Yes, a brand is not a issue, because all DSLR basically deliver what you need. Just pick the brand nikon/Canon ( the most popular , avoid those not popular because you will hard ot find the second hand gear , resell value , also you can borrow and interchange with your friends. ) My advise , you go for the brand where your friends and member have, for acmatual easy to learn form each other .
basically : Nikon - photo more bring yellow color ( setting can be adjust , or using software , popular for white guys becasue will bring up skin color not that white )
Canon - photo bringing blue color popular for asian because our skin are yellow and little dark , will bring out more white color of skin ,
I am a heavy user of DSRL , I am a wedding photographer for wedding for the pass 6 years . after going with your experience, all the brand you use delivery the almost same result, color? we do with software ( now a days )
