As we know, "Enhance > Convert to Black and White" is the default BW conversion command in PSE. It includes 6 handy presets that can be fine-tuned as needed.
Actually, the tool is quite good.
However, there are two important restrictions:
1. We can't apply this correction as adjustment layer.
2. We can't save custom BW presets.
If you have achieved a great BW effect of your own, inability to reuse it may be pretty annoying.
The funny fact is that, under the hood, this tool is just a skin for old good "Channel Mixer".
So, with a little help of Elements+, all the restrictions can be bypassed as follows:
1. Go to "Enhance > Convert to Black and White", choose a preset and adjust the settings as needed.
For example, on the screenshot below, I start with "Infrared Effect" and modify it.
2. If you don't use
Shortcuts+ run this script now.
3. Press [Alt+Shift+Ctrl+M] keyboard keys (on a Mac: [Alt+Shift+Cmd+M]).
This opens "Channel Mixer" dialog with the last used settings.
By a strange coincidence, these settings exactly reproduce the result of using "Convert to Black and White" tool.
(in our example, the customized "Infrared" effect)
Click "gear" button and save a new preset (screenshot).
For example, under the name "My Infrared".
4. Now, to reuse the BW effect, just run E+
Channel Mixer command and load the saved preset (screenshot).
As result, we have the same BW conversion applied as an adjustment layer.
