varbuut kaads zina vai iespeejams kautko mainiit/remonteet pa garantiju ja man zem1sec paraadaas 2 trekni beigti pikselji? izrakaajos bet canon laikam iipashi neafishee shaadas lietas.
viens čalis tieši gaida, kad kāds laiciņš paies, jo viņam ir pāris beigtu. kamēr kas cits nenotiks vēl, tikmēr jau bildēs, bet kad kas notiks, tā lai maina arī visu matricu
nu jaa bet nebuus jautri ja atsviediis atpakalj un pateiks vari ieskrieties, ir lietas kuras njem un kuras nenjem galvaa gribeetos uzzinaat noteikti, man jau taa kaa buutu laiks objektiivs jau vienreiz spruudis tagad veel tie pikselji...
Tev kā patērētajam ir tiesības zināt pilnu garantijas noteikumu izklāstu. Pieprasi un dabūsi. (Kaut gan Latvijā laikam arī pa galvu par šito var dabūt...)
Hot un dead nebūs viens un tas pats: Hot pixels are individual sensors on the CCD with higher than normal rates of charge leakage. They can appear as small pixel sized bright points of light on longer exposures. Every pixel on the CCD has some charge leakage, and if you expose long enough, any pixel would light up. On a long exposure, you will see pixels ranging from just barely visible to possibly bright hot starlike points. There might be a few bright hot pixels, more intermediate one, and lots of very faint ones, an entire spectrum of brightness. At the low end, the faint hot pixels contribute to the noise in a picture. All cameras on the market today have "hot pixels". Because the rate of charge leakage is the same for a given pixel over time, the longer the exposure, the brighter it becomes. This charge leakage is worse at higher temperatures, even a 10 degree difference can be seen on an exposure. Hot pixels are often just one site, and are one of the colors of the color filter array over that site. In the case of the CP990, hot pixels are usually Cyan Magenta Yellow or Green, although other colors are possible if you have two adjacent hot pixels. Green is the most popular color for hot pixels because there are more Green sensors on the CDD. Most cameras made after 2002 now have a noise reduction technique used on longer exposures that involves taking a duplicate exposure with the lens covered that is then subtracted from the main exposure. Also note that some cameras use software noise reduction that makes hot pixles appear White instead of their normal color (Minolta and Sony do this).[/code:1]

nuu tad sanaak ka tas ir normaali.... citaadi es te dabuuju pulti, pameeginaaju bulb un shitads dazhs paraadijaas... :) un ja pa guugli jau ar neparakaajos! :D tur droshi vien butu uzzinajis to pashu.. bet paldies sasar ka izpaliidzi slinkjim! :p
he.. mani arii paraava zinjkaaree cik tad man to beigto pixelju - paarbaudiiju..... NEVIENS.. :roll:
neva buut Uzliec max iso, un expoziiciju uz max laiku (kādas 30s) vācinju uz stikla virsū, uztaisi bildi un pārbaudi tad...
nu , bljaaviens, tikai speciaali prieksh tevis panjeemu veelreiz un paproveeju uz 30 sec (liidz shim bija 0.5, 2, 5 sec proveetas) .. NAV MAN BEIGTU PIXELJU pie defaultiem Threshold liimeniem 60 un 250. Hot saak paraadiities tikai pie Thr. 3 paraada 5 pixeljus,kuriem saakuma veertiiba luminancei ir 3 Dead nav vispaar .. tiem kas paarbauda ATCERATIES - RAW konverteejot uz TIFFu - Blakcs ir jaaieziimee kaa 0 nevis defaulta 5 vai kaa nu kuram tur salikts.. citaadi neparaadiis shos pavisam siikos defektinjus, kuri nemaz nav defekti ....
