Existing relighting methods either rely on multiple input views to perform inverse rendering at inference time, or fail to provide explicit control over light changes. Our method fine-tunes a diffusion model on a small set of real raw photograph pairs, supplemented by synthetically rendered images at scale, to elicit its photorealistic prior for relighting. We leverage the linearity of light to synthesize image pairs depicting controlled light changes of either a targe","authors_text":"Alex Rav-Acha, Amir Hertz, Ariel Shamir, Eric Tabellion, Nadav Magar, Yael Pritch, Yedid Hoshen","cross_cats":["cs.GR"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CV","submitted_at":"2025-05-14T17:57:27Z","title":"LightLab: Controlling Light Sources in Images with Diffusion Models"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2505.09608","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:c00f7fc4cfc894c5bf03249b72f4e6e57027855e712debd88ab21018c804500a","target":"record","created_at":"2026-07-05T11:03:11Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"fc8d7910d3878463db11d1d932621241a8ab25b6f081c454487e33514461b005","cross_cats_sorted":["cs.GR"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"cs.CV","submitted_at":"2025-05-14T17:57:27Z","title_canon_sha256":"84ab2cbab0ae07996b88a3ed0dbaa57953f7974180d21ffdb742d4f66048e56f"},"schema_version":"1.0","source":{"id":"2505.09608","kind":"arxiv","version":1}},"canonical_sha256":"56f05b8413c4878e2c946e24bd6ff930d300fc0d95e19577b9372fef750fd30c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"56f05b8413c4878e2c946e24bd6ff930d300fc0d95e19577b9372fef750fd30c","first_computed_at":"2026-07-05T11:03:11.283404Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:03:11.283404Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"I7q6kToXO4nwbBvpfy35z/VwnkyEeJ/76eUtWkNGyrzxOGLQ8RQeWJKntwynq3uHG19th1M+N/gYAEwzWFuuDA==","signature_status":"signed_v1","signed_at":"2026-07-05T11:03:11.283875Z","signed_message":"canonical_sha256_bytes"},"source_id":"2505.09608","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c00f7fc4cfc894c5bf03249b72f4e6e57027855e712debd88ab21018c804500a","sha256:f4d9c7266a3bbbfe7a1ff96e9f1d4678abc59e5877ec57d2aced8ef6f6c78e64"],"state_sha256":"99d3b4c9ef0edd5de851ca903b248c784fe645b61626f39dea92f4f7da4cf83a"}
