Lack of brilliance
I rarely use anything but RAW (old darkroom hound) but the couple of times I used jpeg, it looked just fine. I like the fact that Pentax has decided not to oversharpen the jpegs, you can do a better job with less artifacts in Photoshop. But since I'm used to taking a photo, then processing the r...

Green dot: dust or faulty CCD?
I've started to notice a green dot (actually more shaped like a +) in my pictures taken with *istDS. It's fairly in the middle of the pictures, and hence quite annoying. Advice from Pentax was simply to send camera back for inspection, and made it sound like dust. However, I thought dust would sho...

Green dot: dust or faulty CCD?
Thanks for the reply malcolmk. I've never had dust on my *istDS yet (touch wood), but found it hard to believe that this is how dust looks. Found Pentax's reply to follow their cleaning procecure in the manual (blow air onto mirror / CCD) an odd suggestion for fixing this. Guess the camera has ...

Lighthouse Pano
One important thing with panos is to use Manual exposure and make sure all the shots are shot at the same settings. Focus is another matter, but if there are different settings the photos won't mate together very well.

Lighthouse Pano
Here's an editorial I wrote up a while back, if there's still something you find a little foggy, don't hesitate to ask. STEP 1 Before anything, the camera work needs to be done accurately. Keep these in mind when shooting and make your PS work such easier: a) use a tripod with a head that pans ...

istDS, lenses and Astronomy
Hello Steve, I had intended to try some star trail shots but never got the weather when I had the time but what I have found out may be of help to you. When the Ds is taking a long exposure (B) the current drain is over 500mA and varying constantly around that value. Then after you close the s...

Pentax 1st DS raw and Adobe Photoshop CS, Help
I suspect that the .pef's produced by both cameras follow the same standards. You probably can use ACR. Try it and report back.

Fast Street Shooting with a Pentax DSLR
The "A" lenses were the manual focus "automatic aperture" lenses from Pentax. You can pick up 50mm A lenses (f1.2, f1.4, f1.7) pretty cheaply. Has the "A" setting on the aperture ring (next to the f22 setting etc). The "M" lenses are manual focus, manual aperture. Not really appropriate to your u...

Fast Street Shooting with a Pentax DSLR
Ted, The A series (developed for A series 35mm cameras such as the Super/Program A) and later lenses have electronic contacts that communicate with the camera (info varies depending on models), this permits the camera to operate in the various auto-program modes (AE). A lenses are manual focus, ...

The wonders of RAW
LOL! Thanks George :D Glad you're getting to grips with it all ;) The only other problem is the exponential storage issue... I am wrestling with RAW, TIFF, and PSD files in the gigabytes per month! Regarding exposure - you can claw back shadows, but only to a point. A full half of the values f...

DS2 in UK
Lenses with a "A" setting will enable use of all exposure modes. Pre-A lenses can still use metering, but in manual stop-down mode. Screw fit lenses, if put into M setting which stops down the lens to whatever aperture is set, will work very happily in aperture priority mode, but of course the...

New *ist-ds, built in flash problems
Thanks, I'm definitely sending the camera back on monday. I just tried the low quality settings for the first time and the pictures all looked like this... also, was experimenting with the built in flash and found that it only underexposes shots that are focused at a close distance, if I st...

New *ist-ds, built in flash problems
Yikes! Are you getting results like this in sunlight? Your picture looks terrible, though conceivably it could be caused by the camera attempting to compensate for the flash not firing. For this to have this result, you would need to have the camera set to adjust the ISO when there was not enou...

New *ist-ds, built in flash problems
Yes, I see. Unfortunately the data doesn't show anything unusual. However, is this how all your pictures are turning out, or just a few, or just this one? If it's all or several of them, then back to the shop it should go. If it's just one, then I wonder if some freak circumstance migh...

Pentax *istds or *istds2?
'subtle' indeed, the only difference that I'm aware of is the DS2 has the slightly better LCD monitor, as introduced on the DL. When multi-point AF was first introduced for 35mm, everyone made a big song and dance about it and how wonderful it was that you no longer needed to point the lens dire...

Sensor Cleaning
Ted, Late reply to your question. When a lens zooms or focuses, it enlarges or reduces the airspace between the back element and the mirror box. This means it is either sucking air in, or pushing air out. (The system is not airtight.) This means that the lens is forever sucking dust into ...

Ist DS Re-composition autofocusing problem
You could check that you have set the custom functions to centre spot autofocus, otherwise the camera will choose one of the autofocus points and this will change when you recompose. Very annoying and one of the first things to reset! With centre point autofocus you just point the camera at the targ...

Ist DS Re-composition autofocusing problem
I just came back from holidays and the DS really annoyed me during the time. The problem is with shutter-release button and auto-focusing. When I got focus on a foreground object (by pressing the shutter release halfway) and hearing the beep, and moved the camera so that I can shoot with the bac...

Ist DS Re-composition autofocusing problem
Hi John, yes I've always had the camera on centre focus, but when I recompose while still keeping the shutter-release half depressed, once I press the button, it again re-focuses on the centre. As for the low-light situation, I'm not fussed about how long it takes the camera to get focus....I kno...
