Load JPG on iPhone broken, when used with PNGs

Yes, most new cameras offer JPEG only. My old (2002) photo allowed TIFF, but today is either RAW or JPEG, with nothing in the middle.

I guess PNG is not used because of compressing algorithm that would use too much resources, but simple uncompressed lossless bitmaps in cheap cameras would be appreciated. But then again, most cheap cameras have crappy lenses, so image quality is awful even before it reaches digital sensor.

As JPEG is a lossy format, this is the reason I personally don't like it.

It is undeniably very popular, so it should be supported for that reason alone.

But for me, I use RAW on my camera for more consistent and high quality results, I use JPEG if I am low on space and don't care too much about the quality of the picture but want to save space on my media.

JPEG is ok on mobile phone cameras and such, especially when sending them over the mobile network, where file size is still important.

On my former job (casual games for PC) graphics for games were almost exclusively JPEG, sometimes even with bigger compression.
Casual players and portals are very sensitive to file size, so downloadable games have to be as small as possible but have all the eye candy. Since games are mostly 1024x768, just backgrounds for 30+ levels would use huge amounts of space if they werent JPEG.

OTOH, if you're making retro-remake/low-res pixel art game, it would be insane to use lossy image format.

It's just a matter of work strategy. Both lossy and lossless routes have sense in appropriate environment.

I'm sure it has something either to do with legal stuff, or just PNG encoding takes more processing than JPEG.   Considering the bulk of the processing power is capturing the image, converting it to a PNG while capture might require more than what the standard digital camera is built with.

Either that or they're just using the same software from ten years ago...

Still, with large capacity cards, a professional photographer could use a few lessons in file formats and conversions to get the most out of their images.  JPEG artifacts are nasty things and RAW is big, but converting to a PNG on a PC isn't hard.  I believe even MS Paint can make a PNG.

.PNG used to have licensing issues, but that hasn't been the case for quite some time now. Could be processing power, but honestly that kind of power is given away in cereal boxes nowadays (well it would be if they still gave stuff away in cereal boxes :()

Dunno. But the case still stands that for a variety of reasons JPEG is both good and bad.
