Thread: Field Test with Formatt Pro ND10

    Default Field Test with Formatt Hitech Pro ND10

    1. This is a field test with Formatt Hitech Pro ND10 Filter.
    This field test will be focusing on the colour cast this filter produced and how easily it can be corrected. This filter comes in 2 version, 85mmx85mm (Cokin P) and 100mmx100mm. I am reviewing the former version.

    As you would have know, this filter comes with a gasket to prevent light leakage but it cause severe vignetting. thus, i have removed the gasket and DIY my own gasket to seal a gap using a soft foam material from daiso, cut into size, double side tape it onto the holder instead of the filter. The Result turned out pretty well.

    2. Disclaimer
    This test is not done is a controlled environment and has no scientific backing. It is based on my own opinion and experience.

    Thank you Administrators and Moderators for approving my half cooked review. I shall continue with the rest.

    5. Maintenance
    This filter is rather easy to maintain. Blower, spectacle cloth and lenspen for stubborn stain.

    6. Feedback
    The colour cast seems strong, but it is reasonably easy to correct. The severity of the colour cast also differs under
    different lighting conditions. I still prefer my old B+W ND110 in this aspect though. Having said that, the blue cast
    seems to make the sky and water more blueish, which can be a nice thing.

    This is certainly better than the old 10 stop. However the Blue cast is very severe, it's best to shoot in raw to color correct the image in a photo editing software. nice review

    Thanks for dropping by fellow Hitech Pro ND10 user.. Yes, the colour cast seems severe, but in-camera custom white balance or PP could easily correct it. Any shots to share?

    Yep As you can see there are still some Blue tint on, i just desaturate it to make it less obvious

    Before: ACR default treatment


    After:


    almost no blue cast once loaded in ACR. it can comfortably auto-compensate for the blue cast, though on-camera LCD it was very obvious.

    color information (RAW) is still satisfactorily captured and retained, though I haven't tested it extensively.

    Straight out from camera, its blueish alright but easily corrected if shooting raw.

    I think its the water drop cos i was taking at a low angle close to the water prior to shooting this.

    @chiangkxv: Thanks for a really useful review!

    I wonder if you could tell me how you removed the foam gasket, and any cleaning solution you used to remove the glue residue?

    Its not glue, its some double sided tape. So turpentine does a decent job.

    U will need to improvise your own gasket. A bad job will lead to light leak during long exposure.

    Btw, I got a bad copy (initial ver.). So back to using b+w nd already.

    Many thanks for the info. Thing is with my Cokin holder the existing gasket doesn't even form a decent seal, so there's no reason not get rid of it and make my own, but I guess I'd better check my filter thoroughly for defects before I take the plunge!

    Thanks again.
