RAW format grey-scale issue

[itsatrapski]

Hey all,

I've recently discovered RAW format! I took a couple pictures of the same object, one in JPEG and one RAW, the latter of which ended up saving in a MRW format. I couldn't even open the MRW file in Photoshop. I opened up another JPEG image I had, saved it in RAW format, then opened up that RAW'd image. It appeared to be blurred together (stitched?) and in grey-scale.

Is there something I'm doing wrong? Or is this normal and I'm just being noobish?

Thanks,
-Alec

Well you can't save a jpeg as raw and expect it to be anything but a converted jpeg. A raw file is what the image sensor actually sees. When you shoot jpeg your camera captures raw data, does a conversion, throws away data it did not use and saves as a jpeg. When you capture raw you have all the "raw" data and can process it anyway you want. I don't know what MRW stands for but it is most likely the format your brand of camera uses to save its raw image. You whould have some software that came with the camera to open it. If not, you might want to google "MRW File format" and see what comes up.


I just did and it says "Minolta Dimage Raw Image File"
