Infra red filter?

That Company in Norfolk is near here. I can check them out for you if you're considering using them. Alternatively just do that remote control test and see if you'll get the results you're after :D You could ask them for a discount. £250 seems a lot of money to me.

Infra red filter?

A few months back I had the idea to take some shots with my K10D and a IR filter from my P-system. As you probably guessed - it never worked out very well ;) The K10D sure seems to block all IR light.

Infra red filter?

The *istDS worked well enough for IR, but the K10D has a much stronger filter and is not good for the purpose.

Infra red filter?

i think its possible with patience, I found this one on flickr, 5 minutes exposure. I really like it, probably a rock solid tripod used too. As far as i can tell this was taken in a K10d not modified.

Infra red filter?

The alternative to moving the sensor is to use an old manual lens which has a small red mark on the focusing barrel which is the offset for using IR. It appears on Super Takumar, Takumar, M and A series lenses. I don't have any F/FA/FAJ lenses to check... Best wishes, Kris.

Lightroom

Lightroom2 brought the graduated filter. I use that a lot. You can select which editing feature you want it to perform--exposure, brightness, contrast, saturation, clarity, or sharpness--and move the curtain.

live view

And, just about all manufacturers claim the number of SUBpixels of the LCD display and not the number of pixels. Normally a pixel in a LCD panel has three subpixels (red, green and blue). Camera manufacturers have a nasty habit of using the number of subpixels (marketing dept. again) that also c...

Anyone else waiting for their k20d?

Probably a lens with a 49mm filter thread - easy mistake to make and 49mm is a common size with Pentax lenses.

Infra-red on the K20D

Hi All, I'm interested in doing some infra-red shots, and have a screw-in IR76 filter to start out with. Any of you have any advice for a complete novice?

Infra-red on the K20D

The K20D is not the best Pentax DSLR to use for IR images due to it's built-in IR filter. Canon produced a 20Da model specifically for astrophotography. The normal IR filter which sits in front of the sensor is replaced with, near as dammit, plain glass to show the predominant red coloured clouds...

Infra-red on the K20D

Personally I find that the longer exposures add to the surrealism of the IR's. I found getting the exposure right the 1st few times the hardest. I thought it was bright enough but you really have to push it till you start seeing whites or close to atleast. back yard testing is good for that. ...

Infra-red on the K20D

Unprocessed RAW v JPEG print test

RAW stores information in a different way. Essentially RAW data consists of the light values of every cell on the sensor (essentially they are grey values). The RAW file will probably store the configuration of the Bayer filter as well so that the RAW converter can convert and interpolate the light...

My inherited Lenses - any experience with the K20d?

I've also inherited an old 2x adapter to double the focal length on all of these lenses... i'll use it with caution, as i'm guessing it my filter down the quality, but it could be useful in certain circumstances. And the flashgun i've got is a National PE-2057. This any good for use with the K20?

My K20D will be arriving tomorrow!

Can someone just push a FF button or something??? With it will be the 18-55M KII and DA 55-300. I've already got an additional memory card, polarising filter for the 18-55, skylight filter for the 55-300 and spare battery. (Battery Grip next on the shopping list, and shortly after a 50mm 1.4) ...

A bit of a joke as the Olympus as one good think the HOYA filter on it, so you are giving them some funds.

My K20D will be arriving tomorrow!

I use the eyecup on my K10D after someone here recommended it (John Riley I think) and yes, much better than before but still tiny compared to the LX. A useful addition, all the same. I'm sure you are right Kris but you have to remember I'm used the E-510 VF :wink: A bit of a joke as the Olympus...
