Filters and Photoshop


If filters are just a color lens in front of the camera lens, then can this be created in Photoshop? For example, can a new layer color - say, orange - change the transparancy so it equals a warm-up filter? Is this possible, and if so, what are the colour settings? Thanks.

  Absolutely! Determining the correct color settings is the challenge. But the nice thing about Adjustment Layers is that you can test and change settings till the cows come home. Sooner or later, you'll find a setting you like. Then, the "strength" of the setting can be further controlled with the Opacity slide bar.

  Simon, if you have PS CS in Image>Adjustments, there is a Photo Filter you can use much the same as a filter on your camera.

  When doing "colour" photography, many filter effects can be added in most versions of Photoshop (as you said). However, colour filters have a totally different effect (and use) when using B&W photography (eg: skies can be captured more intensely; shades can be manipulated more) without going near Photoshop. Though "some" of these effects can still be "edited" in Photoshop, nothing short of doing multiple layer pics and combining will allow you to control a dark or burnt-out sky. Filters are still necessary. Hope this makes sense.

  Thanks guys.

I only have photoshop 7 so I guess I need to how did Michael put it "change the settings till the cows come home". So with all that would you still buy filters for colour photos?

  You said you "only" have Photoshop 7. Nothing wrong with that mate.
Your question: Do you still need to buy filters? Answer: It's up to you. You should have a Polarizer (for starters) which effects cannot be duplicated in any Photoshop; plus maybe Skylight; Grad Filters; Neutral Density filters for control of light intensity.
If your question is purely about "colour filters" for colour photography - then I would say "probably not". But filters in general - the answer is "yes".
