how was your setup?
On the left machine on the white background, at the bottom I see a lot of washed out edges as compared to the image on the messy background.
The 2nd one may be a bit over exposed. Maybe bring the Blacks down a bit too. Some of the buttons on the back are not legible. And I may see some flare spots on the image - maybe over the blue label.
But for a catalog page that needs consistent white/blown out backgrounds it's pretty good. people aren't going to scan for little quirks. As long as all the buttons/writings, etc are clearly defined with good Depth Of Field, and the edges are too blown out you're doing good.
I don't do much product items though so hopefully someone with more experience will chime in.
