Also think these are not competition images and probably just done to illustrate the article so the odd help here and things like that should not be focused on too much as sure you'd avoid having that if he intended to print them.. they still illustrate what he is trying to say to people having a read of the article rather than critiquing every little but of the frame
I like the article...
Tbh I hat overdone HDR. In my opinion HDR is a great tool to achieve a similar effect to clever use of filters or on scenes where shapes required make it impossible to use filters.
To me a great HDR should look very natural, should replicate what the eye would see and shouldn't be obviously HDR but could be mistaken for a good photo taken with filters.
Altought this article also draws attention to certain features and equipment it doesn't distract from the goal of highlighting just how good HDR can look and show a lot of people who think HDR is meant to look fake and synthetic that it doesn't have to be like this.
