All the pictures I've taken so far have been in jpg. What is the
converter and how does it work?
It sounds like you come from a strong film background... Film is fairly simple to use and inflexible... Digital is quite different, and because it is so flexible it can work in a number of different ways for different people...
Exposure is quite critical.... It's similar to exposing slide film, but digital doesn't have the shoulders on the curve that film has, so it is essential that you avoid blowing the highlights (i.e. don't overexpose)... At the same time, you need the bulk of the histgram either in the middle or to the right, to get the best dynamic range....

There are many ways of using the camera and software settings, including many pieces of software, but I'd consider four main approaches first....
1) JPG - the S2 gives class-leading out of the camera JPGs... If you want the simplest possible approach, with the smallest amount of post-processing, then set the camera to the settings you require and just use the JPG output... Obviously, if you set the colour to ORG, then it will seem very muted and dull, so I would suggest setting everything to STD first, getting decent pictures and only then experimenting... For example, you might like a Velvia appearance, so might prefer setting the colour to high instead... Most people do not consider JPG as suitable for quality work, but (in Fine mode) it's really very good... Certainly 18" x 12" prints from JPGs can be perfectly acceptable... Some people even claim that much bigger enlargements are feasible... If you want the quickest workflow and minimal post processing, then this it it... Some pros only use JPG, as it gives perfectly acceptable quality and much smaller file sizes (4.5Mb)
2) Using RAW mode and the LE converter - With this approach, you use the very cut-down LE converter provided in the UK to process RAW images into 8-bit TIFFs... I've compared a number of images at 100%, and although I'm quite prepared to accept that the RAW versions may be better, I personally can't see any significant differences for smaller prints sizes... Quite often the images have to be blown up to 2-400% to show the differences....The Raw file is 12Mb and the resultant TIFF is about 35Mb, so we're talking near 50Mb storage per image... I can't really see that there are many benefits in this approach, personally...
3) Using RAW mode and buying the EX converter - I recently bought the EX converter from amazon (£96) and find it very flexible. It allows you to produce 16-bit files (which may be useful if you have a suitable imaging package) but are not a lot of use with lower end 8-bit packages... More importantly, if allows you to change most of the main camera settings (including tone/exposure etc) after the picture has actually been taken... To a slide film user, it's like magic

Consequently, if you want the highest possible quality plus the greatest flexibility then this is the way to do it... However, it means that each batch of pictures (or even each picture) has to be modified, before you even have a TIFF file to work on...
4) Using RAW mode and other converters - Adobe CS has a plug-in that handles S2 RAW files (supposedly excellent) and there are a number of other programs that can process RAW files with varying degrees of success... Some, like Bibble give you a better workflow than EX, but (IMHO) at the cost of some quality...
I would have thought a handheld meter reading is handy for most work > and absolutely essential for the studio.
I must admit, I can't see why a handheld meter shouldn't work... It's only a meter, after all, so I'd expect it to work in the same way as with film... However, the S2's meter isn't that bad, so if it's way out you could have a faulty sample... It's not that likely, though...
I shall send a few pictures next time.
That would be useful, certainly...
I used to be a firm 35mm slide user... From my limited tests in the six months that I've had the S2, I now consider the S2 to be so far ahead that I can't see a reason for using slides again... If you persevere, I'm sure that you will also be pleased...
