A job photo is worth more when you can say where and when.

Every shot SiteProof takes carries four things with it: the moment the shutter fired, the coordinates the phone was standing on, the street address those coordinates resolve to, and whatever you typed against it. They print under the photo in the report and burn into the picture when you share it.

A SiteProof photo opened full screen with its capture date, time and street address listed underneath

What gets stored next to the picture

The image file itself is left exactly as the camera produced it. Everything else lives beside it in a database on the phone, tied to the project you were shooting for. That separation is why a photo can be re-shared, re-printed or pulled into a different report later without the original ever being rewritten.

The record behind one photo
Field	What it holds	Editable later
Capture time	Device clock at the moment the shutter fired, printed as “March 14, 2026 at 2:41 PM”.	No
Coordinates	Latitude and longitude to six decimal places, with N/S and E/W, from the handset’s GPS.	No
Street address	Street, town and region, looked up from those coordinates. Needs a connection.	No
Note	Whatever you type against the shot — the room, the trade, what the client asked for.	Yes

Open any photo and those fields are listed under it, along with the project it belongs to. Coordinates show in full — six decimals with N/S and E/W — rather than the rounded form used in print.

How the location is taken

SiteProof asks the handset for a high-accuracy fix and gives it fifteen seconds. GPS is satellite work rather than internet work, so a fix usually still arrives in a basement, in a field, or anywhere the mobile signal has given up. The reverse lookup that turns those numbers into “12 Mill Lane, Leeds, West Yorkshire” is the part that wants a connection, and it is the part that goes missing first.

If location services are switched off, or you declined the permission, or the fifteen seconds run out, the photo is still saved. It simply carries no coordinates and no address, and the report prints the time only. Nothing is blocked and nothing is silently discarded.

Coordinates describe where the phone was, not where the fault is. On a large site that can be twenty metres apart, and under a steel roof it can be more. The note field is there to close that gap: “rear elevation, second floor, north corner” tells a reader something a decimal degree never will.

What is actually written onto the image

Sharing a photo produces a stamped copy. The original stays where it is; the copy is a PNG built on the spot with a dark band drawn across the bottom of the frame.

1 First line: the moment. The full capture date and time, in the same wording as the photo details.
2 Second line: the place. The street address if one was found. If not, the coordinates go there instead, rounded to four decimals so the line stays readable.
3 Bottom right: SiteProof. A small app credit, so a photo forwarded on still says what made it.
4 The message carries it too. The share text repeats the project name, the capture time and the location, for anyone reading in a chat window rather than opening the file.

The stamp is generated at share time from the stored record, which is why editing a note or re-sharing months later still produces a correct band.

What survives into the PDF

A report is built from photos you pick out of a project. Each one prints as a card: the image, then a grey block underneath carrying the capture time, the coordinates at four decimals, the street address and the note. Any of those four can be switched off for a given report if a client does not need them.

Ahead of the photos sits a cover page with your company logo and name, the report title you typed, the client, the site address, today's date and the photo count. Two photos to a page is the default; one to a page gives a much larger image where the detail matters. Every page after the cover is numbered and carries the project name in the header.

Where each field ends up
Field	On the shared image	In the PDF
Capture time	Yes, first line	Yes, full precision
Coordinates	Only if no address was found	Yes, four decimals
Street address	Yes, second line	Yes
Note	In the share message, not the band	Yes
Mark-up	Kept with the photo	Kept with the photo

Mark-up is freehand, arrows, boxes, circles and text, drawn over the shot and stored separately so the original photo is never painted on.

Before you rely on it

This is a record you made, on a device you control, and it can be edited or deleted by whoever holds that device. It reduces the arguments that start with “when was this taken?” — it does not settle them, and it is not evidence in any legal sense. Contracts, variations and disputes are decided on paperwork and on what was agreed, and a photo log is a supporting document alongside those, nothing more.

For the wider habit — what to shoot, when in the job to shoot it, and how to keep a set that reads well six months later — there is a longer piece at the job site photo documentation guide.

Why it is worth the extra second

Nothing to remember. Time and place attach themselves. There is no field to fill in.
Readable by anyone. A street address means more to a client than a pair of decimals.
The original is never touched. Stamping happens on a copy, at the moment you share.
Underground and out of range. Satellite fixes do not need the mobile network to arrive.
Filed as you shoot. Each photo lands under a project instead of the camera roll.
No account. The app opens on your projects. Signing in is optional.

Questions

Does SiteProof stamp the date and GPS onto the picture itself?

When you share a photo it makes a stamped copy: a dark band across the bottom carrying the date and time, the address or the coordinates, and the app name. The file kept on your phone stays untouched.

How accurate are the coordinates?

They are whatever your phone reports at high accuracy within fifteen seconds, stored to six decimal places. That is where the handset was standing, which on a large site is not always where the defect is.

What happens if there is no signal on site?

The photo, the time and the coordinates are all recorded, because GPS comes from satellites rather than the network. The street address is the one part that needs a connection, so it can be missing.

Can I add a note to a photo after the event?

Yes. Notes are editable from the photo viewer at any time. The capture time and the coordinates are written once and are not editable.

Does a timestamped photo count as proof?

It is your own record, made by your own phone, and it can be edited or deleted by whoever holds the device. Treat it as documentation of what you saw, not as evidence that settles an argument.

What do free reports leave out?

One project, ten photos a month, and five photos per PDF. Free reports also print without your company name and logo. Nothing already captured is hidden or deleted.
