Most light planning tools are dashboards in disguise. They hand you numbers and leave the thinking to you. Sunrise at 07:04. Cloud cover 68%. UV index 3. Perfectly accurate. Completely useless.
BYgo reads the conditions and produces a shooting brief. Not a chart. Not a forecast. A decision with the specific windows worth your time, what to look for in each one, and which photographers built careers working in exactly this light.
Every city. Every condition. Every time of day. The brief changes when the conditions change. It is never the same twice.
See your brief now →The sky has turned itself into a softbox and it belongs to you. Light arrives from everywhere at once, wraps around faces, finds no shadow worth hiding in. Point the camera at a person. Any person. Any time of day.
The kind of day Chris Killip spent his career waiting for in northeast England. He never complained about the weather.See the work →
The moment when interior lights become visible against the outside sky. Windows glow. The city goes dark around them and the windows are the only thing that matters.

Before You Go tells you what the light will do. After the Shot tells you what it did. Drop in any photograph and BYgo reads when and where it was taken, then works out exactly where the sun was, what the sky was doing, and how many minutes of that light you had.
Then it tells you the next date the same light comes back to the same place. Save it and we write to you the day before.
Read a photo →Low sun, a lot of cloud. The kind of light that goes soft and gold at once, and does not hang about. You had roughly twenty minutes of it.
"I checked BYgo before heading out on a grey Tuesday morning. It told me the overcast was the point, not the problem, and referenced Killip. I went out. It was one of my best sessions."
"I was about to cancel a shoot because of cloud cover. The brief told me to go anyway and explained exactly what to look for. I came back with the best frames I have made this year."
"The film recommendation matched the conditions precisely. I loaded Portra 400 instead of what I had planned and the results made sense in a way they usually do not on overcast days."

Try BYgo →Not often. Never pointless.
