Lambda Photo is a professional color-grading editor for iPhone and iPad. Open JPEG, HEIC, or RAW, work with a live preview, and export a photo you can be proud of — including HDR HEIC that looks right on an HDR display and still holds up on SDR. Built for light, color, and skin. Exposure, Subject Exposure, and Relight give you control after the shot. HSL, curves, film looks, and .cube LUTs put color back in the image without pushing skin off-natural. Finish with subject, sky, and background masks, linear and radial grades, bokeh, grain, and Golden Hour. WHAT YOU CAN DO • Light: exposure, highlights, shadows, HDR, relight, subject exposure • Color: HSL, curves, temperature, vibrance, split tone, LUT import • Detail: sharpen, denoise, Ultra Denoise, texture, clarity • Finish: subject / sky / background, brush, linear, radial, bokeh, vignette • Looks: profiles, film, presets — plus your own .cube LUT or .dcp • Portrait: skin, eyes, teeth — edge-aware, on device • Batch export and edit from Photos or the share sheet • Formats: JPEG, HEIC, RAW, PNG, JPEG XL Everything runs on your device. No account required. Lambda Photo is free to edit; an optional auto-renewing Monthly Subscription removes ads after you save. SUBSCRIPTIONS Payment is charged to your Apple ID at confirmation of purchase. The Monthly Subscription renews automatically unless you turn off auto-renew at least 24 hours before the end of the current period. Manage or cancel in Settings → Apple ID → Subscriptions. Unused portions of a free trial, if offered, are forfeited when you purchase.
