Photography or Graphic Art?
... Sorry it's really confusing, could you enlighten it a bit? Lol, I'm not getting into a game of cat's cradle as we would still be here chewing it over till the middle of next week. A camera sees lumps of stuff. What we see are rocks, trees and grass which are not there, in fact, either in re...

My Favorite Focal Length for Studio Fashion
Everyone I know in the business have their preferences regarding focal lengths for different applications. I tend to work quite a bit shorter than most when it comes to working in closed quarters in a studio environment. I specify this for a reason. Studio work is a fixed space that you set up lig...

Sunny 16.
It was very sunny in my bit of Britain today, Stefan. I've known about the sunny 16 rule since I took up photography 25 years ago, but as I've always had metered cameras, I never bothered learning it. Ironic then, that now I have loads of metered cameras, both film and digital, and four handheld...

I haven't the slightest idea what Algi and Anvh are talking about. All that theoretical stuff is way over my head... No problems. I think we ended with an important thing though that you need to expose digital differently then film. You might have heard the phrase "expose to the right" here or s...

The problem with that Stefan is that the information is quite old now, and digital cameras have much more dynamic range than 5 stops. Probably more like 9-12 stops, dependinmg upon the camera. Like slide film, over-exposure kills the image with blown-out highlights, so be very careful about expos...

DFA WR prime lenses. Keep the midrange model K-7 sized, 10fps 16mp sensor with low noise and 1080 video. Announce plans for a FF sensor.

As the lens SR will still be active as the shutter is pressed..... Yes the body SR is still running, but it's in the body and maybe it cannot counter the shutter vibration and mirror slap, whereas the lens SR is independent (sort of) of this. The mirror slap happens before exposure so does not add ...

I'm happy with my K20D (although whenever I use my LX I marvel at the size of the image in the viewfinder). What I'd really like, as I have said before, is a tilt shift lens for the APS-C sensor so it would have to be about 17 or 18mm. If I could afford it I'd get the Canon version and a body to...

Canonites spoilt for choice?
Not really missing, after all I hav`nt defected to the dark side yet, but low light high ISO low noise for a start, higher resolution, larger file sizes so greater cropping ability, but this topic is not about sensor size. It is about choice, something a bit lacking in the Pentax range, just been r...

Cleaning K10d Focusing Screen Dirty
Hi guys Anyone knows how to clean a k10d matte focusing screen LF 80? Had bits of hair like dirt and some black spot, I took it out and accidentally dropped it (on our dining table). I have noticed a black dirt not sure if it’s a scratch but very distracting on the left corner and still have the...

Cleaning K10d Focusing Screen Dirty
I used a Rocket Blower on the K20D screen, came up spotless. http://www.the-digital-picture.com/Reviews/Giottos-Rocket-Air-Blower-Review.aspx Dust on the focusing screen shouldn't appear on your images, that would be dust on the sensor. Never touch the focusing screen wth your fingers or anyth...

Spyder auto-focus calibration
Would you test at max. or min. zoom? It depends on how well the zoom maintains focus over the range, so I would expect an average is about the best that can be achieved. Zoom lenses are fairly modest apertures, so hopefully Depth of Focus (at the sensor) will be enough to cover any residual error.

Canon develops giant sensor
I wonder what size body they will wrap around it? Non as far as I know they will not produce it for consumers... they might use it for the military and science.

I know that Stefan. Forgot to add a smiley. One thing it will be used for is telescopes.

Canon develops giant sensor
Maybe Gwyn, I at least haven't read about that only that it can film with 60fps under a full moon. :) And that it can be used video recording of stars in the night sky and nocturnal animal behaviour.

SRS Open Day - 9th October
Beautiful image Flossie, i like the lights in the distance. I myself almost never shoot over ISO400 and most of my shots are at ISO100, so very different use then what you do. It would be great if you can post those full sized later, but because it's a CMOS sensor i doubt it can replace the K10D...
