Just a suggestion: next time use a tripod, install two linear polarizers set the camera to ISO 80, shutter priority about 3.5 seconds. It should be quite a picture

What is the purpose of using "2" linear polarizers?

My concept is to catch the diver on take off al the way into the water. In order to be able to shoot at ISO 80 with a speed 3.5 seconds it is necessary to knock out a substantial portion of light entering the lens. Stacking two linear polarizers creates a variable ND filter where you can control the light from a four F stop loss to total darkness. Without the two linear or an ND +8 filter the proposed shot is impossible; too much light. I would also frame the shot like this.

When two LP are stacked and used in combination positioned at "nearly darkness" there are a lot of secondary effects on image colors.
And it would need many tries to understand the correct long exposure in any given position of the 2 LP. Hard but not impossible.

I have used 2 Pol in cascades shots to achieve the "silky water" effect using 8 sec. exposures with my FZ20 already in the shade.

Yes but this is different.

Thiswould be my process.



The shot time is fixed being a retired diver it looks like 2.5-3 second shot.

Set the camera to manual mode with spot metering and manual focus.

Set the camera to F8 and 2.5 seconds.

Aim the camera at the diver.

While half depressing the shutter rotate the front polarizer until the dial on the bottom in the EVF is in the middle.

Focus the camera on the diver by using the manual mode button on the barrel. Re-check the setting my half depressing the shutter button

Now all the settings are locked in.

Reposition the camera on the tripod to the correct shot position.

The hardest part is firing the camera at the correct lift off time.



I am not pushing the envelope to that extent with an under 3 second shot. You will need PP software that has a good W/B feature. Polarizer shots always need W/B adjustments.
