Hi All, I'm currently working on an update for LUTCalc, and have uploaded an online version to LUTCalc Testing. I've been playing with the picture profiles in an a7s mkII and had a go at analysing the Cinegamma 3 and Cinegamma 4 curves. I checked my process against the Cinegamma 1 and...

Hi All, I've just posted a major update to LUTCalc - v3.0. Quite a lot of work under the hood, and a few more visible developments. Probably most useful is the 'Gamut Limiter'. When you go from a wide gamut like S-Gamut3.cine to Rec709 the leftover colours can lead to nasty clipping. Gamut...

Hi All, after a pretty busy summer filming, I recently got back into looking at LUTCalc, in the past few weeks I have uploaded several updates. I realised that I hadn't mentioned any here, and since I usually write a post, I thought I'd bring things up to date. With v2.5 I added a 'Black...

Hi All, I've just uploaded a new version of LUTCalc to the lutcalc.net website, GitHub, the Mac OSX App Store and the Chrome Web Store: Run LUTCalc page * New Feature - Print out the Stop vs IRE chart, plus exposure table and IRE / 10-bit values for each stop from -8 to +8. * New Feature -...

Hi All, I've just uploaded some fairly substantial updates to LUTCalc to the online 'testing' version. Link here: LUTCalc Testing A couple of the new bits have needed some significant shuffling around under the hood, so I'm not quite ready to release it as an update and I'd really appreciate...

Hi All, this thread should really read 'The World's Most Expensive Lightmeter' - MLUT. The LUT's free, the camera to bung it in, the expensive bit! ;-) I recently bought myself a DJI Osmo, and one of it's options is to shoot what is listed as 'D-Log'. The thing is, I can't find any tangible...

Hi All, just to let you know I uploaded a new version of LUTCalc the other day. It is up online at lutcalc.net, and it should have come through as an update on the Mac App store and Chrome Web Store. The new stuff is: * New Feature - Hybrid-log gamma. * New Feature - All Sony Hypergammas...

Hi All, I took a bit of a break from geeking out over Christmas, but then decided to have a go at figuring out all the hypergammas for LUTCalc. I've added them all to the online testing version (LUTCalc Testing), plus recalculated Rec709(800%) with a reverse (to help if you accidentally bake it...

Hi All, I'm a lighting cameraman with a Sony camera and for some time I've had a hobby / obsession developing a tool to let me create MLUTs and grading LUTs for use with log shooting based on manufacturer-developed looks which I can then tweak. I usually post on the Sony F5/F55/FS7 forums but...

Hi All, I've just had v2.0 of LUTCalc accepted by the Mac App Store, plus a packaged version for Chrome on the Chrome Web Store. Links to the stores are on the LUTCalc home page, which has also had an overhaul with a bit more info: LUTCalc home page I have tweaked and updated a fair bit...

Hi All, I've just uploaded a new version of LUTCalc. I've been working the code of the colour temperature shift and fluori adjustments and have significantly overhauled things. I've also changed the preview window so that the LUT output options and 'Generate LUT' button stay visible - I've had...

Hi All, I've just uploaded a new version of LUTCalc (v1.9RC11). There is one big change under the hood which should barely be apparent to a user, and one of my annoying little (but important) bugs fixed. Links: LUTCalc main page (with web app version) LUTCalc For Mac releases page on...

Hi All, I've just uploaded a new version of LUTCalc and LUTCalc For Mac, and this one really, really should be the last before calling it v2.0. I'm planning to submit the LUTCalc For Mac version to the Mac App Store, so have added a bit more than I intended to make it more flexible / generally...

Hi All, after a couple of days of trying out every combination of adjustments I could think of (picking off a few bugs along the way), I've just uploaded a new build of LUTCalc: LUTCalc Main Page LUTCalc Github Releases Page LUTCalc For Mac Github Releases Page It's mostly bugfixes...
