Lambda Photo vs RawMask Studio

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.

Edit only the part of the photo you choose. RawMask Studio is a RAW photo editor built around masks: pick a detected subject or draw your own mask, then change the light, color, detail and focus of just that area while the rest of the image stays untouched. It opens RAW and ProRAW files as well as everyday JPEG and HEIC photos, and every edit happens right on your iPhone. MASKS FOR SELECTIVE EDITS - Automatic masks: on-device detection finds subjects such as people, cars and animals and turns them into ready-to-edit masks - Manual masks: radial, linear (gradient), brush and rectangle - Refine any mask with the Add and Subtract brushes - Soften the edge with Feather for smooth, natural transitions - Give every mask its own light, color, detail and focus adjustments RAW, PRORAW, JPEG AND HEIC - Pick photos straight from your Photos library with the system picker - Edit RAW and ProRAW captures with the same tools as regular photos A CLEAR, STEP-BY-STEP WORKFLOW - Frame: crop, straighten, rotate, aspect ratios and zoom - Light: exposure, contrast, highlights, shadows, whites and blacks - Color: temperature, tint, vibrance and saturation - Detail: texture, clarity, dehaze, sharpness and noise reduction - Focus: background blur with strength, range, feather and bokeh - Effects: vignette, grain and fade - Reorder or hide steps in Editor options to match the way you work COMPARE AND REUSE - Hold to Compare to check before and after at any moment - Save whole-photo adjustments as a Preset and apply it to another photo SAVE WITHOUT LOSING THE ORIGINAL - Save edit to Photos is non-destructive: the original stays intact and you can revert the edit in Photos anytime - Save a copy to Photos to keep the edited version as a new photo - Export as JPEG, HEIF or TIFF through the share sheet PRIVATE BY DESIGN - No account, no sign-in and no ads - Editing and subject detection run entirely on device, so your photos are never uploaded - Free, with no in-app purchases Open a photo, pick a mask and make one part of it shine.
