The third climb, I didn't shoot anything for a while. I just stood there.

There was a bank of cloud sitting out past the harbour mouth with a gap under it, and you could watch the gap closing. The light was coming — you could see it moving across the water toward town, that hard slab of gold that only happens late — and I had maybe ten minutes before the gap shut and it was over for the day.

It took eight. It crossed the water, climbed the hill, lit the face of the church, and went out.

I have four frames. Two of them are sharp.

The One Number I Can't Give You

Last week I handed over my base prep. Profile, blacks, whites, the calibration values down to the digit. All of it, free, no gate.

This week is the tone curve, and I can't do that.

Not because I'm holding it back. Because there is nothing to hand over; a curve that works on one photograph is wrong on the next one, and anyone selling you their curve as a fixed thing is selling you a shape that fits their picture.

What I can give you is the method. That travels.

Why the flat file was the point

Everything last week did one job: put the entire tonal range where you can see it and touch it.

That matters here because the curve is a redistribution, not a creation. It cannot recover information that got crushed at import. All it does is decide which tones get room and which get squeezed. If your blacks were already clipped, the curve has nothing to work with down there — you're just stretching mud.

Flat file first. Then this.

Where I put the first point

Not in the middle. The middle is where people go, and it's why so many edits look like the same edit.

I start at the bottom left, at the black point, because that's the decision the whole frame hangs on. Blacks are at +100 from the prep, so there is no black in the picture at all — the shadows are open, grey, sitting up off the floor. Pulling that bottom point down puts black back in, and where I put it is the entire mood of the photograph.

Drop it hard, and the frame gets dense, closed, and dramatic. Leave it high, and you get that soft, humid, open-shadow look that Portland actually has at six in the evening.

For this church frame, I left it fairly high. The whole point of that light was that it was thin and about to vanish. Crushing the shadows would have made it look like a photograph of a confident evening, and it wasn't one.

Then the top, then the pivot

Top-right point next — the white point, same logic in reverse. Whites came down in the prep, so the highlights have headroom. How much of it I take back depends entirely on whether the brightest thing in the frame is the subject or just sky.

Only then the middle. And the middle isn't really about brightness; it's about where the contrast happens. Put your pivot low, and you get separation in the shadows and flat highlights. Put it high, and the shadows go muddy while the highlights snap.

On this frame, the pivot sits high, because everything I cared about — the lit face of the tower, the terracotta roof — was in the upper half. The foliage in the foreground was always going to be a dark shape. It didn't need detail. It needed to be a frame.

Watch the histogram, not the curve

Lightroom draws the histogram behind the graph. Use it. The steep parts of your curve are where you're spending contrast, and you want to spend it where the pixels actually are. A gorgeous S-curve whose steep section lies over an empty region of the histogram does nothing at all.

And the channels

Sometimes. Not always, and not for tone.

My colour lives in Calibration — that's what last week was about. But when a frame needs something Calibration can't reach, the red, green and blue curves will do it, and they'll do it with more finesse than any saturation slider. Lifting the bottom of the blue channel puts cool air into open shadow. Pulling the top of the blue down warms the highlights without touching anything else.

It's a scalpel, and I reach for it maybe one frame in ten.

One last thing

On the finished file, Contrast in the Basic panel reads −8.

Negative. After all this.

The curve was already building every bit of contrast the picture needed, and the slider on top of it was doubling up. When your curve is doing its job you will often find yourself pulling the basic sliders back. That's not a mistake. That's the sign it's working.

A Location Note

Harbour Street, Port Antonio, late. If you want the church lit rather than silhouetted, you need the sun low and west of you, which in practice means the last twenty minutes before it drops behind the hill. The window is short, and the cloud usually wins. Go up the hill for the compressed view over the rooftops, or stay on Harbour Street and shoot up at the tower from the corner by the bridge. Different photograph entirely. Both worth having.

Reply with a screenshot of your curve on a frame you're proud of. I'll go through as many as I can.
