Sometimes you just want to go back and rewrite history. Your older work feels immature and lacking.
If you feel like that, it's a good sign that there's been progress in what you do, because you are probably seeing issues in the work that you didn't see at the time you made them.
I've just had the uncomfortable task of going back over my older Bolivia work choosing images for inclusion in my forthcoming book 'Altiplano'. I think it's encouraging to note that I am uncomfortable with the older work, as I do believe there has been an improvement in my visual awareness, and hopefully editing skills.
There are maybe a hand-full of the 63 images that I intend to include in the book, that really need to be tuned a lot for one basic reason: way back when I started out, I didn't really know how to utilise the complete dynamic range of the print.
I think that review is healthy. But going over your older work endlessly trying to make it perfect isn't. Still, there are times when dusting off older work does give you the chance to reconsider.... but I often feel if the image is well known and much loved, it's best to leave it alone.
Let's see where my book preparation takes me......
