For Fujifilm X100 and Ricoh GR JPEG-first photographers

Keep the color science. Add the headroom.

ToneLatch pairs the JPEG you already love with its matching RAW to create real Ultra HDR. The JPEG stays the picture; the RAW only adds highlight headroom.

Your camera already made the look.

ToneLatch is designed around Fujifilm X100 series and Ricoh GR series matched RAW+JPEG pairs. It preserves the beautiful rendering you chose in camera while adding brighter highlight intensity on compatible displays—without asking you to regrade the photograph.

Keep the camera look

Your film simulation, recipe, image control, or grade stays in charge of the final rendering. ToneLatch does not rebuild the picture from RAW.

Add real HDR light

The output is a true Ultra HDR JPEG with an SDR fallback, not an SDR tone-mapped image dressed up as HDR.

Stay in a simple workflow

ToneLatch is designed for Fujifilm X100 and Ricoh GR RAW+JPEG shooters who want minimum post-processing.

Quick proof

Three scenes. One simple idea.

Compare the brightest windows, reflections, and sunlit surfaces—not saturation or contrast. The film simulation or JPEG grade remains visible in both versions.

Compatibility

Designed first for fixed-lens compact workflows.

Fujifilm X100 series and Ricoh GR series files are the primary support target. Other camera systems may work, but are not officially supported because lens correction can produce alignment differences between a JPEG and its RAW. Try ToneLatch Basic on your own files before buying Plus.

HDR rendering also depends on the viewer, operating system, device, and display. Unsupported viewers show the conventional SDR JPEG embedded in every Ultra HDR export.

Next step

Give your JPEG the light it was missing.

ToneLatch Basic is free, processes your photos locally, and creates both Ultra HDR and Native HDR exports. Your source files are never overwritten.
