No one likes an unbalanced Photographer!
Or mores to the point an unbalanced portfolio.
It makes little to no sense to have a 30 page portfolio containing 27 pages of colour studio portraits and 3 B&W Landscape shots of the Norfolk Broads.
I'm sure they look beautiful but you're only pleasing your Mum with this and you're most likely confusing the hell out of your clients.
Go and have a quick look at your folio now. If the above applies to you then correct this madness immediately.
Trust me, it's for your own good.
