We had a photographic session at Venture in Knightsbridge and the photo's were amazing. We bought a voucher which gave us the session and a small picture - we thought that was good value - then we saw those amazing photo's we had to have some more. The service was and the product was very good. They are not cheap - nor do they pretend to be - there are lots of cheap photographers around - but I have not seen this quality before.
If you are interested we bought a voucher for £25 - we were called by our photographer to discuss what our interests were and how we wanted the session to go. We arrived and were welcomed - we had a good one hour session in a very well equiped Studio. The photographer got us and our family doing all sorts of things we did not dreamm of (moving around - different ways of "squeezing" together). We booked to come back and look at the photographs. These are projected onto a wall in a small room and were fantastic. The problem we had was deciding which not to buy.
Conclusion - if you want amazing photographs of you and your family you will not beat Venture at Knightsbridge. Do not go there and expect only to spend £25 - you will need nerves of steel not to buy more and will be kicking yourself if you cannot afford it. The photographer showing the pictures was not pushy - but the pictures and the range of frames made you want to buy. They are not cheap - but then again nothing that good could be cheap. We will treasure out photos' of our family on our wall for a long long time.
Hope you find this of use.
