My first *ist-D Sample Photos
Lurach, To answer at least one of your questions... there is an FAQ page on the Japanese Pentax web site, and thanks to Altavista's Babelfish, this is what it said: Is the fact that ISO sensitivity is from 200 why? As for the CCD which has been used with the *istD being the sensitivity ISO200...

*ist D bad pixels
Malcolm, Thankfully I don't have any (yet). All digicams have issues with stuck pixels (yes even the Canons!). Some of the cameras can detect a stuck pixel, or profile their own sensor and map it out. AFAIK, pixels can grow defective too, so it's not a case of just getting a 'perfect' sensor. ...

*ist D bad pixels
Malcolm, Here's a link: http://www.starzen.com/imaging/ There's a tester for dead pixels for free. (Found the link from here: http://www.kernphoto.com/Resources.html - excellent list) Some say use dust & scratches filter, others suggest NeatImage, some say return the camera if it's in warr...

*ist D bad pixels
Malcolm, I'll try and add some insight into the behaviour you describe... CCDs in digicams are not what you might expect. Each 'site' in the CCD measures only light level, so a filter is placed over the CCD. Typically the filter is configured as a 2x2 square with RGBG - Red, Green, Blue, Green. T...

Infra Red on istD?
Unfortunately, the ist-D (in my tests) did not show sensitivity in the infrared range. There are many digital cameras out there that will allow infrared photography, but not the ist-D. I use the Minolta Dimage 7 with the hoya ruby infrared filter in front of the lens. I get fantastic infrared images...

Image size?
Ava, Photoshop can resize your image to any size, even a single pixel square ;) Image size and compression are two completely different factors. You didn't say which version of Photoshop you are using, but here's the general idea... Load your image in Photoshop. Select "Image", "Image Size" an...

Linear profile editing - better than USM, raw file support
Hi All! (Hope this isn't too geeky :) ) In playing around with PEF file conversion using dcRAW which can create 16-bit linear space Photoshop files, I've discovered some more very, very interesting things. Here's what you do: convert an image to linear space, perform USM within that colour ...

Scanning Images
Hi Lurach! First thing, I don't know whether there are any features disabled in the preview version (apart from the watermarking). I have the Pro edition - have had it longer than I can remember, and Ed Hamrick has been a star :) My general workflow for the Nikon Coolscan IV is as follows (whe...

Photoshop *ist D Raw Support
Ava, Definitely go for Photoshop CS. The learning curve is steeper than Elements. I have gone from Elements 1 to Elements 2 to Photoshop 5.5 to Photoshop CS. It's fantastic :) Here's a taster: healing brush (like an intelligent clone tool), colour matching between images, 16-bit image support ...

Filters for S/S4
Hi All Well, I've posted a couple of threads in DPReview and Yahoo Groups to see if anyone can help on this topic. Does anyone know of a supplier that does lens adaptors to allow the S/S4 to accept standard lenses (or lenses of any sort for that matter)? In DPReview (topic of the same name) me...

Filters for S/S4
Hi Well, I thought I'd bring those of you who might be interested, up to date, on the use of filters and lenses on compact digicams, in particular, the Optio S/S4. Using filters with the SRB Mount is a snip. When not in use, I loosen the two grub screws and fold the mount flat for portability....

Foggy pics from the S4
Pictures aren't even close to being that clear... After some reading I think the problem might be that too much UV light is getting into the cam lens. Pictures taken here in Calgary aren't foggy at all, So I am thinking it was too bright for the camera. (Could this be right???) All pictures that wer...

black & white with Pentax *istD
Short answer: no. Long answer: you can get fabulous results if you shoot in RAW mode, process on the PC (Pentax's plugin will do, but Photoshop CS is best IMO), then do the following (which works in Photoshop Elements too ;) ): 1. Add a Hue/Saturation layer and set the layer mode to "Color". L...

black & white with Pentax *istD
If you take your picture in RGB then you retain the possibility of applying filter effects that simulate coloured filters on b/w. Most of my b/w digital images start as RGB files. In the Epson printer driver there is an option to PhotoEnhance, one of which is sepia. This is a fantastically easy w...

Internet galleries
Mark, The Pentax User gallery is for images that were submitted for inclusion in the magazine. You don't always even get into the gallery! I submitted three shots and Peter Bargh didn't pick any of them :( I have used PBase and ePhotozine (www.ephotozine.com). Both are very good. However, PBa...

Digital Stabilizer on optio MX ?
Hi does the optio MX have a digital stabilizer (i know it doesn't have optical stabilizer) but to enhance mpeg 4 compression, i think if pentax can add digital stabilization in the next firmware, quality should be better. i have tried to stabilize 10 x zoom movie with virtual dub and deshak...

camera / shatter shake
Greg, I think you might be asking a couple of questions at once! To get the smooth water look on a waterfall, you need to slow the shutter speed right down. To get a correct exposure, the aperture will have to go a corresponding amount smaller (ie larger number). Here's the easiest way on the...

More sensor cleaning - beware the blower!
Hi Guys just a note to tell you of the woes I've had this week with my *iSTD and how I solved the problem. One of the first things I bought following the purchase of my new camera was a new blower which i bought from Jessops - a model called the 'Hurricane' - it looked suitably big and powerful. I ...

Post processing in Photoshop
Found a great suite of Photoshop filters for the digital photographer. Checkout www.digitalfilmtools.com/index.htm, they have filter packages for both Photoshop and Elements, you can download the demos and give them a tryout ,but there not cheap.
