Tempest are very point and shoot, you have guidelines as to where lights need to be set up, backgrounds etc... you were not allowed to change the settings on the camera (which a few years ago was a Fujitsu bridge camera) no guidelines on if a child was wearing glasses how to adjust the lights to stop glare or how to position your subjects to stop it, poses had to be the same, no deviation from the Tempest plan, we stopped buying the kids school pictures and waited till they got home and I dug out my Sony and 50mm prime, I also did about 5 or 6 of their friends too in a mini group and solo shoot, when the oldest was leaving Primary, I ended up doing the prom shoot too, Max Spielmann have done really well from Tempest's misfortunes as well, they do know what they are doing and have their guys trained up well.
The other company are Venture, you get the shoot fairly cheap, sometimes from the likes of groupon, you go to the studio as a family, get the shots from a really friendly photographer, the kids jump around, he gets some amazing shots and then you go back a while later, ooh and aah at the amazing shots to be told you have to pay through the nose just for 6x4 pictures, they may be more professional than Tempest but they are still salesmen pretending to be photographers and they are pushy at that, one in Glasgow once told a friend that if they were not prepared to buy at that moment, that they can watch them get deleted on his mac as it wouldn't be worth his time keeping them, the friendly photographer turns into a not very friendly salesman.
