Polarizing filter – PRACTICAL GUIDE

Polarized light can be quite a headache for drivers, water sports lovers,  sunbathers, skiers, photographers… and it seems that almost each of us had to deal with the phenomena at some point. I am not gonna delve into the physics because there is a lot of good and available literature on the subject; instead I will get straight to the point.

On a sunny day at the beach I put my sunglasses on. Not blinded anymore, I can see the colors of the world again. White clouds against the dark blue sky, bright green trees, turquoise see. It is exactly how the polarizing filter works when placed on our lens. Light reflected from most of the flat surfaces prevents the matrix from saving a real color of the product or any other valuable details. The effect offered by the polarizing filter cannot be reached with the help of simple graphic manipulations, even in the Photoshop.

I take it that now you jump out of your chair in order to run to the nearest store selling photo equipment…

Ok, it’s time to take a closer look at our hero. It is not enough to simply fix it to the lens. The thing that distinguishes polarizing filter from other filters is the pivot collar. Observing the product through the viewfinder (in my case 2 pairs of glasses) I choose the setting that will reduce afterglows in the most efficient way and reveal the depth of real colors. Why anyone would like to get complaints saying: this color is different than the one on the photo?!

Dealing with individual packshots, effectiveness is 100%.

However, 360 photography poses an additional obstacle. Our product is moving, smooth surfaces change their location and thereby the polarized light is reflected at a different angle. Filter’s position set for the initial photo is not necessarily right for the whole presentation. One has to be patient and have a lot of understanding for the laws of physics ;).

According to the saying “first impressions are always the most important”, it is essential that this initial phase of the presentation is good and remembered by the recipient. The remaining photos and the product’s rotation serve to develop multidimensional picture. Light reflections [shimmers] – paradoxically – can help us because they add a bit of authenticity.

It is worth taking a note of the parameters of the presentations provided. With the help of the filter I can reduce some part of the light (polarized), therefore I need to extend the exposure time. Aperture remains high in order to maintain maximum depth of field, especially when photographing such a spatial object as glasses.
