Hi Guys

I had my first go with some ND filters today but they didn't come out like I wanted.

They all seemed to turn redish

I used a ND8 filter & tried different shutter times up to 3 secs but all seemed to come out the same, why different shades of red:shrug:


Any advice on this problem peeps as I'm lost

(Not all photos were taken with the sun in shot but still came out the same:thumbs:)

what make filter was it?
 
DHD are just coloured filters they aren't ND.

they say 52mm ND8 on the case & the filter ring

I'm confused now

I've just looked on the side on the filter & it's marked NEEWER ND 8

just had a look on ebay and it does say ND8, some of the cheaper ones do give a colour cast, i have a hi tech pro stopper that i have to adjust the WB of in post, i would suspect that this will be the same, the best cheaper screw in i had was a b & W
 
Rest assured they aren't ND!

Thanks, How can I tell before trying them that they are ND filters?

Buy acknowledged screw-in makes such as Hoya or B&W - or square type like Hitech, Cokin, Kood or Lee but they will cost considerably more ... because they actually are ND filters rather than cheap coloured glass.

Reputable manufacturers who state that their ND filters are neutral density ARE neutral density filters. You will inevitably get some colour cast but not as extreme as these ebay cheapies.
 
Looking at it again, it reminds me of the opening or closing shot from Knight Rider... Sorry not helpful or relevant...
 
OK Thanks guys, buy cheap buy twice eh?
lol

It does look like Knight Rider ;-)
 
I originally bought neewer stuff, most of it is in the bin now, the ND filters all threw a massive magenta colour cast.

As I have a very limited budget I tried the sevendayshop branded ND and they work really well, the ND8 being the only one that leaves a slight greenish cast which is easily corrected using a white balance reference taken with the camera using a grey reference card( again 7dayshop )
 
I have just invested into some ND fliters. I decided to not go for the screw in ones instead I bought an adapter from cokin, (amazon sell it) it allows you to buy there square filters (much much cheaper for a better product) and you only need to buy an adapter for each of your lenses to be able to use all your filters.

It isnt really really cheap but been able to use them on every lens is a massive pro point. I spent just over a hundred pounds and got N2 ND4 ND8 and Grad versions of all three as well. along with adapters for 77mm and 72mm.

Go have a look i think its worth the time. :)
 
According to the exif in the image you have the white balance on manual and set to "fine weather". If there is a colour cast, then a manual white balance that hasn't been taken with the filter on is not the way to go - either do a custom manual on on a bit of white or grey card, or set the white balance to auto and see what the camera can do!

:lol: :lol: :lol:

I also bought some cheaper ones, but that was while i was waiting for my 3 month order for Lee Filters. After the first try with them, they went straight in the bin. Always go for the best you can afford and a little more :thumbs:

Well worth the wait :D
 
Okay I know i was raving about how good the cokin set is that i just ordered.
However i decided i would like a higher ND of around 64-400 so that i can expose for over a few seconds in a very bright day.

I have just found that there are virtually no ND filters for cokin above ND16. (plus i found out on long exposures they light leak very slightly)

Does anyone know where i can find some? Or a cheap ish ND screw on for 77mm.

Would Nd16 be able to get me to an 1 second exposure on a fairly sunny day at f/22?

Edit-- Will make a new thread since i really need some advice :)

Using a Neutral Density filter - especially 6stops or more, will usually result in a warm cast - but certainly not to the extent of the OP's image.

Due to the time the sensor is subject to the light, Infra Red that is not visible to the human eye will effect the image. Yes there are IR filters on the sensor, but they vary in effectiveness - so you can either post process the cast out or add an additional IR blocking filter.

Filters like the Lee Big Stopper aren't ND, it is described as a long exposure filter and they appear to have tried to design it to counter the IR and produce cooler results.

From what i've heard the new B+W multi coated 6 and 10 stop ND filters seem to produce good results and some of the variable ones are OK up to 4-5stops.

It depends on the quality of the filter. I had a no-name cheap ND that gave somewhat similar results to those the OP is getting.

Luckily it was fixable in LR.
