UV filters on Digital *istDs
I totally agree with George - don't fit filters anless you need them photographically. I know the arguments about protecting the lens are there, but how often have you damaged a filter? Never? Then that's how often, hopefully, you will damage a lens. I think a lens hood is far more essential -...

Am I the only one searching for real UV filter to use when I want to cut on distant "haze"? Does it really make a big difference? I live in a beautiful mountainous zone where the mountain peaks far away are almost always very "foggy"... I have the Cokin A series and will buy their UV (as soon as...

If you have distance haze then a filter may well be necessary. Personally, I have never found the UV filter to be enough, preferring the Skylight or even an 81A with colour film. For black and white film then a red filter is the most effective, or the Infra-red one even more so if you are after spec...

I know the arguments about protecting the lens are there, but how often have you damaged a filter? Never? [quote:62a74e0893] I am wary - from personal experience some 23 years ago when the camera strap broke! My old Fujica ST701 with Tamron 80-210 fitted swung rapidly from my shoulder to hit ston...

Your tale about the camera strap breaking reminds me of a mishap I had. I was changing a lens while walking down a street in Milan and dropped a Pentax 120 lens. I tried to get my foot under it to break its fall but this resulted in me kicking the lens down the street. The only damage was a small ch...

A similar, and recent, story from me... I have Hoya Pro 1 filters on my main lenses (99.7% light transmission). While on holiday in the west of Ireland last week, my SMC-FA 24-90mm was on a film body, in a case and got knocked off a seat while on a boat (my 18 month son's legs were flaying rather w...

A few years back I dropped my camera off a mountain. It landed lens down. Fortunately I'd been using a cir-pol filter at the time, which took the brunt of the impact. Ever since I've had two rules: 1) Keep the camera strap around your neck at all times, no matter how tempting the shot. 2) Alwa...

I make my comments from the perspective of a film camera user, as I'm still waiting for the right digital camera (Pentax, of course) I leave a filter on all my lenses (generally a skylight), which means that when handling the lenses, if I get finger marks on the front, then I only have to clean t...

UV filters on Digital *istDs
This is one of the original religious wars in photography. This question has been argued as far back as I can remember (the 1950's). My personal experience is that: 1 - I don't notice any difference if I use a well-maintained quality filter on the camera, and 2 - Keeping the filter clean ...

The only lens that I 'damaged' was my F35-135, whilst fitted to my SFX. It fell off a seat in Malaga airport, it was inside a padded holster case with filter and lens cap fitted. Despite the padding and the fact that it only fell 18" or so, the lens barrel became loose. At first, everything seemed ...

Hi, I have to put my hand up to being in the camp that uses filters most of the time. However, I do make sure that they are good quality. Over 25 years or so, I have managed to dent the thread in 5 filters which, bearing in mind most of my lenses are the older metal bodied ones, would have meant de...

Sensor Cleaning
Hi Trevor, You will find the sensor needs cleaning when you have black specks/ small splodges on the pictures that aren't there in the original scene! Taking a photo of a plain sky will show up the dust (I have found whether its blue or cloudy!). If you see only one, maybe 2 spots, it's probably ...

Sensor Cleaning
The SensorSwab/ Eclipse fluid approach works really well - just takes a couple of goes to get the knack of not leaving streaks behind! Just a word of advice about using compressed air - if you are tempted. The thing you are cleaning is actually a chromatic filter mounted above the sensor, so hig...

? about sharpness
Just a litttle aside about sharpening in Photoshop: Sharpening is the last thing that should be done, if you use the Unsharp Mask. But there's a trick that adds a little sharpness non-destructively. Create a duplicate layer of your background. Use Filter>Other>High Pass. Move the slid...

Pentax ist ds - raw vs jpeg
The masses tend to follow the crowd without much thought. Canon and nikon dominate the advertising arenas and therefore get all the advertising media sponsored press. I rember one group of photogs I took to shoot Arctic wolves in Great Slave Lake. I rember one fella in particular, who burned throu...

Pentax ist ds - raw vs jpeg
MattMatic said "You'll need to give it time - RAW processing takes a little skill and practise, just like hand developing! Matt" I say wait for Pentax to come out with the *ist ds4 featuring the "MattMatic" filter for extracting the sharpest Jpegs possible IN CAMERA!

Pentax ist ds - raw vs jpeg
I'm glad you laughed and want to make people fully aware it was intended as a compliment...really, the noise filter in these cameras started out as some ingenius guys' technique, that became a plug in, for some version of photoshop, that camera makers studied to devise algorithyms for my ist ds2. I...

Filters, Keep or Sell
You can do most things in post-processing, and that's what I do. The exceptions are the use of polarizers (which you have already mentioned), the use maybe of an IR filter and perhaps any filter intended to reduce haze and light scatter. Filters do sell quite well on eBay, so that's not a bad ...

Switch over to ist
I hate to dissagree with George, but digital black and white is incredible. You can achieve effects and techniques in computer, that were time/labour/skill intensive and even impossible in the darkroom, with simple tools like pse. You don't get channels with elements but you can use two hue/saturati...
