FUN WITH FILTERS | WIDE ANGLE FILTER

Hello Everyone! This is Jenn aka jk703, here to start a new series with you on the PRD blog! This is a different way to use Filters that we have available to us. Filters are simply ways to add effects to your image. Each one is particular, and usually allows you some freedom on how little or much you use the filter. You can try them out on photos, different patterns, and see what you get! We are going to show it off slowly. This way you can learn a little more, at a slower pace, and actually give the filters a try.

For my example images, I used Mirjam's Blue Skies papers.

For today's Filters, I'm using the blue and white striped paper. We are going to focus on the wide angle filter. Most of the time, this filter is used to correct photos. We are going to use it the opposite way, and see what it can do creatively to papers. Here is a sample paper, in it's original pattern:


I have a new project open, and I brought in the #4 paper. Once it was open, I double clicked on the layer in the Layers Pallette. This will allow the Background to have changes made, and will renames itself Layer 0.


First, under Filter, you will choose Adaptive Wide Angle:


Then you will get a pop up screen that really brings you to the Filter Gallery. When it does pop up, in the right top there is a drop down. You will choose the Fisheye correction. Fisheye
basically corrects extreme curvature caused by a fisheye lens on a camera.


The next area are the Scale, Focal Length and Crop Factor.

Scale is a value that you can choose with the slider. It is used minimize any blank areas that might appear after applying the filter. So, for mine, I bring the scale up to approximately 115%, which allows the paper to create the effect, but then I don't lose any of the papers pattern when the filter causes the curves.

Focal Length is a value that may be automatically filled in if the lens information is detected in the photograph. If not, you can just use the slider, and you will adjust as you see the image on the left change.

Crop Factor will come into play when the final image is cropped. You will use this value together with the scale value to compensate for any blank areas that are created while applying the filter.

Here are the figures that I ended up with:


After pressing ok, this is what my paper looked like. I think it looks pretty cool!


Now, starting with a fresh paper, you can also do the Perspective correction from the drop down. Here are my numbers and the paper outcome. Opposite of the Fisheye!




Pretty interesting to see what happens to papers when using the filters! Filter Fun!
