Right I have managed to sort something out here now ....

Yes the Adobe converter does indeed work , I was trying to load files from an open folder , it appears it will only work using a unopened folder , load the folder itself .

Now I have done a few to see what happens , at first it halved my file size once converted , that can't be good can it ?? Think the use lossy was ticked at that stage .
Have it set to not be lossy now and that gave me an almost equal file size to the original RAW ??
Managed to set it to keep pixel count to give me the same dimensions .

Now the Exif tells me its uncompressed . Res is 96 dpi ?? Is that right and ok ?? As was reading about printing and using 300 dpi ?? I know this can be set when exporting from Lightroom so is the 96 dpi an issue at this stage ?? No need to explain about the rules of dpi and printing as will be a long while until I have some worth a print , I just need to know if this is ok at this stage please ?? Oh and it says Bit depth is 24 ??

Yep - that is why one of my suggestions was that you might not be 'feeding it quite right' - I remember having issues along those lines on the few occasions I needed to use it.

I think, when converting your RAW to DNG, you want lossless, which I think is the alternative to lossy...

That sounds good.

That sounds good. Stay with that until you make a final JPEG from it.

I suspect you are referring to ppi (pixels per inch), which is a term for defining the resolution of a digital image: pixels per inch. The term dpi refers to dots per inch, and refers to print-heads. The whole ppi/dpi aspect only comes into it when you are printing. While you are working on the PC in Lightroom, creating images for emailing, website display, etc, all you need to know is how many pixels wide, by how many pixels high. The monitor you are viewing it on will set the viewing resolution in pixels per inch. A 4K monitor might be 180 ppi; an iPad, 118 ppi, a decent TFT around 100 ppi, and a crappy old one about 72 ppi.

When you come to printing, around 360 ppi is a good resolution, though anything from 250-300 ppi is usually OK. A lot depends on the size. If you are printing a huge 36-inch poster, you naturally stand further away from it to view it, so as low as 150 ppi might be fine. If you are printing a 7 x 5 inch photo, you will naturally hold it close to your face, so 360 ppi might be required to give a good image. The two parameters kind of go hand-in-hand, if you get my drift.

I suspect the person writing the Exif programme didn't know their dpi from their ppi...

Got it, thanks, and no probs - nice to see a question on the subject of taking photographs, instead of the usual armchair gear-wars nonsense...

My first camera that shot RAW files was a Fuji F810...

I'm saying nothing.
