Hi,
I attach a jpg of an image I am trying to edit.
My intention was to cut out all the background.
I wanted to take photographs of owl feathers floating to earth.
I need a large DOF because the path of the feather was erratic and I needed detail. The subject was moving to I needed a fast shutter speed. Noise would be a problem so I needed a low ISO.
It had to be indoors because the slightest breeze deviated the feather,
To establish a constant dropping point I attached a button to a thread and hung it from the ceiling.
I was using a Macro prime lens so I set up my camera far enough from the thread to try and get as much of the frame filled with the falling feather.
I ended about 1,8m away. The background was heavy closed curtains about 3m behind the thread.
I set up a flash at right angles to my field of view, about 1m from the thread. The flash was set to manual at full power.
I set up my camera at 1/250th, f=22 ISO 100. Fully Manual. I was trying to cut out all ambient light and use the duration of the flash as my exposure speed.
To pre-focus I had my son hold the feather just below the button on the tread and took a photograph.
Trying to synchronise the shutter release with the moment the feather passed through the field of view took a little practice.
I was able to get a few acceptable images.
When it came to processing I found that I liked the the image of my son's hand holding the feather more than the others.
This the image attached.
I have processed the image in ACR leaving the WB as shot.
I then adjusted the Colour in Elements 2018 Editor.
Unfortunately the are bands of light visible which correspond to the folds in the curtains in the background.
Some light from the flash must have bounced off the walls and ceiling.
I can't adjust the shadows without changing the Colour balance ( or can I ? )
I have tried, unsuccessfully, to select the subject detail.
Any help in removing the banding will be appreciated
