Hi


any version of DPP installed on your computer from the very first is enough or if you have a CD with any version of DPP it is enough after you install it then you can go to canon usa, europe, uk or whatever and download the updates. DPP 3.8.1 is a huge upgrade and is free if you bought a Canon camera. But with DPP installed, Canon has made a huge and unadvertised upgrade to all its other softwaresitting in one of the sites above for you to download


I would like to say I have kept up to date with DPP but have not and let many updates pass by. I can only say that someone on this site triggered me to look again at DPP and there are algorithms in 3.8.1 that are superb for all Canon cameras to enjoy. And adobe has much catching up to do. But then you transfer to adobe to do the other stuff that is not covered by DPP. Soload from the card via Zoombrowser. Then go to DPP and in particular do noise reduction if you run high ISO then ignore Lightroom and go to CS4 (if you have it).


DPP 3.8.1 is new to me, I looked at this freebie when it was new and moved on. But in the interim there have been astonishing improvements. The algorithms are amazing and so much better that theearlier releases.


best wishes, Neil
