Keep the source, the range, and the decisions visible.

Varve adds genuine sensor development and reviewed bracket merging to the existing Photo/Image Tuning surface. It keeps the original bytes and recipe available instead of turning a thumbnail into a claim of RAW support.

One editor, explicit stages

From sensor data to a considered image.

01SourceImmutable DNG or reviewed bracket

02Develop / mergeLinear working data and bounded alignment

03Review / exportSDR rendition plus range-bearing master

Available in the verified subset

Useful controls without invented camera support.

Classic uncompressed Bayer or monochrome DNG, with packed 8/10/12/14/16-bit sensor samples.
As-shot or custom white balance, camera-matrix or explicit sRGB fallback, exposure, black/white, highlights, shadows, crop, and orientation.
Reviewed bracket selection, reference frame, exposure entry, bounded translation alignment, conservative deghosting, and separate radiance/fusion semantics.
Float32 scene-linear computation, SDR preview, and single-part uncompressed OpenEXR float16/float32 master export.
Ultra HDR gain-map JPEG sharing: the stored SDR rendition becomes the base image and a separate per-channel recovery map carries the extended range, so an SDR viewer shows exactly the rendition you reviewed.
Reopen a supported range-bearing OpenEXR on an SDR-only runtime, adjust the SDR output transform, and keep the master unchanged.
Persistent clone, heal, spot-heal, and patch repairs on the existing raster-layer target, plus a linear-light dodge and burn brush with shadows/midtones/highlights focus.
Downstream pixel repairs are baked to the RAW source revision: changing white balance, exposure, or the profile afterwards keeps the repair bytes intact, shows a stale-repair warning, and requires an intentional reapply or rebase. Verified end to end in the browser, including save/reopen.

What this does not claim

This is not universal camera RAW support. Proprietary vendor containers (CR2, NEF, ARW, CR3, RAF, and friends) are detected and refused with a clear recovery route instead of a decode error or a silently promoted embedded preview. Conversion only works when it produces a classic, uncompressed 2x2 Bayer or monochrome DNG; compressed DNG, X-Trans, multi-shot, unsupported DNG opcodes, and missing lens profiles are reported or deferred. Rendered JPEG/PNG brackets are exposure-fused, not calibrated radiance. PQ/HLG display encoding and physical HDR display presentation remain unverified. Gain-map JPEG export is verified for scene-linear masters; display-linear fusion output has no extra headroom to encode and is reported as such. OpenEXR support is the verified single-part uncompressed RGB(A) subset, not a promise for every EXR variant.
