There is a similar bridge near me that I've been practicing on. So what is everyone else using for software to make there versions? I used Photomatix 4.
Simply take your shots both over and underexposed by 1 EV. Then put each shot in a layer in photoshop and erase the parts you dont want in each layer. Flatten and thats it. A bit of unsharp mask and its even better.
Ya I dont know why photo sites limit filesize or at the least file dimensions. Going through places like Photobucket and Tinypic always seems to degrade the image in one way or another. Color shift or soft focus seems to be common.
