Sure...she has freckles...and that could arguably look find and/or great...but the dithering makes it look really 'blah.'

Overcompression is a serious pet-peeve of mine. Sunday I downloaded the "HD" 300 trailer, and it was so badly compressed that there were horrid artifacts all over the place. It was really distracting. HD my ass. Stupid thing was pretty huge, too, and compared to some of the other HD trailers (Harry Potter, for example) it was both larger and uglier.

For small or dark photos, PNG beats JPEG easily where compression is worthless and quality is demanding. In other cases, I'd go for TIFF, even if its support isn't as extensive as it should be, it has a better lossless compression for photos. RAW goes third, but support and file sizes might improve.
I'm a perfectionist so I hate that horrid tiles generated by JPEG artifacts, JPEG was made for the the 14k-28k baud modems in the early WWW years, now things have changed and size is not a priority when you have 500k+ bandwidth. JPEG should be dead. At least is dead for me.

Actually, in a sense,if you care about lossless versus lossy processing, you really should prefer raw formats to PNG or TIFF or JPEG. Since it's impossible to transform backwards from say TIFF to the corresponding RAW file, and different approaches to "processing" a given RAW file give vastly different end results (and also enable neat tricks such as converting a given RAW file to multiple (differently exposed) working files, then combining them suitable in Photoshop for high dynamic range photos.)

IMO, RAW is doing pretty well, but it may take some time for standardization and refining to be the best format for photography.

<chants> DNG! DNG! DNG!

As soon as the RAW files come off the cards and on to the
hard drive I use the Adobe DNG converter to change them
all to DNG format.
The compression is lossless and the files are about half the size.
Just about every current converter supports DNG and some
camera manufacuters are starting to use it as an optional RAW
format.

EDIT: Uh, DNG is Adobes' open standard for camera RAW files or 'Digital Negative'.

Nice, but all of that is way too fancy to be *my* film. [Razz]

I actually do know where my film is. It's on my dresser. And my spare camera battery is in my backpack, and my trusty camera is on my desk.

Since the only camera I own is also a part of my 2-year-old cellphone, I don't think I can participate in that conversation.

However, I will list a trio of my own: sorting algorithms.

The good: radix sort
the bad: bubble sort
the ugly: merge sort

(note- I know there are better algorithms out there, I've even looked at a few recently, but I had to implement these three for a project in Data Structures and make a graph of their run times, so I feel particularly qualified to analyze them [Razz] )

radix sort: Obtains n*lg(n) runtime but requires n extra storage space, which on most systems isn't too much of an issue but can become worrisome on systems with limited memory, large array sizes, or if you get a lot of paging faults. Particularly easy to implement, especially if you don't care too much about tweaking and use STL Queues for your buckets.

merge sort: in my implementation, merge sort obtained a better running time than radix sort (compared to bubble sort, they both appeared to have constant time), but just barely. It could be optimized for different data types, but my implementation required n extra storage (though there is an in-place version available). If for some reason you have a limited stack size, this could become an issue (and I mean a VERY limited stack. If a function can't recurse more than 31 times, you have some serious issues). Also a problem for large datasets.

bubble sort: sucks, plain and simple. n**2 running time, though it requires no additional storage. Quoth Knuth: "The bubble sort has nothing to recommend it, except a cool sounding name."
