Filters for DSLRs?

[Tapeman]

I have been planing to add warming and color correction filters to my gear.

Will I need these as much for digital as for film? I expect to use my polarizers and ND filters as before.

My lenses take 77mm filters.(pricy)

I don't have my DSLR yet but my investment in Canon lenses locks me in to Canon.

I like my Leica Digilux but it is very limiting after shooting with my 1v & L lenses.

If you get Photoshop CS you can literally add the warming or cooling filters later in the regular part of PS, under Adjustments, Photo Filter. They even name them Warming filter #81 & #85, and Cooling filters #80 & #82. You can also adjust the density of each filter to give you almost infinite control.

Without the specific filter numbers you could also control the colour temperture of the RAW file as you decode it.

Will this work as well as using a glass filter? I really don't see why not.

You'll find colored filters will provide unexpected results. Unlike film cameras, digicams have a full time white balance feature. The white balance is always searching for the white point and adjusting the colors accordingly.

You can accomplish color correction on camera using the white balance settings. This compensates for things like direct sunlight, shade or tungsten lamps.. With the 10D, you can also adjust the color temperature in Kelvin.

If these things don't work, then you can usually get by with post processing software. As DaveG indicates.. Photoshop is good for this...

The only useful filters I've found are:

Clear UV (lens protection),
Neutral density
Polarizing... (circular)

With Photoshop CS, I do all my colour correction there (including grads).

Only physical filters I now use (my work is mainly landscape/skyscape/sunsets) are:

Circular Polarisers (round, screw in)
ND (round screw in)
ND Grads (Cokin and Lee square filters)

I couldn't live without those and they produce something you cannot recreate in Photoshop.
