Digital BW, The Print

Is there a way simulate the use of a red filter in Photoshop? There has 
to be away. I have been playing around with the idea, but cant not 
think of a good way to do it.

Thanks

Steve

Use the channel mixer on a color image, full red to monochrome.

The key term here is color image.  Once it's in grayscale, you no longer
have that option.  B&W film is color sensitive; a red filter allows red
light to pass but not blue.

This link was mentioned last week:

If you can, download or watch the Quicktime Movie "Seeing in 
Black and White",  it's pretty awesome. I have not tried this 
technique yet, but it could be the best way to convert a color 
image to B+W. It also comes in a PDF.

Best,

TRY THIS: open your color image in rgb. go to "window"/show channels. 
the channels dialogue box will appear. you will have the rgb image, a 
red channel, green channel and blue channel. click on each image and 
it will come up full size. you now can view how the image will look 
with a green filter, blue filter and red filter. the red filter is 
not always the most appropriate for an image. the green filter is 
many times the most pleasing for landscape. only problem is you 
cannot simulate the yellow filter. very often the blue channel will 
be awful and full of noise.

in lanscape photography each of the filters, blue ,green ,red has a 
profoundly different effect on the image since the filters control 
the area of the spectrum reaching the film. if you shoot with color 
film you can get this effect in photoshop with one image using the 
three different channels.

Fill a layer with red and use the Color blend mode.

I use the Russell Brown technique and it is awesome.  Once I truly
understood it, I came to the conclusion that the only way to get a
(digital) black and white image is with a color image.  The filter control
is limitless.
