FAQ: Canon EOS 450D / Digital Rebel XSi Volume III


26.03.2009 11:31:00
Canon has introduced a new digital SLR camera "top entry-level" with video recording in the resolution of Full HD. Novelty called Canon EOS 500D.
By design, one in a 450.

quote:
In Raw and 450D can even shoot at ISO 6400. . .
you show me an example of a frame at least for 3200. . It will be interesting to evaluate detail, smoothness, color transitions and overall image quality.

26.03.2009 11:51:00
and where did you get that iso3200 software?
given ekspokorektsiyu 2, we can assume that the iso3200 - iron, and then goes as described KM-300, t. E. A stretch of exposure.


you show me an example of a frame at least 3,200
show what is possible, but it is not smotribelno.

even if the day sfotat 1600, the 6400 can be pulled quite acceptable. (No worse than the same 1600 in a dark room).

I also speak about that. I have 1,600 in all conditions, even without pulling it turns a trash because of banding that the frame immediately flies away in the trash. At the same time on the 5D (old) in 1600 with the correct exposure can not even handle shumodava. Little or remove luminance noise - and be clean shot. . .

26.03.2009 13:20:00

5d, of course, but it is good
450d more than 2 foot (1-1, 5)
so its about 1600, as 800 at 450d (should really take into account that in 1600 it - it's really 2000, and therefore 1, 5 foot difference)

and its 3200 less than 800 at kropnutyh cameras (but really this is not 3200, and more)


even if the day sfotat 1600, the 6400 can be pulled quite acceptable
but has only theoretical interest


26.03.2009 15:50:00

But right after all noticed how Makar Canan achieve ISO3200 with exposure compensation in two if the ISO3200 is as you say but already two of ISO800 (1600?)? And why tezhe 12800 at lower Mn?

26.03.2009 16:23:00

and what prevents them from doing the exposure compensation to three feet?
yes, this is not on the menu, but the chamber has
though, I will not argue, may 3200 and hardware

And why tezhe 12800 at lower Mn?
is like?


26.03.2009 18:45:00

not argue, may 3200 and hardware
see, the matrix is ​​the limit of its capacity for sensitivity. And no matter what method is achieved by 3200. It is possible to raise the voltage on the matrix, thereby increasing its sensitivity, you can underexpose the frame and pull the processor. The noise level will be approximately the same.

26.03.2009 19:32:00

yes no
try to capture the image on the iso-200 s -1 exposure and then pull in the iso-400
and immediately put iso-400 - extended version will be worse

27.03.2009 8:24:00

But I also play around like that. Something does not add up.

possible to raise the voltage on the matrix, thereby increasing its sensitivity, you can e not. This is not the way you spoke of in the beginning. With this clear to me.


And why tezhe 12800 at lower Mn?
is like?

Well, just as is the case with digital zoom. More details will not say I do not know. Perhaps a pair of triple piksiley next start working as one but increased sensitivity.


27.03.2009 8:43:00

ie sensitivity 12800 15 megapixel resolution is not? (No detail, and resolution of the file)

general, you can also make pure Bayer resolution without interpolation, the pixel will consist of RGGB (well, or how it is there, depends on the camera) component, ie, the resolution is 4 times lower, but the pixels will be released 4 more times. are there any converters equal in nature? it's purely a software thing


but interestingly remove 1600 with one exposure, and then move up to 800 and remove immediately at 800 - which is better?


27.03.2009 10:53:00

is sober but I do not selenium in it.

27.03.2009 10:55:00
And why no one believes that the new gapless matrix and a new processor simply allowed to take one more step to ISO? Personally
in noise frame see clear progress over the past five years.

27.03.2009 11:04:00
but interestingly remove 1600 with one exposure, and then move up to 800 and remove immediately at 800 - which is better?
Rather shoot at ISO800 1 and compared with just ISO1600.

27.03.2009 11:08:00

50d because such benefits are not shown in my opinion


can I properly formulated, but sutv is to compare the shift down the exposure and frame with a smaller iso


27.03.2009 11:19:00

I just believe. Although the word sounds strange believe.


tried in different ways and the difference between 1600 and 800 for noise noticeable. The most interesting was the version ISO1600 -1 against ISO800. Gain exposure to get enough to cope IS and exposure was less. But noise. . . . But there is one significant BUT, about which I have said many times. This is if you shoot in the RAV at such ISO, yes noise gives to feel the difference between ISO800 and 1600 in favor of the former. But if you shoot in JPEG with on noise reduction, the result is already in favor of ISO1600 and significant as noise and camera shake on.


27.03.2009 16:21:00

such as 1600 - 1 stop in the converter must be less noisy than 800

theoretically and with noise canceling is not clear, I did not compare, but really Chamber zhpeg zhaet the same detail as the converter, which is more noisy?

27.03.2009 17:24:00

compare himself.


such as 1600 - 1 stop in the converter must be less noisy than 800
This is assuming that 1600 is softvarno of 800. However, this does not seem so.


27.03.2009 20:57:00
you would still pulling the lenses do

Because it's there nafig not needed.
This is not reached until the shutter speed of the order of 1/30 of a second.

