As I understand it, most all the open source software is based on dcraw - so they're going to have similar capabilities with different interfaces and some extensions.
and with similar limitations.
what limitations are these?
We all know that. But nospam just wants an argument...
And if "take a quick look at things" doesn't mean literally just viewing, but involves something else. It could be for generation of an histogram or any other kind of data analysis, which in fact requires the image file rather than a visual display of the image.sidray carternospam
In the past, I've found dcraw useful to get a quick look at things by extracting the jpeg thumbnail (dcraw -e).
once again, more work than needed. on a mac, there's no need to run anything (especially using a command line). a simple tap of the space bar gives a quick look of nearly any file (photos, pdfs, spreadsheets, zip files and much more), which is why it's called quick look.
So how does quick look know which file you would like to see?
DCRAW is commonly used for comparisons between camera models to provide essentially the same processing to disparate raw sensor data provided by different camera models and even across manufacturers.
For those like nospam who cannot envision any use not provided by someone else for him, there is no need for programs like DCRAW. For those who work out of that box DCRAW is a very useful tool.
