    GH5 to Alexa Conversion

    I’ve still been playing around with the X-T3 and Emotive Color using a CST in Resolve. Results are pretty good, but it just makes me even more excited for eventual native F-Log support.

     

     

    Can you add some more details about your workflow? I now have an X-T3 and would love to have even just an approximation of emotive color (I already own it for GH5 but sold that camera).

    I used Tiffen black pro mist in the past, but more and more often im opting for using diffusion in post production. Except for some very minor thing i found no difference in using diffusion in post, and you got  the advantage of adjusting it shot by shot.

    This was a very tight production, and time was short. So I decided to shot very clean and then finish in post. Although the vintage Pentax glass has some very particular look. 

    What's your post diffusion workflow if you don't mind me asking?

    Its a combo of compressed contrast because of higher halation than the Alexa (distinctly higher with LC1/4), and a missing top three stops.  DD1 with light Olpf settings (5.2/20) is quite a close match (optical Olpf side-by-side coming)

    I shoot to 1080p, as that's all I need (a match to the classic); if you don't mind the data rates, 4K is worthwhile (most are shooting to 3.2k with Alexa Minis today, and some high end productions to Alexa 65/LF)

    Thanks! I'm going to buy GHa in a moment, even though I don't have a GH5 yet :) Hopefully I can find some sample footage to practice on (perhaps even some G85 Cinelike D just for the fun of it!). 

    I was thinking of getting two filters - one variable ND for convenience and a Black Pro-Mist. But I gather that getting a DD1 would be a better choice?

    Yes, that's why I didn't even consider filters for so long. Its not specific to Firecrest, those are the reference Full Spectum NDs for EC though (how the Day conversion was made). It needs a minimum of a 2 stop ND to fully cancel out the reflection; the glass also needs to be parallel to the sensor plane, as one ND I have is slightly off axis, resulting in a diverging reflection.

    Interestingly, the Alexa doesn't even have this problem, despite having CMOS, as best I can tell. The falloff is silk and there are no ghost reflections, as I believe the filter is 'integrated', and not a stack (that causes 'stair-stepping' falloff):

    I'm looking at those shots on a crappy old laptop, so take this with a grain of salt - but while the GH5 with filters shot looks great in terms of fall-off, it also looks quite soft. Won't all this manipulation make the image too soft (LC, DD1, digital olpf, 1080 upscale)?

    I like a detailed, organic filmic image. Not the overly sharp digital look. But I don't want to go too far in the other direction and make it look like it was shot on Betamax with a 35mm adapter :)

    Sage, this is bloody amazing. I've read the whole thread now and watched just about every video posted. I didn't really consider the GH5 (small sensor etc.), but with these settings, it blows everything in its price range away. Sony colors look mighty wonky compared to this. If I get a GH5 this is an insta-buy.
