i find landscape pictures difficult: the lighting must be absolutely spot on, which is determined by a number of factors you have no control over but must anticipate. your pretty much onto a winner for light early morning or evening, but the afternoon can be a nuisance.
the variegation of the layers of cloud must be bold for me, this will mean they are moving, shifting the light, if they break & coagulate constantly, giving the sun opportunity to break out. if a blue sky isn’t solid enough but washed with a milky patina mingled with light it makes for an ugliness i can’t abide & is difficult to work with. so i don’t always end up with what i feel is an aesthetically stimulating photo, regardless of whether the landscape has implicate beauty. unfortunately Korea gets a lot of humidity & on those days i pretty much throw my hands up in defeat. there just isn’t a good atmosphere to muggy, humid days. the most photogenic days for me are those days when the wind is swift & urges the cloud with its swiftness, the cloud tends to layer on these days & sometimes their tones will vary too & it just begs for being photographed.
