How to use the Colour Balance control on a DSLR
I suggest that different lenses have a different field of view so the base their analysis on a different set of samples of the scene. It could also have something to do with the different levels of UV getting onto the blue sensor? In this case the lenses were all 135mm or zooms at 135mm. The coatin...

Haze filters and DSLRs
Wow you did your homework :) I believe most sensor have an UV coating on their protection-screen so those will probable be specialize for digital. I self use Polariser filters to cut haze.

How to take amazing space photos
All in all he did make 44 exposures of around 15 minute each. 11 monochrome 11 green 11 red 11 blue (seems a bit high though 44x15 = 660min = 11 hours.) So yes I think it's possible to get too much details if you make so much exposures. What we are getting with our camera's is truly only ...

And the Nobel Prize for Physics 2009 goes to...
Willard Boyle and George E. Smith, researchers at Bell Laboratories in Murray Hill, New Jersey, will each receive a quarter of the ten-million-Swedish-kronor (1.4-million-U.S. dollar) 2009 Nobel Prize in physics. Canada-born Boyle and Smith, a U.S. native, invented a sensor for capturing digital...

On time, K200D
Hi, I want to set-up my camera and pre-focus it on a birds nest and take the shots using my "YongNuo RF-602 wireless trigger" when the birds return to the nest. I'll be using a separate battery pack to power the camera as it may take a hour or so before an opportunity presents it's self. I hav...

The sensor is not actually active until it's capturing an image so it's not going to overheat. Making a 12 hour exposure might cause it to overheat, but power on for that length of time will not. Cameras with a CCD sensor are more likely to overheat faster than the newer CMOS equipped Pentax came...

I think what Greg is saying is he doesn't want it to go into sleep mode. ? I think the sensor would only heat up if its active for a long period of time, such as in bulb mode. but if its just sitting there with the power on and waiting to trigger, it shouldn't get hot at all. Could be wrong too I...

On time, K200D
On my older *istD I have taken many sequential sunsets with an image every minute for an hour - turned camera sleep mode off and then sat there with stop watch and remote control. Never any problems with the camera and the sensor on that is still as good as it was when I bought it in Tokyo.

Gigavision sensor?
New wind is blowing through digital imaging land, hopefully it's a breeze which isn't too cold or too hot and has a nice smell :) Today we have the CCD and the CMOS sensor, both work very well but surprisingly they are analogue devices. The signal that from the sensor needs to make a trip around...

And how much memory will be needed to store those RAW files? :roll::roll:

Gigavision sensor?
Yeah gigapixels, the only problem now is that they need 100 pixels to make one pixels although like someone in the comments there said, the more light there falls the faster they cycle so if you count the amount of cycle you could use ever pixels on is own to get a grey scale instead of using 100 fo...

SRS Micro
I have just received an order from SRS Today, Just a couple of small items, But they were well packaged and quick, When i bought my DA 50-135 from them it arrived the following day, Personally i rate SRS as good as any of the top suppliers i have ever used. Plus they have a wider range of Pentax ac...

Ricoh mirrorless K mount?
Well that doesn't help my "Which shall I buy - Oly EP1 or Panny GF1?" dilemma... :? I quite like my Ricoh GR-D and something along the same lines but with a larger sensor and interchangeable lenses would suit me nicely. :)

Ricoh mirrorless K mount?
You've got me re-thinking small camera now!! Looked at the Pani and a couple of others. My back pocket machine at the moment is a wee Fuji EXR 200. Its not bad at all and the split sensor functions actually seem to work. Would like something that small with IC lenses. GOT IT! Pentax 110 conversi...

Ricoh mirrorless K mount?
Actually I could live with a fixed lens to be honest, I just want something that slips in the pocket but has a larger (FourThirds/Foveon/APS-C) sensor. The Sigmas look good on paper but are slow and cumbersome in operation, and the Leica X1 is far too expensive for what it is (the cost of red dots i...

I quite like the look of the Leica X1. Tiny little thing, but with an APS sized sensor. If only I had lots of money to spare... Cheers, /Ian

Quality in big prints
I have a picture I am particulary pleased with. I'm not sure it has any great artistic merit, but I liked it enough to want a big print. I should mention the reason I'm posting it here, rather than on another section is that it was taken with a Fuji S9600. I took it to the local 'Staples' store and ...
