Talking Rubbish!!!

Over the years I have heard some total crap talked about photography, much of it from people who should know better. Now I'm going to try and lay some of the much talked fallacies to rest once and for all.
Jpeg is as good as Raw. Wrong! jpeg has 256 tonal values per channel, Raw has over 4000, raw also has all the colour information, so if you get the settings wrong in raw you have a lot more chance of correcting it in post process.

Never use auto white balance. Why not? most of the time it does a better job the the user anyway and if you use raw (and you should) it doesn't really matter because you'll have ALL the options later when you edit.

Come off P mode (program/auto) if you want good photos. Again horses for courses, the trick with auto/program modes s to know when you NEED to come off them, switching to shutter or aperture priority doesn't make your pictures better is just alters the control you have over them (which is in program shift anyway)
Yesterday I listened to a photographer with 3 years experience tell a new guy that to make his pics lighter or darker he had to use aperture priority... Err it wont you know, the camera simply alters the shutter speed to suit keeping the exposure the same, you actually need to use exposure compensation to make them lighter or darker (or switch to manual).

Throw the kit lens away and get better glass. While there is a grain of truth in this one in as much as alway buy the best lens you can afford, the kit lens are actually a lot better than most people think, and in most cases stopped down a stop or two there's little to choose between the two.

Save all your photos as .DNG for archival use as you wont be able to open your old camera raw pics in the future. Not true, there's as much chance of being to open a DNG file (adobe digital negative) as there is opening your Canon/Nikon raw file, in fact I suspect the opposite is true, if adobe went bust support for DNG (which isn't that good now) would in all probability end, while lots of companies allow you to open your raw files.
It might be worth backing up with both if you have the space (just in case) but personally I don't.
