Hi Jason,
Very good work, much better than mine.
If I may.. :
#1. A bit too dark on the right side of Gianduja ganache. Maybe a fill card (or post process)
#2. That glass closed to plate is in wrong place (imho). Also, the slight angle I don't think it helps (even colours are not on your favor, green with brown.. both recesive colours..)
#3. Very good image of spiced pear, but with the same as first one ( slightly dark on right side). There is a big difference between pear and ice cream, from texture point of view, looks OoF. Even if is MasterChef creation, you have to put more texture on ice cream, this is why he/she is Chef and you photographer. Also, that slice of ginger... looks wired for me ( a very thin slice of a frog).
#4. Here you need a polarised filter, and focus stack ? I don't think that plate is helping also. Far objects from background might be cropped.
#5. I don't think is working like this, at least not for me, for two reasons. First is background, and second how big is that plate ? It is a Exotic fruits fest, give us "the whole fest". Also, there is a difference in luminosity between left and right side, and botom part of plate is too dark.
I don't know the exact conditions and gear from location, and how much time you have, but food photography is very tricky. You have to spent arround one hour (or more) for each plate, to try different compositions and light set ups.
Overall, I think you have to put a bit more light. It is a very slow process, and you really need to work those shots
For me, the first one is very close to "perfect", but all images are very good.
I hope you will take the filled part of glass, with my comments, and you will get astonishing pictures next time
Thanks for posting,
Leo
PS: speaking of devil....try to avoid empty glases, jars, any transparent recipients in your photos. Also put some colour/white tissue, try with or without ... and so on. Keep up with the good job. Leo
