Blown away
Ended up getting a job over by my local Calumet at the end of the day :wink: - real friendly bloke in there and I've bought quite a bit of gear of them. Anyways I ended up playing with the D300 and this guy pulls out a couple of A3 prints on fine art paper - well I says they look fantastic - yep...

what is the difference between..
Doesn't the K200D have no weather sealing, smaller buffer and less controlls than the K10D? Otherwise they are based on the same sensor so are quite a nice choice. I'd personally rather have the K10D as you can get the extra accessories, have the weather sealing, better controls, better viewfi...

No budget, in need of IQ advice
Just bought my K10D with Sigma 17-70mm. I'm getting my head around the camera (having made the leap from the manual world with a brief stop off with a 1MP Canon powershot). The camera is good. I'm okay with the steep learning curve. Being able to zoom in on eyebrow hair is nice. Not sure if I'll ...

RAW to TIFF
Ah, I see. I have Corel photopaint which I use for that sort of purpose, like removing marks when I have a dirty sensor. Is that what you mean?

RAW to TIFF
I have just been learning CS, and what I have been doing is to save as PSD after my RAW adjustments. Then I usually go to do some other adjustment layers, and cleaning it up. I usually save in TIFF or PSD before and after I flatten my image. I only make jpegs for saving on the web or emails. I ...

RAW to TIFF
I'm probably revealing some deep seated ignorance here but I thought that any image saved as JPEG had to go through some software algorithm to take the RAW saved from the sensor and create the JPEG file. I'd have thought that a hard coded algoithm in the camera would almost certainly be less capa...

digital cover LCD screen protector
I've just purchased the Giottos screen protectors from Warehouse Express. Using the Warehouse Express Product code numbers the PJP67 fits a K10D and the PZD78 fits a K20D. I've only had them since last Thursday so cannot give any long term comments; but impressions so far are : They were ea...

Bubble Level
Got me thinking, Is there some standard that the bed of the hotshoe on a camera is exactly perpendicular to the film/sensor plane? I've seen these little gadgets in the past and never thought they would be accurate enough. Some top of the line tripod heads have levels built in, ensuring that t...

Noise cancellation
Isn't noise cancellation where you take a black picture and subtract that from a long exposure to remove noise/interference at the sensor to give you a cleaner picture?

Noise cancellation
During a long exposure your camera's sensor generates a certain amount of electronic "noise" that will show in the photo. By having the long exposure NR switched on, your camera will take two shots; the first as normal and the second using the same parameters but with the shutter closed. ...

Actually pentax lenses, corectly, are marked in the actual focal length. This remains the same for a lens regardless of what format you put behind it to receive the image. Now imagine that the image circle projected by the lens is as big as we need for anything, just for a moent. Let's say that's...

Maybe not directly in relation to your question... but you also have to remember that there is more to it than just field of view. When you say, for example, 50mm you are defining a set of attributes of physics that do not change because of the sensor you have behind it. One such attribute is yo...

So we are probably stuck with 35mm equivalent for a while yet. Having used 35mm since 1984 that is fine by me... It's actually got nothing to do with 35mm. A 300mm lens is a 300mm lens, no matter what size the image sensor is, be it 645, 6x7, 35mm or APS-C, or any other. The confusion, if you can...

Designed for Digital or not
Previously when a new format for film has emerged, such as 110 or 126, then no-one has batted an eyelid over the new focal lengths needed. The reason it's become an issue with digital is that there are so many different sensor sizes, so the standard lens for each one will be different. Quoting fi...

I'd really like to see an end to this '35mm equivalency' stuff, some of us move between formats several times a day and can know which lens is wide and which is telephoto in any given format. Its just patronising. I agree, since the focal length is an actual measure within the lens from the optical ...

Pentax Optio Z10 problems at high ISO
what you are seeing is essentially a limitation of compact camera design, and one of the reasons most "serious" photographers end up with a DSLR. Modern compact digital cameras cram an awful lot of pixels onto a very small sensor, and that is a recipe for high ISO noise. You can un...

I love my polaris flashmeter. It's cheap, acurate to 1/10 stop and can be calibrated to match your sensor! it has a pc socket, and can do incident and reflected settings for corded, cordless, flash and ambient light readings. I tested it against my photo instructors sekonic (costing 3x as muc...

Found what was causing the confusion... The unit was set to display only full stops so it was rounding the values. I had to set the unit to the default settings which use 1/10th stops. I will now start to test and experiment if I need to give the Minolta an offset or not to match it to the sens...
