I use two software programmes for fiddling with my photos, PaintShop Pro 7 and PhotoSuite 5. Whilst PhotoSuite is not very sophisticated it does have its uses, particularly in controlling the printing side.
PhotoSuite doesn't recognise RAW, so I am going to convert the photos I take in SHQ to TIFF for safe keeping.
However, if I convert the JPEG file of 4.5MB in PaintShop, the file becomes 11.8MB, and PhotoSuite doesn't recognise it. If I convert the same JPEG file in PhotoSuite it becomes 20.2MB and PaintShop does recognise that OK.
Now, I ask myself, why should the same apparent action produce two different results, and is there really any difference in the resulting TIFF file other than sheer size.
It is clear from my messing about, (I refuse to call it 'investigation'), that I will have to convert in PhotoSuite , (I'm not short of storage space), but I do find it interesting and a few clues may help my poor old brain to comprehend what is going on!
Gongoozler. That makes interesting reading. Seems that not all programmes which appear to do the same thing, in this case convert graphic files, are equal! Also, if I have read it aright,(and I might not have) there appears to be some compression involved which I thought wasn't the case with TIFF.
Klof Ron, Stuartli and €dstowe, thank you for the conversion programmes. I'll have to look at them and see if I can fathom out how they work.
The Reasoft programme looks as though it is not free, but it may be easier to follow. I've had a go trying to use the other two and so far I've not managed a conversion. Nil Desperantum - I'll give 'em another go.
