I am getting the hang of Sel-Col and B & W.  done a test print and it came out quite well on draft paper.
We expect to hear from you when you win a B&W competition at your club using this layer free technique  Wink
Terry

HelloTerry.

Don't think I will win club competions, they all use such things as Nik Silver Efex Pro etc etc.

I have found another of my images which I thought could make a good B&W

The B&W rendition actions are:-

RAW.    xsc camera auto colour balance. no other adjustments

Editor.  Saturation -100
           Sel color  R-2.0, Y 0.5, G 0.5, C 0.5, B 0.5, M 0.05, N 1.00
           Levels H 224, M 0.98, S 70
           Contrast +11,  Brightness -5,  DFX 5/100 EQ
           Vignett cutout.

The colour version has been through PSE to remove a couple of fag ends!  they do not show up in B & W

posted below. artistic comments invited, now there's a gift Grin

Jeff
PS.  I have not done B & W for over 50 years!  OK I know it shows.

A good subject for B&W. I'm not convinced about the vignette, foreground looks too dark to me.
Did you use the QU vignette? I made a couple of other versions of that simply by cropping the cutout image and saving to a new name. They give a more subtle effect.
If it's any consolation, I didn't get anywhere in my club's last mono competition.  Roll Eyes

Yes Qu vignette, I try to keep within Qimage as much as possible.  I will try a couple of modified cutouts, thanks for suggestion.

Hello Terry

I tried modifying the QU cutout.

Up to now a total failure.  Cropped it OK, but it had the reverse effect, lightened the edges.

Tried to create a cutout using PSE circle gradient, bigger failure.

Any suggestions where I am going wrong?

Out for most of today, SWMBO wants to go on a snowdrop hunt to Hogstock hall,  god knows why, we have them in the garden.

It's all in the files name, check out the help on Cutouts. Help - Contents - Functions - Cutouts.
The colour of the opaque/semi-transparent part of the cutout is controlled by entering RGB values in square brackets as part of the file name.
See below [0,0,0} for black.

Two cents worth from Fred!

This is addressed to SWMBO.  My dear, my condolences for being married to this curmudgeon for so many years.

Please explain to Jeff that he is making this operation into some esoteric experience from the Kama Sutra.

Why all the numbers above. How are you setting color  multipliers when there is to be no color?

You seem to be intimidated by specialized tools that others might use.

Listen to Uncle Freddie!   

1) Select the thumbnail image of the color image that you want to change to a black and white for printing.
2) Right Mouse click it and choose Pre Defined filters.  Click on B&W
3) Open Editor and tab to Sel Color. LOOK!!!   ALL the numbers are set for you already for a perfect B&W.
4)  Adjust Tab: Reset Contrast and Brightness if needed.
5) Select Vignette Cutout
6) Now crop image and slide the crop to the position you like best. The vignette cutout will move and adjust itself.

That's it.
Print on some decent paper that doesn't have too much bluing in the whiteners and you will win!!

Please, SWMBO, read this to him a few times until he either catches on, or tells you, "Ok Stop! I will wash the windows for you dear!

His US friend,
Fred

Fred.

I think you are 'getting at me' Sad Sad

I now know why my BroadBand failed this morning.

I will explain why I am fiddling about with B&W later.

Also also pass your message on to SWMBO.

Got an appointment now with some shell fish and a bottle of white.

Right Fred.

If you refer to my original posts last August (Re Qimage Ultimate 2014.113 Last August) you will see I was not after a 'perfect B&W' what is a perfect B&W?

I attended a lecture on creating digital B & W from original colour images, the lecturer was of course using PS. and was fiddling with the colours - making reds much redder, making selections and altering the colours in the selections etc etc ending up with many layers then converting the image to B & W ending up with a B & W with tones that were not present in a basic conversion.

I, not having PS thought I bet that could be done in QI simply fiddling with SelCol.  A suggestion by Terry to start with a Saturation -100 proved that it could be done. 

I certainly get a much different result to the basic QI conversion. Whether one likes the result is a different matter.  But it did prove that QI could be so used, and was much quicker and far simpler than using PS and ending up with meg B of layers, masks, selections, nik plugins etc etc.

In the UK as far as I know, all clubs, lecturers and judges are hard wired into PS and talk/use nothing else and expect everything to be extensively PhotoShopped.  Certainly our club members achieve some remarkable images and win competitions and prizes worth substantial values.  But the images do not exist in reality and are more akin to a painting.   

Cutouts, I am still working on!! Smiley Smiley

Now be warned Fred, British wives are very loyal, so don't be surprised if SWMBO hops on a Tiger Moth and pops over the pond and sorts you out Smiley Smiley Smiley

Hi Jeff.
First of all, Same Here. Everyone who fancies himself a guru in one area or another, has to show off with PS.
We even have one fellow in a club that fancies himself the RAW image maestro.
He advocates opening a RAW image in ACR in PS, having absolutely no presets, and all sliders either zeroed or OFF!

The he starts the tweaking routine, a touch of Contrast, and a dab of brightness, and how about a pinch of Clarifier, and a level teaspoon of Luminance, some Fill light, some shadow fill in, some highlight recovery, and then save it as a TIF.
Now open the TIF  again because we need a half dozen layers for goosing colors, sharpening with Unsharp Mask, then we have to boost the colors in certain areas only, then clone out a branch. OOps! There's a dead leaf on the grass. Use Content Aware...
40 minutes later we might have an image.

This is show off stuff.
It's like me showing you my new car.
I get the crank out of the trunk (boot), set the spark for start, squeeze the bulb to get some fuel into the carburetor, and turn on the ignition.

I took the same image that the above guru was demonstrating, and inside of 90 seconds, had a better image ready to print.
But my way was too easy. How can it be good being that easy?

Such is the way people think.

Now to your B&W.  I advised that you use the Predefined B&W filter.   OK now suppose you want to play with the color channels, just for fun. This what Terry was going to tell you next.
Go into the Editor, click the SEL COLOR TAB, and now click the Load button.
You have your three primary color channel filters right there. You can load them one at a time, or however you want to play.
You can adjust the numbers ....

Last item.
I have one of those SWMBOs also.
Also from the old school, loyal and protective.
Tiger moth!?.... we have alligators in Florida.
