I don't usually do any landscape photography, more portraits than anything else, but here's a capture I got of a field near where I live. The clouds are what inspired me to take this shot. It's had a few custom Lightroom presets applied as well as some tweaking until I was happy. I have been asked if it's an HDR but it's not, it's just a single exposure.
You can see why people have asked the question though, it does look as though all the detail of the scene has been squashed into a couple stops of dynamic range. For my taste its a little over done, but if you like it then thats all that matters.
