Guides on color grading, LUT workflows, and getting cinematic results.
color.io went offline on 31 december 2025 and apple later bought the company. what happened, what pro users kept, and the film emulation tools that replace it.
copy a lut into the right folder once and it stays in the menu. exact folder paths for premiere pro, davinci resolve and final cut pro, on mac and windows.
a lut (look-up table) is a file that remaps the colours in an image. what lut means, how luts work, 1d vs 3d, .cube files, and how to use one in your editor.
open several photos in luttie, build one grade and switch between them to check it on each. three photos on a free account, twelve with pro.
ai-generated clips arrive with a look already baked in, and it changes from one generation to the next. how to even them out and give them one grade.
image-to-video keeps the colour of the photo you give it. grade your stills with one look first and every clip comes out matching.
most browser video editors can't import a .cube lut. which ones can, what we couldn't confirm, and how to get the look onto your video either way.
film grain is the random texture of film, made by the silver and dye that form the image. what causes it, why movies still add it, and how to add it.
luttie's film engine now decodes apple log 2 from the iphone 17 pro: same log curve as apple log, apple's wider gamut. what changed, and how to use it.
the real dehancer alternatives, free and paid: spektrafilm, filmconvert, filmbox, emul8 and luttie. current prices, what each does, and which to pick.
printer lights are how film labs balanced a print, in points. what a point is, why 12 points is a stop but a stop of exposure is 6–8, and how to use them.
film print emulation imitates printing the negative for projection. what it does to an image, why colourists use it, and how to add it without wrecking the grade.
the histogram is the one scope that tells you the truth about exposure. how to read it, where to put your blacks and whites, and what clipping actually costs you.
some grading steps give the same result whichever order you run them in. others change completely. here is which is which, and why it matters for your grade.
turn on advanced mode, open the node graph, and drag a stage earlier or later. how reordering works, what bypass does, and what carries through to export.
luttie's grading engine is rebuilt: ten reorderable stages, a node graph, per-stage previews and 16-bit float processing. the simple editor is unchanged.
nodes let you see your grade as a chain of separate steps you can reorder, switch off and inspect. here is what that means and why colourists work that way.
a .cube lut maps colour to colour and knows nothing about where a pixel sits in the frame. that is why vignettes and grain can never be baked into one.
luttie's grading engine has always been a single fixed chain of adjustments. i'm rebuilding it into something you can rearrange, branch, and mask — and that changes what luttie is.
most browser-based video tools upload your footage to a server first. here's how local, in-browser grading works, how to verify a tool isn't uploading, and where the limits are.

a .3dl file is a 3d lut: a colour lookup table used by autodesk flame, lustre and avid. how it differs from .cube, which apps open it, and how to export one.
