Hey ! These are better than hobbyist ! There are a bunch of online resources like rggedu and creative live that I would check out but honestly you might pick up a thing or two from them but nothing you aren ' t going to learn on your own after multiple shoots . I am professional food photographer and I ' ve researched the hell out of resources and nothing has replaced repetition and personal critique as my best resource for growth . Though do check out Rob Grimm ! He ' s pretty commercial but very versatile and educated t u t o r i a l s p r o d u c t s f o odphotographywithrobgrimm <| sep |> You need to change velocity to get an orbital capture , you can either use engines or aero brake off of the atmosphere if it has one . Having to reduce speed at the destination isn ' t an EMdrive problem , it ' s just something you have to do . It ' d be possible to use a conventional engine to make the retrograde burn faster , but it could very easily not be worth it . You ' d have to run the numbers to see if the extra mass for the fuel and engine would actually save time , as all that mass would especially slow the EMdrive acceleration burn .
