Well the challenges get bigger as I move "up" to newer equipment. Newer lenses come with the need to figure out, when do I use each one?? I am currently in Gatlinburg, Tennessee and the colors are becoming beautiful as I type! My house overlooks several mountain ranges including Mount LeConte. The clouds have been releasing rain on and off for two days so I never know if I'll get rained on while trying to get a "shot". I am reading several photo magazines every night to tweak the day's pictures and make better decisions tommorrow. My favorite lens is now a Sigma 17-35mm 2.8-4 DG HSM wide angle. It has given me some great landscape pictures which I will be putting on my website amybecerraphotography.com.
