I have been cleaning up all my pics and want to sort them but would like to convert them into a standard file format for easy post processing and access, currently they are all on Canon and Nikon raw file formats. what is the best option to place them in one file format but retain the raw data. I do have photoshop as an alternate program.

Afternoon wingman,
Well start by always keeping your Raw files, you never know!
Jpg format are pretty compact and maintain good quality, you loose a little on the colour side by only trained eyes will notice
Tiff format bigger file formats, Jpg is nothing else but a compressed and reprocessed Tiff!, but maintains the best pictures tones and characteristics.

I work mainly with Tiff formats and only use Jpg when quality is not the absolute priority in my work.

Your best choice is DNG.
This is opensource RAW, so anyone can write programs to work with them. Several makes of cameras even offer the option of shooting directly in this format now.

If you have Lightroom you can convert whole catalogs in one go (make sure you have enough space!), or one by one.
If you don't have Lightroom, well....



Then you simply download it. ;)

It's a beta, free of cost, but will only run till June 30, 2010. That should be enough time even for a slow computer.

Keep them in RAW. There is no alternate to RAW.

For myself, I stopped converting everthing to JPG. For real fast viewing of RAW files, use "Breeze Broser Pro"

And Lightroom for the mannage of your RAW files.

I keep all my images in the original RAW format. RAW to TIFF conversion apps keep getting better and better so it makes sense to keep your RAW files. With the software I use today I can get much better results from my 'old' RAW files compared to a couple of years ago.

Converting the RAW images to DNG would also work as DNG is also a (non-proprietary) RAW format.

Many thanks for all the help, the next question is what format is it best to convert scanned slides into.

Now this one is tricky!!! The biggest problem you'll face is not the format, most scanning software allows you to choose the format, but quality.
DNG and TIFF will give you heavy files and most of the times scanning slides requires some cleaning and colour regulating. The best I can say is try the various options and choose the one that gives you the best quality. I save in TIFF and DNG but then I have unlimited memory to work with and don't really look at that.
