There are a number of good threads on this topic, mostly from the last 3 months ( seem to be having problems at this end listing them all - but will try again later ) Try, for example, click here
Extra storage for most cameras on one type of card or another, most of which have fallen in orice, quite dramatically over the last 6 months. In general , only cheap cameras have no card storage facility and tend to rely on the batteries and built-in chip - change the batteries and you lose your pics.
Again, in general, the higher the resolution ( I presume you man Mp ? ) the more scope/flexibility you'll have - lots of 'medium' quality shots or a few at 'high' quality that can be enlarged, cropped etc.
Most will supply a software package for album storage and simple manipulation, believe me you can so easily get to the stage of loading too many ( offers on mag covers, trials etc.)
As for the 'best' software, time after time the mags will review and compare the popular ones, and the one which tends to receive all the awards is Photoshop Elements -- stand back ! others have their favourites ! Yse, you'll have to 'shell out' for that extra, but quality usually comes at a price, and at least you won't have the expense of processing at the local chemists/corner shop where you have no control over the quality of the end result.
Finally, my advice for what it?s worth at this stage is : a) decide what you want it for and is there a chance that you might want to develop it ( photography ) as a hobby if you get hooked ? B)stake out your budget figure, and don't go over it by more than 10% ii) listen to all the experts in the pub, read all the reports, iii) narrow it down to 2 or 3 models WITH THE HIGHEST Mp possible for the price and from the recognised camera manufacturers ( Canon, Olympus etc etc - they know how to make lenses, rather than electric cookers ) iv ) go and look at them at Jessops - they tend to be smaller than you might think v) when you 've ordered / received it, DON'T look at another photo advert for at least 2 years, cos next week will bring that bargain ..... and you might just be upset vi ) go and use it, and have fun, experiment to your heart's content - instant results can be deleted at no cost, if necessary vii) check out click here - from Links above, usually ! - you'll be amazed what's available and for free !
Finally, everybody and his dog will tell you what they've bought and will try to convince you that 'it's the best camera deal on the market' Whilst some are valid, but others are still trying to convince themselves.
Finally, enjoy the search and then the final result !
Hope this helps
