circular polarizer multi-coated glass or not?
That would still mean four reflective surfaces in front of your lens. Besides, the CPL filter needs to be rotated to achieve maximum effect. This is difficult if you want to have an ND grad filter in addition, which also needs a specific orientation (i.e. vertically). I think you will reach your ...

Cokin P filters.
Hi all, I have just started using filters, and my question is that I read that p filters are square when clearly they are rectangular. My first filter is a P.121F. Advice would be welcome Regards Chris

Best way to take photos from a plane?
Cessna single-engine aircraft are all high-wing, which is good for photography. If you are taking pictures through the window, then the hood will not be that good for eliminating reflections, unless it's rubber and you press it against the window (in which case as Chris said, vibration will be a pro...

Filter for underwater photography - worth it or not?
I'm planning to try some more underwater photography, and am considering buying a proper blue water filter (basically a good red filter). I'll be shooting RAW so I was wondering if it's actually going to make any difference? Basically, am I going to get exactly the same effect from adding a red filt...

Filter for underwater photography - worth it or not?
You will get the same tonal effects in post production, but not the same effects where you are enabling youself to see past haze, or polarise the light, or indeed punch through the murkiness of water. So there are still some circumstances where a filter is helpful, and you may well have found one...

Filter for underwater photography - worth it or not?
I hadn't even thought of using the polariser. Might have to be a bit hit and miss - the polariser I have is circular so I'll have to set it before sealing the case. I'm using a Ewa Marine case (well, bag really) so opening and closing near the water isn't that practical...

Filter for underwater photography - worth it or not?
It was just an example of the sort of effect that can't be replicated by post production, but whether or not it's applicable to your situation I don't know.

Filter for underwater photography - worth it or not?
I think the polariser will be too hard to operate underwater and you'll lose too much light depending on the weather and water conditions. If the purpose of the filter is to colour balance (sounds like a film filter) then you would are right to shoot RAW and sort it out later, I have a proper de...

Filter for underwater photography - worth it or not?
I'll definately give the polariser a go - it'll be in the Indian Ocean so hopefully light won't be a problem, and I won't be that deep. I'm interested to see what effect (if any) the polarisor would have on refraction in the first 10 metres.... I can just about look through the viewfinder with m...

Photoshop alternatives
Pixelmator is nice... For graphics. It struggled a bit on large photos for me though. The feature set is nice, but not 'up there' for me yet ;-) I'd definitely recommend PSE with some of the free/cheap scripting addons that expose more of the PS features. I consistently find PS & PSE the fastest ...

Unusual photo op - explosion.
An addition/alternative to Flossie's suggestion is the long exposure with a flash (less ambient light). You'll see the equipment and any spark arcs. But you can get longer exposures. I've done a fair but of painting with light using led torches (read sparks). If the camera will do continuous 3-5...

Distortion Correction (Keystoning?)
Thanks all. I had a closer look in the GIMP and there's a built-in filter for lens distortion to fix the curvy lines, so I tried that. Then after a bit of Googling, I found that the "perspective tool" can be used to adjust the leaning. This is a first attempt, and not quite there but I think I'm on ...

Is there still a place for filters In a digital world?
Any type of colour filter can be replicated with software. Of course infrared photography and other special kinds along this line not included.

Is there still a place for filters In a digital world?
My most used filters on digital are R72 (infrared) and polariser, followed by ND grads. The first two are hard to replicate in post processing (Virtual Photographer tries to do a polariser effect which can be quite effective with colour saturation, but cannot control reflections in the way that o...

Is there still a place for filters In a digital world?
Well well,thats interesting, not much of a response, from which I infer there is not general usage of filters any more,I am surprised. Alistair Most of the time filters were used as white balance correction filter or like Hefty says for B&W but those are of no use any more since that can all be don...

Is there still a place for filters In a digital world?
I seem to have a need to try various things so have acquired lots of stuff that actually I very rarely use :D. My filter collection is amongst this pile. I have a circular polariser but hardly ever use it. I have recently bought a ND grad with a vague idea that it might improve my landscapes but ...

Is there still a place for filters In a digital world?
I'd like to try UV photography but the UV passing filters start ~£200 which is too much for me, especially as I might find even my older lenses block to much UV. There is also a filter in front of the sensor that blocks UV so that's great the ones in the k10D and newer models also blocks infra-red ...

Is there still a place for filters In a digital world?
Where is the option "none of the above"? The only filters I use, or plan to use, are the polafilter (which I have) and the ND grad filter (which I plan to get). Everything else I think is just as well done in Photoshop.

Lenses & spectacle cleaning
These days, I try to avoid cleaning lenses unless absolutely necessary. When I have to, a product I have found to work well with filters and lenses is 'Calocoat' which can be used with 'Calocloth' or any other high quality microfibre cloth. I always spray a little onto the cloth and not directly ont...

J.Peg or Raw
Personally I use JPG, as I'm quite happy with the results the camera produces in that format and I'm not sure RAW would help much with my usual problem of blown skies (a grad ND filter would be much better). I do wonder if the JPG processing engine on newer bodies has improved, as pretty much eve...
