A polarizer can make some reflections disappear or, if rotated 90 degrees, it can make the reflections stronger. In general, transparent materials, like window glass, water and even air, affect the polarization of reflections, but metallic reflectors do not. So, in answer to your questions: Depending on rotation of the filter, it can increase or decrease ...

I've used Cokin A, Cokin P, and Lee filter holders. There are issues with each of these that you will need to consider between price and what lenses it can work with. There are plenty of blog posts about the various merits of each. The first consideration would be to get a circular polarizer with threads (rather than a thin one that lacks front threads). ...

If you want to combine a polarizer and ND filters in the same exposure, you're probably better off going with Cokin's system. Their holder allows you to use square/rectangular ND or GND filters at the same time you are using a non-threaded circular polarizer that can be infinitely rotated. The Cokin system comes in at least three sizes: A (for amateur?), P ...

Ultimately, you're going to break the bank if you head down this path. Lee is superb, not cheap. they have square polarizers that might be useful. If you're going to go into a square filter you're likely talking about a full commitment. I think I've seen one holder that allows a round filter to be added, but I worry about vignetting at wide angles. The ...

My guess is that this is a composite of two or more pictures. One was taken at night when the lights were on. This is where the artificial lights in the picture come from. Another exposure was taken when there was more daylight. This is where the light sky and illumination of large flat areas that weren't bathed in artificial light came from. I disagree ...

I'd say it's just the light pollution hitting the fog and smoke in the air. Exagerated by the long exposure needed to get the buildings that bright. But you might want to ask the artist himself: http://caudroy.fr/gallery-category/projects/#hong-kong

it's definitely the filter, even my 30 dollar hoya does this in low light, it really screwed up some pics before.

The high pass filter is not something that can generate a mask of the skin tones within an image, hence why you wouldn't see much success trying to use it for this purpose. One possible solution would be to use PhotoShops Select → Color Range... option. I think in CS6 onwards there's an option in the Select drop-down box of "Skin Tones" This can be used ...

Name Gradient color wash/gradient color overlay/gradient tint Bonus The video appears to be a combination of applying a tint to the video, a little blurring and some time remapping, possibly using a plugin like Twixtor. Filming at 60fps or higher would help facilitate the slow motion/time remapping. Similar speed effects could be accomplished natively in a ...
