How Photography Studios Transfer Large RAW Files Between Editing Computers

The Photography Studio File Size Problem

A single RAW file from a modern medium-format or high-resolution full-frame camera runs 50–100MB. A full-day portrait shoot with a 60MP camera produces 2,000–4,000 images. That is 100–400GB from a single session.

Cloud sync is not built for this. Uploading 200GB to Dropbox at 50 Mbps takes over nine hours. You cannot give a client same-day selects with that workflow.

Professional studios — even two-person operations — use local network transfer for moving files between the shooting tethered laptop, the culling station, the retouching machine, and the output computer. This is not a workaround. It is the industry-standard approach for any studio doing meaningful volume.

Understanding the Photography File Workflow

Files move through stages, and each stage may involve a different machine:

Capture → Ingest: Camera CF/SD card or tethered laptop → ingest station or main edit machine. For tethered shooting, Capture One or Lightroom saves directly to a designated folder.

Ingest → Culling: The raw ingest (all files) moves to the culling station or stays in place for the main editor to cull. At this stage you are working with previews and embedded JPEGs — the full RAW may not need to move immediately.

Culling → Retouching: Selected images (culled RAW files, possibly with first-pass edits as exported Capture One sessions or Lightroom smart previews) move to the retouching machine.

Retouching → Output/Delivery: Finished TIFFs or JPEGs — often 100–200MB per image at full resolution — move to the output machine for client gallery uploads or print preparation.

Option 1 — Tethered Shooting Directly to a NAS

For studios where the editing machine is in the same room as the shooting area, shooting directly to a NAS means the images are immediately accessible from every machine:

1. Connect the camera tethering cable to the laptop running Capture One or Lightroom
2. Set the capture folder to the NAS path (e.g., N:\Sessions\ClientName\2026-04\Capture\)
3. The NAS receives images directly; the editing machine can watch the same folder in real time

This requires a fast network connection at both ends. For sustained tethered shooting, wired gigabit (or 2.5GbE) between the NAS, the tethering laptop, and the main edit station is recommended.

Option 2 — Ingesting to Local Drive, Then Transferring to Edit Station

Many studios prefer to ingest to a fast local drive first (for speed and reliability during a busy shoot), then transfer to the editing station or NAS afterwards.

The local-first then LAN transfer workflow:

1. Cards are ingested to a local fast drive (NVMe SSD) on the ingest laptop
2. After verification (checksums, file count), the session is transferred to the editing machine or NAS over LAN
3. The local ingest copy is kept until delivery confirms the transferred copy is intact

For this transfer step, LAN speed matters. At gigabit ethernet, 200GB transfers in approximately 30 minutes. At 2.5GbE, around 12 minutes.

Tools like Oxolan handle direct machine-to-machine transfer without requiring shared folder configuration on either end. Select the destination machine, drop in the session folder, transfer runs at full network speed.

Option 3 — Shared NAS as the Studio's Single Source of Truth

For studios with two or more retouchers working simultaneously on the same session — or any studio that needs all machines to see the current state of a session — a NAS as the central storage handles simultaneous access.

Recommended NAS setup for photography:

• A Synology or QNAP NAS with at least RAID 1 (two drives mirroring each other) for redundancy
• Connected via wired ethernet to a switch that all studio machines connect to
• Shared folders structured by client and date: /ClientName/2026-04-15/RAW/, /ClientName/2026-04-15/Selects/, /ClientName/2026-04-15/Exports/

For retouching directly from NAS (rather than local edit-and-sync), the connection speed needs to keep up with reading large TIFFs. Gigabit is sufficient for retouching standard JPEGs and TIFFs. For working with 16-bit 61MP TIFFs in Photoshop, 2.5GbE or 10GbE makes a noticeable difference in file open times.

Backup Discipline for Photography Studios

This deserves a brief mention: the moment images leave the camera card, a backup should exist. No file should exist in only one place at any point in the studio workflow.

Practical minimum for professional studios:

• Copy 1: Working drive (ingest laptop, NAS)
• Copy 2: Second local drive or second NAS (RAID is not a backup — it is redundancy)
• Copy 3: Offsite or cloud (for disaster recovery only — not for day-to-day access)

The 3-2-1 backup rule (3 copies, 2 different media types, 1 offsite) is the standard. The offsite copy can be a cloud backup service for the final archived deliverables — size is manageable when it is JPEGs, not RAW.

Frequently Asked Questions

Is it faster to ingest from a card reader to NAS directly, or local drive first then transfer? Local drive first is typically faster for the ingest step itself (card readers top out around 300 MB/s; local NVMe is faster). The total time (ingest to local + LAN transfer) may be similar to direct-to-NAS ingest. The advantage of local-first is that card reading failures are isolated from network issues.

Can Lightroom and Capture One work directly from a NAS? Yes, both support network paths. Performance depends on network speed and the size of the files being worked on. Previews and smart previews in Lightroom are particularly effective for NAS-based workflows, allowing fast browsing with the network reading only the full RAW when needed.

What network equipment do we need for a two-person studio? A gigabit-capable router or switch (most modern office routers are gigabit), two Cat6 cables, and a NAS or shared machine. If you're working with large-format files regularly, a 2.5GbE switch (ASUS XG-U2008 is approx $90) and 2.5GbE adapters for each machine meaningfully improve throughput.

How do we send a finished gallery to a client? This is separate from the studio's internal workflow. Options include: a gallery platform (Pic-Time, Pixieset, Shootproof), a cloud storage link (Google Drive, WeTransfer), or a physical medium for very large commercial deliveries. Local network sharing handles internal studio workflow, not delivery to external parties.
