Filter Question
I hear people talking about a filter they use for bright sunlit areas. I have a uv filter on all of my lenses but what is the lens that I here others talk about that helps out in the bright sunshine?

Hi Corky, It's Lynne again. Perhaps people are talking about a polarizing filter, which can saturate blue skies on a sunny day and can remove reflections from shiny surfaces. You can control these effects by rotating the outer ring on a polarizing filter. Just resist the temptation to oversaturate blue skies. A UV filter is important to have on all your lenses for protection, but it won't make a significant difference on the appearance of your images. Any other input from anyone?

I had a question about resizing images and got a response but didn't really understand what he meant. I've been told not to resample, but my question was what is the best method to get a smaller version of your original when you need to submit it online or send it in an email? Thanks for all your input. You have really helped me.

Hi Corky, I think that Richard was trying to emphasize the importance of keeping the original image as a large file, while creating a duplicate to resize to a smaller size. I know that you have both Photoshop and Lightroom. Here's one way to do it: In Photoshop, open up your image, and go to Image > Duplicate. This will duplicate your original image. Then go to Image > Image Size and you'll get a window that will allow you to resize your duplicate image either by changing the pixels or by changing the Pixel Dimensions or File Size. Make sure the 3 boxes are checked at the bottom: Scale Syles, Constrain Proportions, and Resample Image. If you're emailing photos to friends or family, I might make the photo 5 x 7 inches or so. Otherwise, if you're submitting online, check to see what pixel size is required. Hope this helps!

Resizing to about 5x7
The image I opened had a little different perspective than 5x7, but it is the same idea. The only difference is the width of a true 5x7 will be 700 pixels, and the document size will be 7 inches.you can read about resampling options direct from Adobe, here: http://helpx.adobe.com/photoshop/using/resizing-image.html

Corky,Sorry you found my response confusing. What I tried to say is: sometimes resampling is the only thing you can do. I have been an expert in the field for 20 years... If someone with a similar amount of experience is telling you not to resample, I am guessing that they were referring to the original. Don't resample an original, resample a copy/duplicate, as Lynne says. Do you have a source that you got the info about *not* resampling from? You will have choices for resampling type. Bicubic Sharper will probably be your best choice. Also, a 5x7 on a computer is going vary depending on the resolution of the monitor that it is viewed on. The best way to control this is with pixels. You will want to have about 500 x 700 pixels @ 100ppi. I'll upload a screen of what the resize screen should look like. I hope that helps! Sometimes the questions you might think are simple have a lot of twists and possibilities. Richard

Oh, and about the filter... polarizing or neutral density would be what Corky seems to be mentioning. Polarizing is more beneficial when shooting around water, glass and other highly reflective surfaces. Believe it or not I fly against the grain with the UV filters, as I don't use them -- it is another piece of glass to add to the pile. For safety I use a secure wrist or hand strap. Richard

Thanks Richard, that clears things up for me. I think it was in a tutorial video from Michael the Maven that he said not to resample. That's what I've always done for web or email. I usually just go in, set it to percent and do 25 to 35 percent of the size and it's always worked great. Of course I never do it to the original. I was relieved when you said that resampling is sometimes the only choice. Thanks!

Glad that helped. Did look through a few of Michael the Mavens things, and do see references to resizing in the context of video (which he seems ok with), but not images for email. Of course I didn't read the whole thing and didn't watch every video... I'd be curious as to his reasoning if he does state that, however, because I can't think of a reason to support "never resizing" unless it is to originals. Advice is no good unless there are solid reasons behind it. On the other hand, I did see some errors in Michaels blogs, like where he says "browsers tend to desaturate images". That is actually a color management issue, and a common mistake: he likely works in AdobeRGB color space (not a bad choice) and fails to convert to sRGB before uploading (which leads to desaturation). Browsers tend to ignore profiles... so you'll get desaturated results with the wrong workflow. My point: take any individual's advice with a grain of salt... the consensus is usually closer to the truth -- and if your personal experience proves otherwise, do what's best for you. Like my mention of not using UV filters... it works for me not to, and the reasoning behind using UV filters is generally valid for other people. My parting from the consensus had to do with a fluke accident in which my UV filter seems to have damaged a lens... I think lens hood, a cap, and hand-strap works well... for me. Richard
