G'day,

In the LL Camera-to-Print video chapter 14 on softproofing, Jeff Schewe shows some adjustments to image in softproofing. One of these is to "punch the blacks" and he uses the "select color range" with a modest fuzziness and copies those selections to a multiplied layer. That result works well with me except that it is not a re-editable parameter. Is there a functional equivalent that I can use that allows me to go back and tweak this "punch blacks" adjustment without doing it over with a new layer? Do folks have a method with a "Selective Color" adjustment layer or something like that?

Cheers, Ralph

You can vary the initial fuzziness in the first place, the opacity of the resultant multiplied layer or go into the blend if options and vary things there. You can also add a layer mask to get rid of any areas that don't help the image. Pretty wide range of modifications...

not to hijack this thread, but it has to do with the punching the blacks technique, so here goes..

i know a few printers who as a final step before printing are modifying the black point via a curve [only a few points, like 10 [ they're getting said reading from printing a gradient]] and setting it to a blend mode of luminosity to hopefully open up some of the blacks in the print. If that technique was done in addition to "punching the blacks" are you in result negating the effects?

thanks

Sure would...

But one could adapt the punch black to select about 25 and below 100 and pop that results to a new layer and set to screen (with a lower opacity) to lighten up the darker tone while still keeping blacks to be black.

very cool, i'll play around with that when i have time. In your humble opinion are you not a fan of messing with the blackpoint value?

Why would I???

I'm a visual artist, I really don't care about numbers so much as what the image looks like. So, I never fall in love with "numbers".

The "punch blacks" that you speak of in the LL Camera to Print Video and also in the Epson Print Academy, is this the same as running Punch Blacks from Phototkit?

Would you advise not utilizing the Photokit Punch Blacks for softproofing?

So am I correct in understanding you to say use the Photokit Punch Blacks for softproofing?

That's the trouble with double-negative questions, isn't it?

PS: you have some lovely stuff on your web site, but I'm particularly intrigued by the tiny shot you use as your icon here. Do you have a larger version?

Yes, use whatever allows you to get the image the way you want it to do...

Yes, but it was ultimately clarified

Thank you. The icon image is a staircase in a hotel in Perugia, Italy. In Lightroom, I desaturated all colors except red. If you follow the link Brufani Palace Hotel Staircase it should take you to the gallery page with the image enlarged on the right. If you hover on the right side of the large image, you will have a choice to view in larger sizes.

Regards,

Is this technique also valid for B&W images?

Edit: Seems like it does
