This is an image I took on my first day in New Zealand about two years ago. As you can see from the colors it was autumn in the southern hemisphere. If I recall I was so happy to see all the fall colors that I quickly processed the photo and posted it a few hours later.
Now when I look back on the image http://www.justenoughfocus.com/autumn-new-zealand/) I realize my tastes have changed. That's a nice way of saying the other picture makes my eyes bleed. The colors of the original are amped up quite a bit and appear too bright and unrealistic.
And so as I was looking at some of my old photos the other day and I thought to myself, why don't I reprocess this? Since I have the original RAW files I did, only his time I used different tools and techniques I've acquired over the years.
This is a three image HDR that I originally combined in Photomatix Pro, this time in AuroraHDR Pro. Last time I wanted the colors to blast so I oversaturated them, this time I wanted it to be a little more realistic. I think both versions have their pros and cons, (I'm being kind again). The old image looks pretty good as a thumbnail or on a phone, this one looks better on a large screen or print.
Each image has its place, but as I continue to evolve as a photographer and artist my taste change and so do my techniques. This is just another example of that. I plan on reprocessing a few more from that trip, stay tuned.
