I purchased this box set on recomendation from a professional photographer who refered to it as his 'bible' .
I wish that I had bought this when I first got my DSLR rather than spending money on other books that were no way as near as usefull as this.
It's not split into detailed chapers on aperture, iso etc , it's more like each page is a 'tip' that points you in the right direction, under headins of 'how to take great portraits' 'animals' 'Sports' .
If you already have grasp of basic DSLR operation, this realy will improve your photography. You may not like his sense of humour but I found him light hearted and I felt that I didn't get 'bogged down' with the tech side. I'ts definately shown me what to buy next in terms of equiptment, i.e don't spend a lot on these 'gimmicky' filters, get yourself a few staple filters and an off camera flash and you will be doing great. Since it is split into tips, you may not take all the info in at once, but a good idea is to 'dog ear'/bookmark the pages you think are usefull for future reference.
Be warned, the books are almost magazine quality in terms of print & binding - but mine will be so messed up from taking them out this does not bother me. Each book also contains a 'recipe' section at the back - so in other words, 'if you want to take a photo like this, then do this....' which is a great quick reference.
I look forward to reading more of Scott Kelby's books, yes, he does churn the books out like there is no tomorow but I think they are great. Looking forward to his no nonsense, no jargon teachings of Photoshop in the future. This amazon Box set was purchased at £19.99 or thereabouts which is a bargain, as the RRP of each volume is about £12 and the box set retails in WHSmith etc. for arround £35.99. Hope this was usefull, and sorry for any typos!. :-)
