error46146 Posted December 26, 2011 Share #1 Posted December 26, 2011 I was thinking of buying an 81B warming filter for my camera but then I read that they can limit the amount of light entering the camera and thus forcing me to use a slower shutter or higher ISO. Is the warming filter worth it? (20 for a piece of glass is quite expensive) Are there any alternatives to it to get the same effect? Link to comment Share on other sites More sharing options...
Joe Posted December 27, 2011 Share #2 Posted December 27, 2011 All filters reduce the amount of light entering the lens in some way. This is known as the filter factor. There's a nice chart there that tells you how to translate between filter factor and "number of stops reduced". To be honest, I would skip the filter. With Photoshop (or any other image editing program worth its salt), you can add the effect in post. With a digital body, the only filter you really need is a polarizer...that effect can't be done in post. Link to comment Share on other sites More sharing options...
SoSpectacular Posted December 27, 2011 Share #3 Posted December 27, 2011 Yeah... Polarized filers are only worth looking at if you have access to Photoshop Link to comment Share on other sites More sharing options...
lilbluefoxie Posted December 27, 2011 Share #4 Posted December 27, 2011 I would recommend a UV filter to protect the lens element, in case it gets bumped or touched by mistake, you can always buy a new filter or clean it, a lens if theres damage on it, its a lot harder to fix and clean.

lilbluefoxie Posted January 3, 2012 Share #8 Posted January 3, 2012 Buy a polarizer! Absolutely 100% worth it, and the light difference is almost negligible. You have the ability to create or eliminate reflections (Photoshop can't do that), you can make glass appear as a rainbow (Photoshop can't do that) and contrast and colors are naturally boosted (if you do that in Photoshop you get grain). I've got a polarizer on all of my lenses, Hoya is the way to go and you can get one for about $20 usually. Warming filters -- you can easily do that in Photoshop. But polarizers give you stuff you can't do in Ps and protect your lens as well. Worthwhile investment. the thing to watch out for with polarizers is they arent compatible with every lens. Many kit lenses the front element rotates while focusing and that will throw off the polarizer. Link to comment Share on other sites More sharing options...
SoSpectacular Posted January 3, 2012 Share #9 Posted January 3, 2012 It's best to get a lens with a non-rotating front element since circular polarizers do have to be adjusted... And yeah you do get what you pay for! Link to comment Share on other sites More sharing options...
Joe Posted January 4, 2012 Share #10 Posted January 4, 2012 A rotating front element isn't the end of the world, you've just got to be alert of the rotation. Inexpensive polarizers tend to have high filter factor (overall) and are uncoated. The $20 polarizers (and filters in general) tend to be of dubious quality. Save up some money and spring for a single or multi-coated filter. Multi-coated Hoyas are excellent; i've got several. If your lens takes 67mm filters, let me know, I think I have one around that I can part with for a reasonable price. Link to comment Share on other sites More sharing options...

Joe Posted January 5, 2012 Share #12 Posted January 5, 2012 Multicoateds... better keep them clean Properly, might I add. You do not want to scratch the coating or the glass. Link to comment Share on other sites More sharing options...

SoSpectacular Posted January 5, 2012 Share #14 Posted January 5, 2012 Oh yeah, I picked up one of those on my last visit to Adorama, I didn't know they worked so damn good like that! Link to comment Share on other sites More sharing options...
Joe Posted January 6, 2012 Share #15 Posted January 6, 2012 Quick little microfiber cloth will do the trick for those -- that's what I swear by at least. Microfiber works well, but I would always use a puff of air (or two) from a rocket blower before wiping. Link to comment Share on other sites More sharing options...
