correcting white balance in raw: loss of quality?
I think the Raw file captures what the sensor saw - the colour balance is applied after that so I don't see how quality could be affected. I was thinking: because the sensor "saw" colours with a certain colour temperature. Maybe that could affect the quality of the final pic, if you have t...

in camera hdr
my first serious attempt at using the k10's multiple exposure feature. Interesting experiment. Interesting to note the banding in the sky. I can see two distinct cyan bands, which I presume is the clipping in the sensor that happens just before a part of the frame is completely burned out. Ex...

in camera hdr
AFAIK, using Multiple Exposure in this way will only complete the first step of HDR photography, that of capturing the dynamic range. But the dynamic range can't be anymore than that of the sensor, which would be the same as just doing it in one exposure. :? I fully understand HDR when using seper...

Sensor cleaner
I've just found this: http://www.cameraclean.co.uk/acatalog/CCD_Cleaning.html third one down - the Speckgrabber Pro. Seems like an economical solution, what do you think? :?

Sensor cleaner
as a working pro.... Careful handling is the first line of defence. (ok not everybody has multiple cameras and can avoid swapping lens in the feild, or grab a canon g5/pro 1 to go where my beloved Pentax's may perish). I consider a rocket blower to be the second line of defence. anything th...

Many seem to prefer Rocket blowers and the like but blowing the dust somewhere else inside the camera seems like a bad idea to me :?

true, if that's what you're doing, but if you hold your camera upside down, while cleaning or whenever you remove the lens, gravity helps you out.

K10D with Sigma 17-70mm f2.8? plus Jessops 360AFDP Flash
The P indicates Pentax fit. The flash would read AFDC or AFDN for the other two variants. The flash is titled 360 AFDP, written on the body above the red focusing light/IR sensor. The flash appears to be fully conversant with the 5 or so different flash modes accessed via the 4-way rocker at the ...

Refocus!?
Looks like bracketed focussing combined with psuedo-video to me. Most definitely not ;) I remember looking at this a while back - it's extremely complicated and is completely different to what you would consider "normal" :) As far as they say - you can achieve it with a different type o...

Refocus!?
To get a 6mp image out of it, good enough for printing however, the sensor would have to be ridiculously big! Think on the terms of, large format version of a digital camera, increased in size!

Sun Light Entering Viewfinder
Hi Mac, I guess it is the same with Dslr's. The pro camera's still have these nice lever's to close the viewfinder. And i think the lightmeters are basicly the same as in the pre Digital years. The only real difference is the light beeing captured on sensor instead of film. Or i am completly blinde...

Focus Bracketing
Following on from the Refocus thread, I've just remembered that there was a thread somewhere a while back that suggested Pentax had filed a Patent for an anti-shake mechanism that also moved the sensor backwards and forwards??? Perhaps this is part of a focus bracketing mechanism? :shock: If th...

Weekly Competition No. 39 - "Wildlife"
Daniel, that is the meanest looking ladybird I have ever seen!! good capture! :D It looks as though it's about to fly, but it was just cleaning its wings, so it sat like that for a minute or so. But it is my favourite ladybird pic so far... Found it hard choosing an entry this week, as it's my...

Samsung GX20!
This info begs a question . . . Does Pentax design/manufacture for Samsung, or is it Samsung designs/manufactures for Pentax. If the former, how on earth did anybody get permission to release this Samsung info ahead of Pentax? CMOS sensor too, CCD ditched.

Samsung GX20!
http://www.photomalaysia.com/forums/showthread.php?t=40022 The above link implies it's a Samsung designed sensor, and therefore that Samsung had a big input on the development. Fair enough. We use enough Samsung parts - NAND flash particularly. I don't actually care who designed it - just tha...

help with raw
You can think of Raw as being like a film negative and Jpeg as a film transparency. You work from the raw file/negative and it is never altered but your 'print' is manipulated in whichever way you want. Keeping the original JPEG unaltered can be achieved in the same way you keep any other file...
