A photographic collection, one deliberate workflow
PRVKIT Studio takes a local collection through Import, Look and Delivery. Start with photographs from your device, decide whether they need a shared grade, and prepare the requested output versions and documents. Review is optional. You can also use Quick Grade when the job only needs a LUT and a direct batch export. The same application supports those paths without requiring a separate project upload or cloud gallery.
The default is to keep an existing edit with no LUT. That matters when your photographs have already been finished elsewhere: organizing a delivery should not quietly impose another color treatment. Original files are never overwritten. When you explicitly choose untouched copies, their original bytes and embedded metadata remain; that choice is different from re-encoding photographs without source identifying metadata.
Import a manageable job
Choose images or a folder and give the project a useful name. Studio accepts still PNG, JPEG and supported HEIC/HEIF. Header inspection and bounded previews avoid opening every source at full resolution simultaneously. Selection admission permits up to 1,000 images, 100 MiB per source and 5 GiB of selected bytes. Processing has a separate 64-megapixel, 16,000-pixel edge tier and additional memory, codec and destination limits.
Those numbers are ceilings, not a claim that a thousand maximum-resolution files work on every device. A large file can be refused before decoding, or a supported format can exceed the current operation budget. Safari and Chrome have different practical limits. Keep the source folder intact, review skipped files and try a representative selection before preparing a substantial delivery.
Select photographs intentionally. Included and excluded states affect delivery without deleting originals. Optional review can help you organize attention, but it is not an aesthetic culling judge or a promise to detect every blink, focus error or unsuitable frame. Compare important images at original detail before deciding what to include.
Make the look while looking at the photograph
Four real samples provide a representative view of the collection. Replace samples when they fail to cover difficult lighting, skin tones, bright clothing or deep shadows. A single attractive frame can hide a grade that clips highlights or shifts color elsewhere. Before/After comparison is most useful when you move between genuinely different parts of the job.
Choose one of the eight PRVKIT starter looks or upload a supported 1D or 3D .cube file. The LUT reader admits bounded files up to 12 MiB and 65-cubed grids. Use LUTs appropriate to your source photographs. A camera-log or HDR conversion LUT does not become suitable for ordinary SDR images merely because its file parses correctly. You also remain responsible for permission to use and distribute any custom LUT.
The main controls are LUT Strength, Exposure, Contrast, Saturation, Blacks and Whites. Advanced Adjustments contains Temperature, Tint, Highlights, Shadows, Fade, Clarity, Vibrance, Sharpness, Grain and Vignette. Start with strength and exposure, then assess the contrast endpoints. Add spatial effects sparingly: a small proxy can make sharpening or texture appear different from an original-size view.
Original detail is a real full-resolution view within the admitted budget, not an enlargement of the proxy. It retains one Before or After frame and regenerates the other when needed. Use it for hair, fabric, shadow noise and fine edges. Preview scale remains a convenience; final judgement should include the intended delivery size.
Know which photographs receive the recipe
Continue captures the current look for the displayed scope. A selected set can receive one recipe while other included photographs retain another. Multiple looks keeps an explicit Apply action. Check the scope and applied state before moving to Delivery; changing a sample is not the same action as assigning a recipe to the whole collection.
Save a look to your device only when you want it persisted. A saved look contains settings, seed and LUT data, not the photographs or filenames. Portable preset export is a separate local file. Delivery settings have their own optional saved recipe; photographer details are saved only through the explicit brand-data option. Reloading does not restore selected photo references automatically.
Prepare something a client can understand
Delivery can include original-size photographs, smaller sharing copies and optional photographer-branded welcome and photo-index PDFs. Choose requested versions before judging the expected count. Two versions of ten included photographs mean twenty photo outputs, plus whichever documents you selected. Review naming and the folder arrangement so that the recipient can tell the full-resolution and sharing versions apart.
Photographer branding belongs in the welcome document: use the actual name, contact details, message and permitted logo or signature. Check spelling and contact information in the generated document. A photo index is useful for identifying a particular photograph, but it is not an online client gallery or a delivery service. You transfer the finished local package using your own chosen method.
Verification checks the requested outputs and package structure before reporting readiness. It does not prove the browser saved every part or that your client received it. Inspect warnings, skipped files and requested counts, then open the saved files and archives yourself.
Export with access and memory in mind
All previews, adjustments and presets are Free. Batch export requires monthly PRO at €8.89 per calendar month or the €2.99 Studio Day Pass, which grants exactly 24 hours of Studio export and no Converter or Editor PRO rights. Account verification and payment are separate from local photo processing. Sign in with your purchase email to restore verified access.
PNG and JPEG use browser encoding; WebP uses the reviewed local encoder. JPEG applies the chosen background to transparency. Supporting browsers can write to a local folder. Independent ZIP parts are bounded at 128 MiB each, and Quick Grade also offers a supported streamed ZIP path capped at 1 GiB. Download each part before continuing. A single oversized output needs another supported destination or an explicitly smaller recipe; Studio does not silently lower quality to fit it.
