Evening all having some trouble getting the correct tone back in my pics!

I'm new to 10 Stop filters and fairly new to Photoshop but basically I've had a brilliant day out up a waterfall today and I've came back with a few images I'm over the moon with and want to get them processed right!!

I took the same image with and with out the 10 stop and the 10 stop filter seems to have lost the original colour :( CAN I GET IT BACK???
 
Since nobody has answered. :thinking:

It depends on how much of a colour cast, and whether you shot in Jpeg or RAW.

If it needs a big change, and you shot as a Jpeg, then it is possible that any big change may degrade the image and not be possible to fix. Though you may be able to do it.

If it was shot as a RAW file, then any large change will degrade the final result less, if at all, but you may still not not be able to fix the image if it is a big change. Though you may be able to do it.

I know, a bit vague, but until you can show a normal image, and an image with the colour cast, and say what files format you captured the image in, it is a bit difficult to give advice on a way forward, or even if it is possible to fix.
 
Thanks for the help so far I'll get 2 unprocessed photos up soon once I get on the computer! Yes I'm shooting in RAW as I made the JPEG mistake a long time ago!

Thanks for the link I'll give that a try as well!!

I also started another post asking if any one else has used the same 10 stop filter and I got a reply who said they changed filters as the cast was to much for them!! So I may have to do the same if this takes to much processing
 
What make of filter is it?

Why are these filters giving colour casts? I've never used a 10 stop filter in my life, but I've used plenty of normal ND filters. They shouldn't be adding a colour cast. They're supposed to be neutral density filters... NEUTRAL :) So what happens if you use one of these stupidly expensive filters with film? What are you supposed to do then?

Any neutral density filter than adds a colour cast is sh1it.. it just shouldn't be doing that.


[edit]

You just posted the image as I was posting. That's terrible. Even at the RAW level, removing that will have an adverse effect, as the greens are seriously attenuated, and most likely you'll get increased noise after balancing.

One way you can correct this... and I'm surprised no one's mentioned this yet, is take a shot with a grey card in there as a reference. So effectively, take each shot twice: Once with a grey card, once without. White balance in post off the grey card, then just apply those settings to the one without the grey card.


I'm shocked at how crap these filters are though. The first thing I'd be doing with that filter, is placing it in the nearest litter bin.

[edit again]...

Juts to test it's the filter and nothing else.... take a test shot without the filter, but do not use auto WB. Set it manually as a colour temp, take a shot, then change nothing (except exposure of course) and take a second shot with the same manually set WB. If you still get this mahoosive red cast... then it's just a crap filter.

Thanks for the edited reply I think it's getting binned! Any way it's a Tiffen 3.0ND 10 Stop got great reviews on a couple sites!

Those 2 shots were exactly the same settings other than the exposure time but I'll try a shot of the clouds out the loft window soon with manual setting white balance!!

Might just be easier to bin the filter and get a different one
 
I;d check out others before you bin that. If the next one is so bad as well that could get expensive.

I just don't see the point in a ND filter than makes your images red though. Try the manually set WB as a final process of elimination before you do anything though.
 
I had a quick play and got it pretty close to your original (it didn't help that I had nothing to compare it too untill I finished) I ended up having to alter some of the colours as well as white balance, so it's not a one click fix, I suppose you could set up a preset in Lightroom or camera raw once you get it sorted properly the first time.
The big question is does it vary in different lighting condition? if so t'd be a PITA to make a lot of different presets.
 
As you have a shot from the same position - you could blend the layers in Photoshop.

Below is literally just a single document, auto align layers and then change the blending mode of the correct colour layer to 'colour', so all the brightness texture remains.

I'm sure you could improve on it further if needed.

any chance of seeing how close you got it? ive had a good play around this morning and got it sort of close but the greens are still miles out
 
Not sure of your editing software, but just a quick edit via PS CS5. Using the auto colour, works, you can then start to edit the image more from here. Most filters will have a colour cast whilst using long shutter speeds, LEE usually has a blue cast which is quickly rectified, its important to use RAW, this way you have more control on the editing.

From memory, but you get the basic idea.

1. Open both documents in Photoshop
2. In the document with the correct colour - select all the image (ctrl A), Copy it (ctrl C)
3. Go to the document with the ND image in it and paste the colour version in as a new layer (ctrl V)
4. In the layers palette change the blending mode from 'Normal' to 'Colour' on the correct colour layer
5. In the layers palette, select both layers and select 'Auto Align Layers' from the Edit menu

Takes about 30 sec in all to do all the steps.

thanks so much for your help im heading out now but will try this when I get home then upload the rest of the images for comments thanks again
 
Here you go, It's not quite there but you could get closer with a bit more time and care.
 
@bbg404 ben pm me your mobile number, I'll give you a call about this when im on my lunch.

Also, have a look >>> Here <<< as it shows you how to do custom white balance on a d5100 so will probably be similar or the same as yours. Set the custom white balance every time you use the 10 stopper and it'll be fine. just out of interest what thread size is the ND filter?

Next time just take white / grey card and use custom white balance if you struggle to adjust it in post.

In short cool it down and shift magenta / green slider to the green end. That should get you close, although the filters may not have linear effect on all colours so except small differences from the "reality"
 
Well even after some quick fixes and trying some custom white balances I've went and Ordered a Camdiox on a members recommendation cant wait for the weekend I've got from lunch time Friday till Sunday evening taking pics ..... the Mrs is away ;)

Unfortunately it seems quite common amongst some of the cheaper 10-stop NDs. That's why you'll see a lot of B&W conversions, it's often the only way to rescue anything. If you want to be really shocked try searching for those who swear by welding filters.
 
Welding glass.... (shudder). Great if you like green :)
