Tim, interesting comment Tim re Lightroom. What do you think of the new LR3? I've never used LR but thinking of dropping DPP and PSE and just using LR3. What you've said is quite persuasive! Thanks
Brain dump alert- apologies for random structure to the following :
I stopped using DPP when Lightroom 1 was released. It's not that I was ever unhappy with the IQ produced by DPP but the software was so limited in some areas - no workflow features at all, not even a simple straightening tool, highlight recovery very poor. It's caught up a tiny amount in terms of features, but does restrict one's ability to finesse an image. There's no local adjustment brush, no fine tuning of sharpening, no graduated adjustment filter, no perspective adjustment control. Lightroom 2 introduced some of those things and Lightroom 3 took them further, with refinements to the demosaicing algorithms and better noise control.
Lightroom lets you easily compare two images in detail, or a whole bunch of images, although not zoomed in. Selecting the best images from a large shoot is so much easier than with DPP and you have so many more ways to classify/categorise/keyword images. You can pull out all the images you took with a particular body, or lens, or combination, and there's lots of other metadata you can filter by. It has immense power to cut and dice your images, and walks all over DPP for fine tuning. There are also some really nifty presets available for Lightroom, which allow you to do amazing things with a single click.
I've tried Photoshop and I hate it. I don't have the patience for it, and I've tried learning it but it just won't stick. Lightroom is fast and powerful. It has features I don't even use, like generating an HTML or flash website, and facilities for setting up printing well beyond DPP, but they will only add further to the value for some people.
You want to remove or add a vignette, no problem. Ditto a watermark. It doesn't have the pixel editing power of Photoshop, and you can't cut and paste images together, but it is a great tool for editing PHOTOGRAPHS. If you want to do graphic art and pixel level edits then look elsewhere.
Another strong point for Lightroom (as with DPP) - non destructive editing, even of JPEGs. Unlike Potoshop you don't have to fuss around deciding which format to save your edits in, or worrying about converting from 16 bit to 8 bit before you save as a JPEG. It is extremely friendly and quick, and pretty much idiot proof (in so far as you can't screw up your original files). You never have to remember to save your edits, because they are saved as you go, and you can revert back to any stage in your editing, including the original file, whenever you like. You can creat virtual copies without actually duplicating entire files, so you could for example have a colour and black and white verion of the same image, or a subtle version and an extreme one. You can have as many virtual copies as you like for each image.
I'm sure the list goes on and on.
Regarding the need or not to edit a file, I find the Lightroom defaults to be a great starting point, but you can create your own default settings for each camera body, or even each body and ISO combination, and these will be applied when you import, saving you the need to edit further. There are differnet camera profiles provided, so you can simulate Canon's standard picture style, or neutral, or landscape etc..
You can also develop your own presets that can be saved and applied whenever you like.
Here are just a couple of examples of the power of Lightroom, with remarkably litle effort involved. Let's see DPP do this....
A bit of a crop and vignette would finish this off, but as a one click edit this is a good start :
And another. This is a JPEG from my point and shoot :
