Practicing with closeup rig. Canon 30D, 100-400 zoom, 1.4 extender, closeup screw-in filter. This photo is full frame from a medium size jpg photo. The only post-processing was a little bit of sharpening and a tweek of levels in PS.
If I was you I would shot in RAW you can do so much more in post processing and your pictures will look a lot better. Not that any thing is wrong with your photos! But you will see the difference. every time a JPEG is opened up it degrade the picture.
Me either.. Be careful about KR equipment reviews, many of his reviews are of equipment he has never used or seen, he just read the specs and assumed.
I also cautions about his absolute style, ie his view that RAW is not needed shoot JPEG only. I do think KR has hurt more amateurs by appearing to be a know it all and leading the new DSLR user down a path more suited for his style. I find Thom Hogan much more reliable and he is also very honest, he nails Nikon when they need it and praises them when they deserve it
But most good Photographer I talked to think he full of it. This guy also tell you you don't need a high end camera but he shooting with a Nikon D3 6 thousand dollar camera... But it up to you guys if you beleave everything this guy say, I know I don't!!
For everyday shooters who do not do post-processing JPEG is the route to take. Most (99.9%) of high end shooters shot in RAW though IMO. Go to any photography forum, talk to anyone getting paid to take photos and they are shooting RAW. With JPEG, the more you edit and save, the more you lose in picture quality. It just keeps degrading. With RAW, you lose nothing.
Rockwell's opinion is from 2008. A lot has changed regarding RAW files and the software that handles it. I have never had a problem with software or download speeds off the card.
