Using K10D to copy slides ?
If you get a copying attatchment for your camera from e-bay or similar, they will work. quite well in fact, but will crop the image owing to the APS format sensor on the K10D and you will not be able to copy all the slide, same applies to bellows too. If I only have a few I just tape them onto a win...

Can any one explain.....
a little chromatic aberation (ca)is normal with digital. you'll notice it in high contrast areas of your images. ie green leaves against an overexposed sky....or in your case, bright overexposed highlight against a dark pupil. different colors of light have different wavelengths and will bend throu...

Can any one explain.....
In certain lighting conditions, purple fringing is common to most DSLR's and has very little, if anything, to do with the lens. This phenomenon is a function/limitation/inability of the DSLR's sensor to properly resove high contrast parts of the image. Given the same lighting conditions almost an...

Hello Again
Hi Tim, scary.. I was going to post an almost identical shot taken from the battery Bank Holiday Sunday.. but the sensor was too dirty, and the picture wasn't enough of a stunner for me to be bothered cleaning up the image. I'm guessing that was taken Saturday.. the weather was horrible on the S...

Exposure
I don't know how much you have edited those images. What you really need to do is upload an unmodified image and one that looks right on your screen. Then we can compare them and see if is the K10D underexposing or just your monitor which is too dark. Do you have a CRT or an LCD display? CRTs can...

Exposure
Do you have a CRT or an LCD display? CRTs can be calibrated using patterns and don't need a hardware sensor. using software solutions you get a rough calibration of a screeen, which is usable but using a hardware solution will yield much better results.

Pentax Sensor cleaning Kit..
Hi all, I bought the above earlier in the week.. (scroll down) http://www.srsmicrosystems.co.uk/index3.asp?id=574§ion=Pentax&set=3# No complaints about delivery from SRS either.. as usual. :D This is a dry cleaning kit. I haven't used a wet cleaning system before so I do...

Pentax Sensor cleaning Kit..
Was having a look at that for thorough cleaning. I have the Arctic Butterfly SL700 as my 'quick' and 'field' cleaning tool. It comes with a case (and an other inside that) in which you could easily fit the bits from their wet cleaning kit or the Pentax dry kit. I highly recommend the SL700 (or th...

Kodak boosts digital camera sensitivity
Sounds interesting. Pixel patterns In nearly all of today's digital cameras, each sensor pixel detects either red, green or blue, with those particular colors placed in a quasi-checkerboard arrangement called a Bayer pattern, after the Kodak engineer, Bryce Bayer, who developed it. Every secon...

Nice idea, but it reduces the real resolution of the sensor further... Doesn't that effectively happen with noise refduction algorithms anyway?

Kodak boosts digital camera sensitivity
unless I misunderstand how these filters work, the colour filters are physical gels which cover a pixel, and they are basically a part of the sensor. You'd basically need interchangeable sensors to be able to swap them.

Kodak boosts digital camera sensitivity
I can imagine some CA problems due to the arrangement of photo detectors of different colours. From looking at the diagram it takes 16 photo detectors to generate one pixel, where as currently you only need 4. This means you'd need a 40MP sensor to get the same resolution as a current 10MP sensor. S...

SD Card
Hi All I've noticed that on my DL2 i can get 93 RAW and 341 JPEG images. But on my K10D i only get 62 RAW and 205 JPEG why is this. I'm using a Extreme lll 1gb card 6/10 = 0.6 is approximately the ratio of the number of pixels in the DL2 sensor to the number of pixels in the K10D sensor. 2...

Program Line
let me use an analogy, with booze. think of a proper exposure(at any given iso) as a combination of aperture, shutter. now pretend you're mixing a black russian. You got vodka (say aperture), and you got kaluah (say shutter) that your going to mix (porportionally for any given sized glass). d...

Filters
My guess is that you are not going to see much vignetting using a P series on the 18-55. Don't forget that the digital sensor is significantly smaller than a film frame (which is what Cokin are talking about when they mention focal lengths). And the filter size is a mere 52mm. G

Un Branded....
Rae000 I certainly wasnt intending to lynch you either, and I am sorry if I gave that impression. It was meant as a serious question though, as I understand that digital sensors are far more susceptible to stray light ruining a shot than film is. I know it is too easy to get paranoid about t...

Refelective Lighting
I need a couple of slaves to hold up polished gold mirrors for me, I can't find either :( My approach to light? My lenses force it to 'there isn't enough getting to my sensor' :( :lol: . Mine, I don't actually have a clue at the moment. I can get composition, Dof, framing, etc, but light still el...

CAPTURE ONE LE - SanDisk Freebie
I don't know how many flavours of DNG converter there are, but I certainly have one called "Adobe DNG Converter.exe" which is a small, stand-alone Windows program with a typically unintuitive Adobe interface. But it works. G Really, I thought being an Adobe thing it would be a plug-in ...
