Jeez, this is turning into a forum of closed minds.
Because some of us - self included - worked with upside down images because we had to, seems to be no reason to pretend that we would choose to so do had we the choice of either on the same camera.
Take a peep at Albert Watson on location: one of the world's best snappers, and he delights in using a converting device to get life at the ground glass back to as near normal as possible...
I realised some time ago (aren't I quick!) that some here delight in taking a poke at FredBGG regardless of whatever he writes. It seems to me that there have been so many burned fingertips (or it that wallets?) that the whole MFD subject has become rather painful and anyone who brings it up in a less than positively confirming way has to be kicked into silence. Some would say, that's bullying; writing about a system failure is not.
Insofar as screens in daylight are concerned, when I first got my Samsung Galaxy Ace I thought it had broken;: the friggin' screen was black in the Mallorcan sunlight. Only when I went back indoors to make the call I couldn't make outside did I realise that the screen was perfectly functional (within its severe limitations), and that daylight is simply too bright for the system. I have seen any number of spoiled brats running around café patios here, banging these larger, confounded 'pads or tablets into people or onto tables - almost as bad as those with bloody plastic footballs! What are these idiotic parents thinking about? Buying love instead of giving it? Why does a nine-year-old need such a device?
As for taking pictures with my cellphone - I miss shots because I can't see the limits of the frame as often as I hit them. As you can imagine, this island crawls with tourists, and I see my own difficulty repeated time after time: folks stand there, arms stretched, squinting. And the irony? They probably think it's their fault they chop heads or feet... you can sell anything. Obviously.
Thank God my kids grew up in a reasonable era.
