My first *ist-D Sample Photos
Hello all!! I was away for a while due to an extremely tight schedule and deadlines at the office (you know I.T. work ;) ). I came back to visit the forums and wow... how lively the discussion was!! I've noted a lot of useful info from the last several posts. To the guest who addresses a q...

Focus Fixer
Hi All! I had taken a shot with the *istD that looked great on the LCD, but I realised I'd mis-focused. Found a link on ephotozine to FixerLabs, and tried the FocusFixer. (I know, I didn't believe it either!) http://www.fixerlabs.com Results are here: http://www.pbase.com/mattmatic/gallery/fo...

That worked really well Matt. Good example.

Thanks Matt, It sure is a great utility to have. I just wished I can get a trial version :) Looking at your sample photos, the result is impressive. Shotgun

*ist D bad pixels
As revealed in another thread, I'm on my second *ist D, the first had a bad clock. The current one has three annoying stuck pixels, one red, one blue, and one white. These show at all normal shutter speeds, I've not tried excessively long exposures where these things reputedly get worse. Shots I ...

*ist D bad pixels
I've been refraining from further posts because I keep doing more tests. Dark subjects certainly appear to be a key factor. I have established that there are four sensor problem areas and that the file format, ISO rating, shutter speed (short of burning everything out!) all make no difference. Th...

*ist D bad pixels
Hello Malcolm, Just a little anecdotal evidence which, I think, will back up Matt's comments. "Stuck pixels" have featured a lot recently in my wanderings. Among my other vices is that of "flying" MS Flight Simulator on the PC. Recently a number of the members of the PC Pilots' Club of Ireland...

*ist D bad pixels
Hi Malcolm, Just a quickie to say that I hadn't seen your post timed at 10:06 before composing my "tome" But, yes, I think you may be correct in saying that SLRs of the digital age may not give us as many years of service as our old windie-uppy and auto-focus film SLRs.

*ist D bad pixels
Hi Lurach, I too gave the 'first generation' issue some thought but I decided Pentax were not new to digital and not new to SLRs either so the problem might be small if there was one at all. I remember my LX was 'first generation' back in nineteen eighty whatever it was and after fewer than 12 mo...

Hi, I had exactly the same problem, hot pixels appeared in more or less the same place as in your camera. I returned the camera back. Regards, Ivan, Moscow

*ist D bad pixels
I too know the headaches of bad pixels. I realize it's not the same camera, but I bought a pentax optio 33L about six months ago, after the first week I noticed 2 bad pixels, so I took it to Pentax Canada, which is convieniently down the street from where I work. They fixed it no problem. 4 months l...

*ist D bad pixels
Shawn, Sounds like the Pentax guys gave you a hard time. However, all in all, it's not really Pentax that's at fault (just the fact they didn't recognise the problem). Any manufacturer of digital camera will have the same problems - and the response from each company will certainly vary ;) Ho...

Sharpening in Photoshop
Sue and I ran a beginner's digital night recently down at the ADAPS clubrooms and one of the things we did was test three types of sharpening. 1) Unsharp mask directly on the RGB file 2) First converting to Lab mode and applying unsharp mask to the lightness channel, then converting back to RGB...

Sharpening in Photoshop
John, I always enjoy a challenge :) Thanks for your suggestion - just trying out the methods made me sit up and think. Also, I took a good long look at Russell Brown's site. He has some superb tricks for PS. Even the sharpening one "Advanced Sharpening" is brilliant. Watch the video, but it wo...

*istD compatibility & FAQ
While anxiously awaiting the arrival of an *ist D I was commiserating with myself that the 18-35mm FA J lense would not be of use other than on the * ist D - lack of aperture ring on the lense!! This afternoon I got a call from my friendly dealer and, at the speed of sound, I presented myself at ...

Startup fault with Optio 550
My first, and now my second Pentax 555 have developed the problem of the lens failing to retract completely when turning off the camera. With others here reporting the problem I think this will turn out to be a very serious problem. When it fails to retract completely, you can't turn the camer...

Startup fault with Optio 550
Hi, I have experienced similar problems with my 555. Someone in our household had switched it off and the lens retracted but the cover remained open. When I tried to switch it on the start screen came on, the camera beeped and shut off. As an experiment I pressed the on button and the review butto...

Pentax Optio S- User feedback
Hi, I think my Optio S is great, the only thing I'd change (improve!) is the response time from pressing the shutter release, to it actually taking a picture. Even on fixed focus, no flash, it's getting on for 2 seconds... :( ...unless anyone else has one, and they don't have the same problem...

Infra Red on istD?
Don Schoolmaster, The other fact to bear in mind is that the Dimage 7 uses phase focussing (I think) - by reading information directly off the CCD. Hence, any sensitivity in the IR range will allow it to focus. The *istD, on the other hand, has seperate focussing, as in all the film versions. ...

Digital ISO
Hi! The final print size and the ISO rating are not directly related ;) What stops you producing great prints is the image size. The *istD is 6.1mega pixel, giving an output image of 3008x2008 pixels. If you print at 20x16" that will give you about 130 pixels per inch. It will look great inkjett...
