Neutral Density Filter Colour Cast
Can anyone point us interested in these as to where we can get some good ND filters without breaking the bank? I'd greatly appreciate it! :)

none of the good ones are cheap, and if they're anything like my cokin filters, they're pretty easy to scratch, too :( Bret

Neutral Density Filter Colour Cast
Hi, I've recently bought the new version Hitech 10 stop, and yes they have cured the magenta cast. They've replaced it with a blue cast instead !

Neutral Density Filter Colour Cast
Wow, that's even worse than stacking cheap cokin lenses. What brand were these so I know what to avoid?! Nothing you could have done about it. Lee, B&W or Singh-Ray produce the finest filters, but they're all extremely expensive, and with Lee there's a massive waiting list.

Neutral Density Filter Colour Cast
I read something about this, after having some trouble with Cokin filters when stacked. It seems that some ND filters block visible light but not infrared, so the balance between visible and IR light is thrown out of whack, leading to a magenta cast. You can set a custom WB to compensate for it, or ...

Looks like there isnt a way of getting hold of good quality filters without spending a fortune- from the Lee website it appears they are struggling to meet demand and this has been the case for a while. The results from welding glass are better than these and very cheap.

Neutral Density Filter Colour Cast
I recently bought a Hoya ND400 that has an ever so slight cast. In the past I did some playing around with two linear polarizers and got a cast similar to the op's but more blueish (which can be interesting nonetheless). Prieni

Neutral Density Filter Colour Cast
From the information i've gathered together ,ND filters do seem to create a colour cast regardless of quality (i stand to be corrected on this) which i gather can easily be sorted in PP as long as you shoot RAW . I used a 49mm B+W 10 stop ND and it produces CC on long exposures .

Adobe photoshop CS5 Lens Profiles
Okay, cmaera raw is now working. At the top of the screen, as you stated, it says Pentax K20D and I can then select my lens. But still, when you then open the image in CS5 and select filter/lens correction, there is three drop down menus. First to select camera make, Pentax is there so no probs. Sec...

Adobe photoshop CS5 Lens Profiles
Steve, again thanks. I have the adobe generated profile for my tamron lens, unfortunately there are no profiles for my 18-55WR, 50-200DAL or 100 DFA macro yet so I will have to use a third party or as you say, make my own. I understand that most profiles are made for raw and camera raw is now behavi...

I do more sharpening with my K-5 than I did with the K10D. Have you checked the lens using the focus adjustment? I was wondering about this as well, I've only recently noticed I do much more sharpening with my K5 than with my K20D, and the K5 seems to be able to take much more sharpening as well ...

K5 sensor overheating/on way out?
Finally did some long exposures with the K5 and ND110 to see if I can jettison the trusty old K10. To my dismay most of the shots had these purple-tinged streaks on them. I was using live view and electronic level only to compose, then switching LV off. Full exif in images. Portrait orientat...

K5 sensor overheating/on way out?
Any chance it's something to do with interaction between the filters? Coking filters are known to cause purple colour casts. The marks look like smears; I would have expected sensor issues to manifest themselves as dead straight lines? Cheers John, I'd seen the Sony heating issues but that seems to...

K5 sensor overheating/on way out?
It looks more like reflections from a filter than sensor problems. Try a night shot without filter to see if the problem arises again.

K5 sensor overheating/on way out?
I can't believe the IR remote would have anything to do with it, but.. Don't take this the wrong way, but if this indeed proves to be a camera fault I hope this it's peculiar to your K5 and not indicative of another K5 ice-berg! I'd like to go along with Yves suggestion, but the marks seem too...

It looks more like reflections from a filter than sensor problems. Try a night shot without filter to see if the problem arises again. Yves, I cleaned the B+W ND110 and used a different ND grad between shots, in addition to changing location, lighting direction, sensor orientation etc. Reflections...
