Now, I'm always a fan of the sunstars, so when I can, I usually include them. If you want to get a nice sunstar all you have to do is shoot at a lower aperture, like F/16 or lower. Then once you've got your aperture selected, wait for the sun to just touch the horizon. Once it first hits the horizon you only have a matter of a couple of minutes before the ability to get that sunstar is gone.
In the old days, I used to take bracketed photos of a scene like this. What I mean is, I would take a photo that exposes for the foreground, then I would take a photo that exposes for the background, then I would blend them together in Photoshop. This is the same effect you would get if you were using a Graduated Neutral Density Filter in the field.
Over the last year and a half or so I've had with my Sony A7R, I began to notice that I could just take one shot and the sensor in that camera captures so much detail, that I can pull all of the detail I need out of one picture.
I processed this image in Lightroom then jumped into On1's Perfect Effects to finish it off. Images like this benefit greatly from the "Golden Hour Enhancer" plugin found in On1's Perfect Effect Suite. After applying that preset, I added another one of their presets for a vignette, "Big Softy". "Big Softy" is by far my favorite preset for a vignette, however it was a little too strong for my taste on this image. That's ok though, because I have the ability to dial down the opacity of each preset...just like you would do in Photoshop.
The image was made with my Sony A7R, LA-EA4 Lens Adapter and Tamron 24-70mm Lens.
