How H? By doing frequently.
I did school photos recently. Charged $5 per portrait, $5 per class shot. That kept the wife happy a while.
Wedding 2 weeks ago, another $500.
3 x Model portfolio shoots last week, $100 each. Got 2 more this weekend.
Cafe advertising late December - $250
Daily online sales is not much, but enough. I pay $79 per year for an offshore website (hosted in Israel!), so doesn't take much to cover it
I go for the reportage style more so than the staged photos that I try vehemently to avoid. That does not always pan out.
