ND gradient filters
I was just thinking the same thing. I've got the trusty uv filter which infact will effect this. I am going to try and file down the edges of the P holder as you have done to see if this makes any difference, otherwise i'll bite the bullet and go for the z pro. I am not one to leave the lens naked w...

ND gradient filters
I tried filing off the edges too and the vigetting is still there with the UV filter present. I will definently have to get the z pro. I think what some people don't understand is that, of course you can use p series filters with a wide angel but when you have a 77mm lense you can't. it is way to la...

ND gradient filters
Hi Simon, I use the P series with a wide angle holder, this only just manages to take the 12-24mm at full wide angle and you can not use a filter on the front to achieve this. So the P series is definitely a no go for you. The p series goes up to 82mm thread whereas the z series accommodates ...

Blue tint from a polarizer
At 300mm this is an extremely long lens and inevitably, even stopped down, the DOF is wafer thin so focus has to be extremely accurate and the camera should be on a tripod. I think aerial haze is apparent in your picture and a UV or skylight filter might have been more useful than a PL which is goin...

Blue tint from a polarizer
Thanks gartmorem, the irony is I took my UV filter off in preferance to my polorizer. :D Regarding the tripod, I took a series of experimental shots with my camera mounted. They were all set too manual focus, 250mm, iso 100, shake reduction off and every f stop the lighting conditions allowed. The ...

Bag buying advice
I keep getting very tempted by the look of the national geographic bags, but need to see one "in the flesh" as I suspect they might be very slow to undo and do up again. I Have one of the backpacks (the small, though there is little discernable difference between this and the medium) No worries wit...

Interesting BW conversion technique
The subtle differences are: a) Used the method in the mentioned link from step 1 - 9 b) used the same steps 1 - 9 but before starting did as PEANO suggests and set the bk & we points in a curve adjustment layer. Plus, added a gradient filter to beef up the blank sky which JR referred to as b...

Interesting BW conversion technique
Thanks for all the comments on the technique. Lilly, hope you dont mind but here is a version of your coastal walk done using CS4, NIK Silver Efex Pro and Paint with light action to improve the darks/highlights. In Silver Efex pro I chose Orange filter high contrast option

Are you PENTAX MAN ?
Peter, Just to confirm my sentance. The first photographic safari I went on in Kenya, I never used the hood as I didn't know what it was mean't for. When I asked someone, they said it reduced glare and that it was personal preferance. So I hapy continued without it :roll: Where do I have to leave...

Are you PENTAX MAN ?
maybe I'm just not very picky but I've only very rarely been able to get noticeable flare or contrast loss out of an SMC lens unless it has a filter on. Even when it does happen a hand is much more portable than a lens hood IMO. I use the hood on my Tamron 300 and there it certainly makes a diffe...

Recommendations wanted
Helicon Filter is also worth a look. My main RAW converter is Capture One and it is optimised for PEF files.

Hdr settings on K20 or GX20
I have just realised you are talking about HDR, not bracketing. As far as I can see, the camera produces HDR images from ONE original, not three (or five). I presume it does this by creating three separate images from one, with varying degrees of exposure compensation, then merges them to crea...

CPL Filters on a 10 - 20mm Sigma
Hi Andy, I'm sure it's because it's such a wide angle at 10mm, 110 degrees I think, that the filter will only work best when used at 90 degrees to the sun. :? So if use take a wide shot, some of the sky may be nice ploarised blue and the rest will be 'normal'. Very laymans terms I know... an ...

CPL Filters on a 10 - 20mm Sigma
That's what I had read as well so I think i'll just go for a UV filter to protect it. Many thanks, Andy8)

B & W Filter
Hi - hope someone can identify what this is - came attached to a second hand lens I picked up a while back. On the inside, after size, "KR-3 1.2x MCR" On the outside, "F-PRO" It has a "warm" tint. Tried the B & W web site, but no luck. Steve

B & W Filter
A KR filter IIRC is a warming filter. The KR1.5 is a skylight, so you have something like an 81A there. 1.2x may be the exposure factor. MCR will be the coating info. F-Pro will be the series of filters from B&W that this one belongs to.

B & W Filter
Thanks John - checked against my 81As and it seems darker - so may be a B. Steve

B & W Filter
I've found a B&W catalogue, so I can be a bit more specific now. MRC = multicoating F-Pro = Standard filter mount, suitable for lenses as wide as 28mm or possibly some at 24mm. KR3 = warming conversion filter. They have now started using the 81 series labelling, but they do give KR1.5 as being ...

B & W Filter
Many thanks John for the further info. It's not a very thin filter, even though its a 58mm, so probably won't be rushing to test it on my FA 20-35. Got enough examples of vignetting from misuse of filters to make me a bit more careful as to what goes on what lens. :oops: Steve
