Filters: Color and Contrast

For these I took a simple photo that had some color and shadow. The overall goal was to enhance the color and contrast of the picture, specifically, in the shadows reflected on the wall. I also wanted to enhance the plastic, cartoony feel of the bottles.

With this goal in mind I tried about 10 different filters with variations of each one. I picked the best 3 from those. While I did keep my original goal in mind for each, I also did what I always have done when using filters on my photos, which is basically pick what looks good. I don't know how to define it much more than that. The 3 filters I ended up using for my orginal goal/them are Dark Strokes, Sumi-e and Accented Edges. The Glowing Edges one I threw in as an abstract departure. Its been done I know, but I've always liked it, and I like how it emphasizes the bottles and their colors. I recommend clicking to enlarge each one to get the best feel for its effect.

Original Photo

 Accented Edges Filter

-enhances the texture of the wall, shape and plastic feel of the bottles. enchances color, shadows and spots of light on the wall-


Dark Strokes Filter 
-high contrast with this one, it really darkens the shadows and turns up the color on the wall-


Sumi-e Filter 
-another high contrast, similar to the Dark Strokes but less is lost in the shadows, more clarity-

Glowing Edges Filter  
-gives an abstract feel and highlights the colors and outlines of the bottles, bringing them into the foreground-

Filters: Smart Sharpen and Ink Outlines

I took this photo at school a couple weeks ago. Before I knew PS, I would have chucked it into the burn pile. For the filters project, I decided to bring it back from the dead, and use some filters in process. My goal was to make this picture look like what I saw when I was taking it. In other words, how I imagined the picture would look when I took it. Here's a general outline of what I did.  

Camera Raw
Raised temperature a little
Adjusted exposure 
Adjusted brightness and contrast

Photoshop
Levels - Raised low and mid levels
Applied Smart Sharpen Filter - Remove: Lens Blur Amt. 200% Radius: 2 pixels
Faded Smart Sharpen Filter: Luminosity
Adjustments: Selective Color - adjusted reds, greens. 
Adjustments: Selective Color - neutrals - raised yellow (with only totem pole selected)
Hue/Saturation Adjustments

Applied Ink Outlines Filter
Hue/Saturation Adjustments

I was able to sort the colors out fairly easily; I feel like I'm getting better at that. The main trouble I had in this photo was contrast. The original is washed out and flat.  I turned up contrast in adjustments but it wasn’t enough. The other problem I had was all the white snow. I needed a way to get contrast and definition around the edges of the snow, and to make the totem pole stand out from the background. The Smart Sharpen filter helped with this but it wasn’t enough. I wanted the final image to be a bit stylized and to crank up the contrast at the same time. To accomplish this I ended up using the Ink Outlines filter. It added the contrast I needed and lightly outlined the snow areas, plus gave the totem the look I was going for. This end result (rightmost picture) is very close to how I imagined the shot when I took it.    

One problem I ran into was losing some details of the Ink Outlines Filter when I reduced the image for the web. (I changed it from 300 dpi to 72.) I ended up going back and reducing the image without changing dpi. Hopefully the conversion that takes place during upload will be more kind. Be sure to click on the image to enlarge it and get the full view. Added note: alas the details didn't quite come through after the upload. I still think the results/improvements are visible enough. On a widescreen you can view all 3 at once. Non=widscreeners will have to scroll, apologies.
