I would recommend using at least 2 strobes if you can use 3 ( Paul C buff are great strobes)

Simple winner setup

1. Two strobes on the side behind two diffusers(I am using Savage Translum Medium-Weight Grade).

2. Surface - I am using an Acrylic Sheet.

3. Background, I am using Savage Seamless Background Paper I make sure the last strobe point to the background of course.

4. Never put the product too close to the back ( background paper ) because you will have a light spill that creates a nasty halo around the product.

5. You can use either 50mm or macro all depends on the shots you are taking. From what you posted 50mm is fine.

6.You have many ghost mannequin out there that can make the shirts/ pants loos great! make sure you steam them before to remove any wrinkles.

7. Focus stacking when needed. very important to create a fully sharp image.

Camera settings: If you have 3 strobes you can go low on the ISO which will remove ALL noise (snow) like issues. I would recommend also under ISO200 / F10-F12 / Shutter 1/200 or 1/100. don't go over 1/250 because the flash is not fast enough for the camera and you will have a nasty black line in the image.

Good luck!
