A few months ago I took a free course in framing and special effects from Jessica Sprague. One of the best things I learned was about the use of textures. Jessica shared some links for freebie textures on Flickr, but I have since found out about a wonderful blog from Rita at Coffeeshop. It is called Shadowhouse Creations and features his wonderful artwork, plus some free textures and brushes. It is well worth a visit. I downloaded some of the textures and started playing.
This is the photo I used - straight out of the camera, no adjustments.
This was with tone textures from Shadowhouse Creations - #3, soft light, opacity 50%
Then I added tone texture #4, soft light, opacity 100%
On this one I used the soft translucent tone #9, Shadowhouse Creations, color burn, opacity 75%
On this one, I used tone texture #10, again from Shadowhouse Creations, overlay, 100% then added his painterly effect texture, soft light, 75% opacity.
I love what these textures can do and how they enhance photos.
