What filters for macro and portrait photography?

Hi, I would like to get the 100 Macro f/2.8L IS (will be used on a Full Frame body) for some portrait and macro work, but I amd not really expirienced in these techniques. My question is what filters, if any, are used for:

a) Macro Photography
b) Portrait Photography
c) Studio Portraits with multiple flashes

I have been reading lots and haven't found much about it so I assume it might be a silly question, but thanks for all the answers.

None that I can think of.

Oh, well ... it was a silly question than. Thanks

If you mean filters for effect, then non .. most effects can be added PP.

When doing studio portraiture, you may not be able to dial studio strobes down low enough if your intent is to do large aperture, shallow DOF work. In that situation, a ND filter may be required.


cheers,

I use three filters now for digital photography. A UV filter to protect against damage to the lens, a Polarizing filter for an effect that can't be duplicated in Photoshop, and a neutral density filter that I can use when I want longer exposures, such as making running water look misty.

For portraits I'd just use the UV as neither the polarizer nor the ND would have any beneficial effect. For macro under the right light a Polarizer might come in handy.

The effect that the rest of the filters - colour correction, split ND and so forth can usually be done better with Photoshop.

The only filters that would be used are polarizers (for artistic reasons, mainly) and neutral density filters. The ND filters would be used in portraiture, but most people buy them in sheets and put them over the strobe, not the lens.

There is no use for a UV filter, especially in a studio. What are you protecting it from?

I'm always happy to use a protect filter when I shoot macro "in the wild". I use a hoya HD protect filter, which is pretty easy to clean. I often hit branches, leaves, spider webs etc, so it's nice to have a flat surface that easily wipes clean, not to mention possible damage by sharp objects...
For studio work, I don't think you'd want any filters. Otherwise, a polarizer can be useful in the correct scenes.

Exactly. You do not have any need for UV filters whatsoever.

I put 'em on when I'm outside and take them off when I'm inside. Yeah sure. All it would take is to forget to put them back on just once and then I'm screwed if the wrong thing happened. I assume that if my lenses lived inside all of the time then a UV filter would be less important but mine - and most shooters I know - are outdoor cats as well.
