I've been out here (Sequoia and Yosemite) going on 3 days now with 2 full days left. WOW there is a LOT of hiking to do!! I have been to countless National Parks, and this is quite unique so far to me - they REALLY don't like roads here. I'm getting some great shots though. Unfortunately so far all the weather has been perfectly clear, or just flat haze. I'm about to crash and head back out at 5:30am to try for some nice sunrise shots, and HOPE for a bit of cloudwork.
I did make one big blunder so far...I made some good exposures on full manual, and forgot to totally reset for the next location. I didn't realize until I was all the way back to the car from the next location, that the lens was still on manual focus from the last location. I won't know until I get home how good or bad it came out. DERRRR!!
To anyone coming out here for the first time - bring VERY comfy hiking gear, pack LIGHT, and bring a flashlight if you are going to shoot anywhere near sunset. I just did an hour hike in darkness. The only thing I had was the dim light from my camera phone's LED, and it switched off every 30 seconds untill I selected it again in the phone.
Every day I have been dumping equipment from my Expedition 7 backpack (awesome BTW). I'm up to about 1 1/2 hours before I start feeling the weight. Tomorow it's just going to be memory/batteries, 2 lenses, one body and filters.
Off to bed, alarm will be going off way too soon.
