I hope you received some photo related gifts over the holiday. If you did not, you may want to consider a present for yourself: a subscription to Photoshop Elements Techniques.
A subscription provides you with a bimonthly newsletter and online access to a blog & tutorials along with practice files. The January/February 2015 issue includes excellent articles on using layer blending modes, sharpening photos in both Camera Raw and Elements Editor, following a basic workflow to enhance pictures, directing the viewer's attention in your image and photographing waterfalls.
You can learn more about this site at www.photoshopelementsuser.com. If you recently purchased a copy of Elements, you would have received a card introducing this web site.
