Help needed with effects in Photoshop - please help

I wonder if you can help me.

I used to do a bit of B&W film photography and would like to try and
replicate some of the things I used to do in B&W photography digitally.

I used to add a red filter to the front of my camera's lens and it would
increase the colour of blue's & greens. For example it would make the sky
appear dark and dramatic.

Can someone please tell me how I can duplicate the effect of a red filter to
a B&W picture in Photoshop 7?
Please keep your instructions simple as I have not used Photoshop for long.

Any help or information given will be gratefully appreciated.

I hope you can help.

Thanks!

Download "Seeing in Black & White" from Russell Brown's site. This tutorial
will tell you how to use Hue-Saturation adjustment layers to mimic many of
the effects you can get with filters in traditional (film) B&W photography.

UNFORTUNATELY he has recently converted *all* of the tutorials on his site
to QuickTime videos, which I think is a *huge* mistake.

It is just under the "Adobe PhotoShop 7.0 tips" banner.

Luckily, this tutorial is still available in HTML and PDF formats from
Adobe's site. You can get an HTML version of the tutorial at
http://www.adobe.com/tips/phs8colorbw/main.html

Or download a PDF version, again from the Adobe site, at
http://www.adobe.com/tips/phs8color...phs8colorbw.pdf

There are *many* other good resources for this subject "on the web." Use
your friendly local search engine, and you will easily find them.

A couple of useful URLs I've found this way would be

Vincent Versace presented a technique for converting color images to B&W at
an Epson seminar. Try

OK- Here is something you can try.
If you have a grey-tone image, you first have to go in File - Mode and
change the color space to RGB. Then add a new layer and fill it with
red color. Then reduce the opacity to a level where you perhaps get
something like the effect you are looking for. This is the easiest way
of doing it, but if it works - who knows? If it does not work go to
File - adjustments - Hue/Saturation, click the colorize box (lower
right) and play around with the handles. Best of luck. Edgar

Neil,

Sorry I couldn't locate your original post so I'm tacking it on the end of
this follow up in the hope thgat you are still reading the thread.

I think that your best bet would be to use the Channel Mixer.

Assuming that you are starting with a colour picture from your digital
camera, go to Image / Adjustments / Channel Mixer...

In the Channel Mixer dialog check 'Monochrome'

To give the red filter effect, increase red from it's default 100% and
decrease both green and blue by equal amounts to maintain an overall 100%
figure for all 3 channels.

For example: Increase red to 140% and Decrease Green and Blue by 20% each
(i.e. set them to -20%)

Hope that's the effect you're looking for.
