruption. Not sure where it is now but it has been mentioned before.

This is purely about Picasa not being able to understand the data fully. It isn't a fault and can be cropped out. Once Picasa update their software it should be OK. They just have a lot of different file types to deal with.
