STYLE
I'm using a monoline style, so that the logo looks youthful, unique, yet simple at the same time. The monoline style is also used to give a clean, minimalistic design, which is apparent in most of high-end logo.
The heart shape could be used as accent in all future designs you might need.
COLOR
The logo is very versatile, so it could use almost any color without a hassle. Here I'm using the pinks and greens, as suggested in the brief.
SYMBOLISM
The hand represents service, which is very personal looking because I captured the photo reference myself.
The heart represents a special love, and in this case, wedding. The circle represents camera.
So, the overall concept is, the hand (service) that you provide will help to capture the special love.
FONT
The typefont used is free for commercial use, therefore there's no need to buy another license.
