why are you so adamant on warning/helping/educating newbies? i never understood the self destructing practice of photographers helping competition, which includes myself at times.

its like coca cola helping cott how to make cola

anyway, only those 3 tips?

1. doesnt make sense, i shoot holiday snaps with my DLSR
2. obviously
3. what is a ton of money? you need a good camera and quality lenses at the minimum. its a business, you need to invest to start out.

i didn't request anything. just wanted to understand your reasoning.

Nothing wrong with providing advice, but yours is probably a bit rudimentary, and debatable at best.

1. A decent shot of the pyramids, on your family trip to Egypt, although probably an oversaturated subject... is probably going to sell more than a picture of your sand-filled socks in the washing machine when you get back home.   

2. Obviously

3. What everyone else has said. Starting out in photography in general, I'd probably agree with that. Starting out in stock... you need a certain standard of quality. 

1.   Don�t shoot stock photos on your family vacation thus bring only your cell phone � your family will truly appreciate this!

This is similar to the advice I read in a book about making money from your photography. The author stated that when submitting images to publications, don't use photographs that you've taken on your holidays.

In any case, I disagree with this advice. Sorry to burst your bubble but not all photographs taken on holidays are snapshots. When I was on holiday on Kangaroo Island in South Australia in the 90s, I shot a pelican in flight over water with my Canon T70 35mm SLR and 75-300mm zoom. I made greeting cards out of the resulting image and sold them through a small art gallery (well, one of them was stolen as well.) Ive also sold a number of the cards at a market stall to tourists from passing cruise ships in addition to an 8 x 12 inch print. I also sold a framed 8 x 12 inch print of the very same image in an exhibition for $100. And recently, I sold a photo through Shutterstock that I took on a visit to Bora Bora with family (that had only been online for a couple of days.)

I think for number 3 it will vary by person. Easy fix, don't have a family then you can go anywhere and hang out wherever you want for as long as you want taking photos. I can see where keeping a family vacation somewhat separate from stock photo endevours would be a smart thing to do for your family.
