The oven is from Lisen, you can find it here, and the counter is from Buffsumm, but I have to ask you to look for it yourself since he has really a lot of creations and I don’t remember from which set I got it.
I have received many asks about this recently. No, I don’t use an HQ mod. I have tried Simsl3gacies’ HQ mod once but it made my game lag to the point where it’s just uncomfortable to play. I reckon I owe the good quality of pictures to my Photoshop actions and good ambient lighting…. mostly good lighting! I used the same action for several posts now, but I can’t always say that my pictures look great every time. About 80% of the outcome depends on how evenly and not too bright nor dark your pictures were from the start.
