As a photographer, sometimes we will get hired to do a shoot 1 or 2 days before the shoot. Sometimes we even come on set, and we don't know what the model(s) look like or where the location will be. This is something that happens occasionally, and you have to be ready for it! 

When this situation comes, remember all the techniques you already know, and try to apply the technique that compliments the designer's designs, the location, model and vibe. Make sure you show the designer the photos you take, to make sure they are happy with the style and you know that you are on the right direction. 

I find it weird how some photographers don't ever show the model or client the photos they are taking. I think it's very important to show the model how they are doing, giving them peeks of the angle you are shooting them in. Showing the client how the products are shooting, is VERY important, because you may think you are doing a great creative shoot, but if it's not complimenting the products you are trying to sell, then you are not shooting for the client. 

This shoot that I did in New York, with designer Estee Mila Jewelry, was curated through MITH Magazine, and I had little knowledge of the direction I had to do for the shoot. I was booked 2 days before the shoot. I wasn't given any mood board or reference image, so when I got on set, I had to feel out the vibe and talk to the designer about what she likes. She was adamant about how she liked the blur background and how she wanted it very focus on the face and designs. Shooting in Central park also helped me shoot more towards a softer lighter style. It ended up being a GREAT shoot and most importantly, the designer was extremely happy with the final photos!
