Advantages of RAW
Now that we’ve dealt with Ken’s objections to using RAW, let’s look at some of its advantages. These are threefold: in quality, latitude, and future uses.
Quality
JPEG is a "one size fits all" solution. In-camera sharpening is applied to produce a pleasing 8 x 10 print, but it may be too much for an 11 x 16 (or bigger). The demosaicing algorithms aren’t as good as they could be: they may produce moiré, stairstepping, "checkerboard" artifacts, or blockiness in the red channel -- to name a few issues endemic with Canon pictures. (Nikons have issues of their own, too; all cameras do.) Most of these issues are too minor to make a visible difference on 8 x 10 prints. At larger print sizes, even "amateur" ones like 11 x 16, they do start showing up. While they probably won’t be distracting to the casual viewer even at that size, they’re nevertheless annoying. With RAW, many of the problems can be avoided. More to the point, the conversion settings can be tailored for the particular print size under consideration. As demonstrated above, RAW does make a significant quality difference even in "perfect" in-camera pictures, even if it only starts to show up past 8 x 10 -- and much more so in scenes that were, for example, either too contrasty or not contrasty enough to produce a "finished" JPEG out-of-camera, no matter how you exposed it.
Latitude
With JPEG, once you shoot the picture, you’re more or less locked into the choices you made when shooting it. If you decide afterwards that maybe it’d look nicer with a warmer color balance, a pulled-down curve for a chiaroscuro look, a pulled-up curve to show some more shadow detail, more noise reduction for a "cleaner" look, or less noise reduction for a more "textured" look... well, you can do much of this in 8-bit post-processing, but your latitude is pretty severely constrained. Do too much, and your skies, other gradients, and shadows will develop visible posterization, your noise-reduction will erase texture detail, or you’ll end up with blobby shadow detail. With some nifty tricks, you can push it a little further... but beyond that, well, basically, you’re out of luck.
Lake Qaraaoun with Mount Hermon in background. West Bekaa, Lebanon, 2003. Canon EOS-10D with EF 35/2, converted with CaptureOne DSLR LE.
Sure, there’s nothing wrong with adopting the "slide shooter" attitude for digital photography, but with the marvelous post-processing options the digital darkroom gives us, this is tying a large, unnecessary ball and chain on your leg. RAW gives latitude to adjust everything -- color balance, white balance, tone curve, sharpening, noise reduction, contrast. You even get maybe another half-stop of exposure latitude in the highlights, and at least a stop, maybe two in the shadows. Negative film it isn’t, but you breathe a lot more easily than with slide -- and not only if you’ve made a boo-boo behind the camera. The fact is that RAW significantly expands your creative options.
Future uses
We’ve already seen what advantages technological development can provide for working with RAW files. Alternative demosaicing algorithms provide different looks and feels, sometimes with dramatically increased quality. There’s no reason to suspect that this development will end now. Not only that, but you might find uses for your pictures that you didn’t intend when you shot them -- and the latitude RAW gives you for adjusting them may make the difference between a superb result and a so-so one. RAW converters will continue to get better, and there might come a day that you’ll wish that your JPEGs were RAWs instead. That happened to me just a couple of days ago. Yep, RAW might be a bad idea for storage 50 or 100 years into the future, but it can give you a lot in the next 5 or 10 years. But do archive a converted copy of your work too.

Par Ls 500 var atrast lietotu Canon 28-70 2.8 L (nesen ss.lv bij viens pa Ls 550).
Principa Tavam prasibam atbilst ari Canon Canon EF 28-135mm f/3.5-5.6 IS USM. Atsauksmes puslidz ok, cena ari -> ~Ls 300.
Uz 1.6 crop faktora kameram, gan piemerotaks bus Canon EF-S 17-85mm f/4-5.6 IS USM, atteicigi pa kadu simtu dargaks.

kursh tieshi Tokinas objektiivs tas ir? nav jau obligaati jabut fotografam ar liikam rokaam lai dabuutu bildes miglainas - ja nepietiek gaismas un objektiivs ir "leens", tad sporta fotografeshanaa biezji varetu sanaakt miglainas bildes. tapee ari prasu, kursh tieshi Tokinas stikls tas ir?

Lieto pec iespejas platak atvertu diafgragmu un pec iespejas garaku fokusa attalumu.
Bildeeju gan es ar ziepju trauku (ciparu), varu reguleet iso50-400, f=2.7-8.6 un shutter speed 1/1000-10 sec. Stativs arii ir .
Ar ziepju trauku, del mazas matricas, ir gruti speleties ar asuma dziljumu - puslidz viss sanak ass. Visizpludusakais fons sanaks, ja fotoaparatu piebazisi maksimalu tuvu bildejamam objektam, tacu tad sejas proporcijas un perspektiva bus nelaba. | | Offline | | |

| Izplūdušākais fons būs pie garākā fokusa attāluma (lielākā zoom) un pēc iespējas lielāka diafragmas atvēruma (mazākais iespējamais f)
Tad vēl ieteiktu modeli pielikt maksimāli tuvu un fonu novietot maksimāli tālu no modeļa, jo digi ziepjutraukiem ir liels asuma dziļums

Skaidrs paldies!
Taatad es laikam visu daru pusliidz pareizi, tikai kaa tu raxti - nekas man nesiid . Ja lieku max zoomu, tad atkal kadreejums nekaads .
