Client proofing: watermarked previews that don't insult the client

Watermarks sit in an awkward place. Too subtle and the client crops them out or screenshots the preview, posts it without paying, and you've lost leverage. Too aggressive and the client feels accused of theft before they've had a chance to pay. The sweet spot is a watermark that makes unauthorized use obviously stolen, without making the client feel like you don't trust them.

What watermarks protect

A watermark is not theft-proof. Anyone with basic Photoshop skills can remove a watermark from most photos in under five minutes. Content-aware fill is a free feature on every client's phone now, and it erases even moderately complex watermarks.

What watermarks actually do is two things. They signal that this is an unpaid preview, which is useful for your own tracking and for reminding the client. And they make "casually reposted" uses look bad: when the watermark survives a repost, anyone who sees it knows the repost is unauthorized.

Watermarks don't stop a determined thief. They stop lazy theft. That's most theft.

Low-pressure watermarks

For client preview galleries, the watermark should be small, semi-transparent, and in a corner. Your logo or studio name, 40 to 60 percent opacity, in the bottom right. Size it at about 4 percent of the image width.

The client opens the gallery, sees your brand discreetly placed, and doesn't feel the preview is compromised. They can still see the color, the composition, the expression on the subject's face. They can make a buying decision without being annoyed.

Avoid center-stamping. Avoid huge diagonal "PROOF" text across the entire image. These read as "I assume you're going to steal this," and some clients read it that way too. The reality is that nine out of ten clients are honest and paying, and you don't want to treat them like suspects.

High-pressure watermarks, for published previews

If you're posting a preview to a public channel (Instagram, a blog, a Facebook album you've shared with the client's wider family) the pressure level is different. The watermark now needs to survive a screenshot-and-crop. Place the watermark in multiple positions: one in a corner, one subtly integrated into a non-critical part of the image (across an out-of-focus background, for example).

Some photographers use a tiled transparent watermark at 10 to 15 percent opacity across the whole image. Barely visible on the photo, impossible to remove without retouching every square inch. Reserve this for genuinely public-facing previews where the theft risk is real.

For video previews, watermarks should be animated subtly. A logo that fades in and out at 3-second intervals is harder to motion-track out than a static overlay. Use a corner position and keep it at 60 to 70 percent opacity.

The preview-resolution question

Don't send full-resolution previews. Ever. A watermark on a 6000-pixel-wide file is easier to remove than one on a 1200-pixel-wide file, and a client doesn't need 6000 pixels to make a buying decision.

For photo previews, 1200 pixels on the long edge is the sweet spot. It's large enough to see detail on a laptop or tablet. It's too small to print at a usable size. It recompresses cleanly to Instagram size without killing the visible quality. Anyone trying to steal it gets a 1200-pixel file that looks soft at any serious print size.

For video previews, 720p at 5 Mbps is the preview standard. It's watchable on a phone or laptop. It's too compressed to edit or re-use without visible artifacts. And at 5 Mbps, a two-minute preview is about 75 MB, uploadable in under a minute on a decent line.

The expiring-link trick

Modern transfer services let you set expiration on download links. Seven days is standard for client proofs. The client gets the link, reviews the gallery, and if they haven't responded in a week, the link goes dead. They have to ask again, which becomes a useful conversation trigger.

For proof galleries specifically, also password-protect. Not because the client is a security threat, but because the link can leak (forwarded emails, screenshot share to a family group chat). A password adds one layer of intentionality.

I sent an un-passworded, non-expiring proof link in 2022 and found it shared in a WhatsApp group the bride's cousin ran, with 30-plus members I'd never met. Nothing was stolen (the watermark held up), but it became clear to me that "just a client preview" isn't a single-audience document.

Branding, because the preview is also a pitch

A well-watermarked preview is itself marketing. Every family member the client shares the gallery with sees your brand sitting on every photo. For wedding and event photographers, previews circulated to extended family are one of the best referral channels that exists.

Keep the watermark consistent with your main brand: same logo, same font, same positioning across every delivery. Don't redesign your watermark per project. Consistency compounds.

Delivery format

PDF with embedded images is the easiest review format for non-designer clients. See sharing Figma designs with clients who don't use Figma for the general case. For photos, a client-review PDF with 40 to 100 images, each at 1200 pixels, is usually 30 to 80 MB. Send the preview directly and the client opens it in their PDF reader without friction.

For photographers delivering high volumes, a gallery system (Pic-Time, Pixieset, ShootProof) beats a flat file delivery. Those tools handle watermarking, download tracking, and expiration natively. Use a transfer service for the RAW handoff after payment, and the gallery for the preview.

The volume note

If you're doing heavy preview-and-delivery workflows, the pricing page has options built for photographer volumes. For a related read on the post-payment delivery, delivering 500 RAW photos to a wedding client covers the full-gallery handoff.
