I do not know if it is the camera you use or the weather is so clear there, but the picures you post are some of the sharpest and most clear of all the ones on the mountain pages.
Thanks, 22arnie! With ACDSee program i improved contrast, exposure and sharpness of original photo. But, photo is still natural as was weather on that day. When you submit some photo, you must improve contrast, exposure, sharpness and color before uploading.
