Waterfall problem
The essential thing is to use a slow shutter speed, and that means using a tripod to keep the camera steady. For water shots, you may need to put a neutral density filter on the lens because the slow shutter speed will lead to over-exposure unless it is a very gloomy day. The great thing about...

Need help from a newbi pentax owner
As it's usual to stop down when shooting macro to fairly small apertures the quality from close up lenses (which just screw into the filter thread on the front of the lens) should be very good indeed. If you become totally enthralled by macro then you can always buy a dedicated macro lens later w...

Need help from a newbi pentax owner
Hi there John I am new to PentaxUser Forum and have recently purchased a K10D (my first DSLR) together with a Tamron 18-250mm F3.5-6.3 DiII LD lens, which I understand has a macro ratio of approx 1:4 I've never really experimented with macro photography before, but those stunning pin-sharp clos...

Would you call me a Luddite for suggesting breathing on the lens to create a mist effect and stretching a stocking/tights over the lens to give a softened effect. Fine suggestion ;) Don't forget that there's a marked difference between black and white 'nets' over the lens. Best bet to try this...

Best bet to try this out is to get a second hand UV filter and experiment. Vaseline can be used as well ;) Matt Cokin square filters can be good for this as well as there is no thread to have to try and clean it out of afterwards.

Long exposure using crossed polarizers [img]
After my last try in the evening that didn't yield satisfying results I went out to the shore again this weekend. Instead of waiting for the light to fade I used my old Kiron 70-210 for which I have a polarizer (52 mm, not fitting on the newer lenses). Together with the polarizer for the filter hold...

Long exposure using crossed polarizers [img]
.......... I have a polarizer (52 mm, not fitting on the newer lenses). Don't forget the crop factor. You can use a step-down filter from a 55mm- and perhaps even a 58mm-filter lens and not get vignetting. My 49mm-filter ring flash works fine using a step-down ring on my 58mm-filter macro lens. ...

newbie filter question
Hi Guys. Just got a K10 after a break of 20 years from SLR slinging. WOW! do I like digital! Quick question:- I always used to have a filter perminantly attached basically to potect the lens from physical damage. I assume this is still a good idea, what type of filter should I use on the DSLR?...

Gosh, I did not realise what a can of worms I was opening! Thanks for the link, it's no filter for me. :D [/img]

K10D Battery grip
Multi-exposure in camera is so slow that it can be rather useless. You don't keep the 3fps shooting speed which you really need to combine a lot of sequences. Fair point. There's a fair bit of processing to do though, I guess, especially if you have auto EV on, so I suppose it's not surprising. ...

IQ fix in K10D Firmware update?
They don't mention whether they were using SR enabled with a tripod when doing the tests - it's possible that had a bearing on the matter. I have never had a problem with image quality on any of the Pentax cameras when using Capture One and Silkypix. Other converters have image quality problems I...

IQ fix in K10D Firmware update?
... When I had a close look at it, I think there may be an example of the sort of artifact you're refering to. Here it is, the highlight at the toe of the shoe. Dan Thanks Dan. It is very hard to see, but there may be a couple of 'phantom pixels' sparking off the end of that shoe. In that context...

Now it so happens that for my sins I'm a typography buff so I was especially disappointed in the results with the labels and batteries on the DPReview site, and confirmed by this image here: http://www.photozone.de/8Reviews/dslr/pentax_k10d/iso/iso100_acr37.jpg (large file).

IQ fix in K10D Firmware update?
Erm, you want tack sharpness, which film doesn't have for a start. Complain about the AA filter when this is completely bypassed when shooting RAW and you can get exactly the image you want. A good RAW workflow tool like Silkypix or Lightroom is worth spending on (never tried the included Pentax one...

Flash Sync Speed
I know there is a hi speed mode on the 360 and 540 flash units but is this possible to do with other units so I can use them off flash? Yes, it's on those guns. No, you cannot do it on any other flash. It's not just a "pin thing", it's a physical impossibility. It works like this, and i...

Flash Sync Speed
Matt, I was hoping you'd spot that post! Thanks for the explanation on that and it looks like I'll have to bite the bullet and buy a modern flash unit although I love my Pentax 240 flash. I did spot that the 360 is out there for 135 quid now. I did think about the ND filter and dropping to...

Flash Sync Speed
Rob, Just to mention - you only get "HS" mode when the flash is tethered. You can't do wireless HS mode (just so you know!) I meant put an ND filter on the lens! You need to ignore the flash (for a minute at least) and bring the ambient light down to a manageable amount. If you can't g...