Not so this besmyslenno as you think.

imagine and represent the percentage of such situations relative to the total number of shots and do not want to pay too much.

28.03.2009 9:56:00

Yes, yes, I understand your position. Very reasonable accuracy and clarity.

28.03.2009 13:44:00

yes, 1600 -

hardware but it does not mean that in 3200 500d also hardware


28.03.2009 19:32:00
Good day. Ripe for the purchase of a subject. Is considering several options, stopped on ebay. ca for friend can bring, t. To. we (Samara) carcass 400D only costs ~ 29 000 In this regard, came upon [ http: // cgi. ebay. ca / CANON-EOS-Rebel-XSi-450D-Digital- ...: 12 | 39: 1 | 240 1307 ] here is such a [/ url] will cost ~ 34,000 to buy, as the first CZK. There is a sense?

28.03.2009 19:47:00

It would be better if your friend will go and buy the camera in the store without it outright junk, including lenses.
 

28.03.2009 21:03:00
Lenses
not much, but when you consider how much it costs in the end he is able to make sense. But it (tyts!) most what you need. And all 1000ue!

28.03.2009 21:24:00

option from much nicer

but in general it is best that without mountains of trash. . .

28.03.2009 22:38:00

version of xkimx much nicer
+1

because in the first embodiment, a mountain of trash _deystvitelno_

28.03.2009 22:40:00

thing you said, an option that must be
true and junk nasuyut, but it seems that for nothing

28.03.2009 22:48:00
especially pleased with its usefulness tripod Flexible Table Top Tripod

28.03.2009 23:03:00

so what, 450d keep it saw in the internet photo of this tripod SLR

28.03.2009 23:23:00
complete with 70-300

28.03.2009 23:25:00

of course, no

28.03.2009 23:30:00
true and junk nasuyut, but it seems that for nothing
yes there from barohla unless tripod and flash. though even then it will fit for a compact Nikon type R6000.

29.03.2009 9:10:00

barohla unless tripod and flash
not disagree
stuff almost all - these old film whales instead of native? ?
nafig, were they at me, still the same stuff
body \\ shu converters - too nafig-nafig such
filters also suspect that fucking

only normal that there are going - this card and remote

29.03.2009 11:12:00
Good day) Thank you for your timely feedback. Yes, indeed, I share vyshenapisannoe, but better options have not yet found (maybe bad looking?) Junk in the greater extent remain as a present Canadians - for drag this pleasant appendage between continents - not of precious metals) Shop - of course, is also an option, but there are more, but we must look. Here pleasing 2 lenses (as they say, feel the difference) In general, IMHO, a good starter set, am I right? )

thanks for the link)

PS go to google something without chUmodanov and tripods)

29.03.2009 11:13:00

I'm talking about your own version.

29.03.2009 12:13:00

here just gave a link to a nice set of

I'm talking about your own version.
realized thinking about the first

Acquired vspyshechku toy (Rekam what that) for the 250r. Oddly - flashes. Can work as a slave in the momentum built from. I plan to use as a side or backlight illumination.
Having difficulty:
which mode to set the built-in flash (synchronization on the first or second curtain, evaluative metering or suspended, ekspokorretsiya needed or not?) - When to take a picture without rivers - beyond the normal frame, c rivers - the dark for some reason.
When shooting on a bar of soap Samsung S85 - all right. Apparently
450D somehow corrects the frame depending on the scene illumination. . . How do I disable it?

30.03.2009 8:56:00

c rivers - the dark for some reason.
because the built-in flash gives two pulses in any mode, rivers triggered by the first
can overcome this by pressing * before shooting, and then take the picture

30.03.2009 11:59:00

This step is buying a cheap outbreaks were many Alas, the only digestible version - is to buy a normal ETTL flash. Canon is better, but go and Sigma. . . Everything else works very poorly and unpredictably. . .

30.03.2009 12:07:00

Everything else works very poorly and unpredictably. . .
me radiosinhronizatsiya all such suits, so do not have to buy 2 flashes

Radiosinhronizachiya what? The question of exactly two outbreaks.

30.03.2009 12:53:00
Radiosinhronizachiya what? The question of exactly two outbreaks.
I understand that the remote start was interested in flash

30.03.2009 12:59:00

because the built-in flash gives two pulses in any mode, rivers triggered by the first
in purchasing a flash sync mode, there are two - one double pyhu and the other for once.
when you turn on the first - the flash will not blaze apparently double pulse too fast for her.
In the second mode - works, but the frame is dark, as I mentioned above.

I understand that bine interested remote start flash
interested in sync

30.03.2009 13:02:00

but the frame is dark, as I mentioned above.

likely duration and pulse interval is not the same, this is often the case, it is necessary to check when buying
try to shoot *

should be finished adapter

30.03.2009 14:27:00

should be finished adapter

Which adapter? She is the light flashes.

30.03.2009 14:36:00

Which adapter? She is the light flashes.
pah, adapter and wanted to say svetosinhronizator
not about thinking while writing
 

31.03.2009 16:04:00

bought similar naborchik (18-55 & amp; 55-250 IS) on eba from the same seller somewhere half a year ago, as a starter set is even nothing - all have what it takes for the first time, although all but fotika and family of lenses, frank junk. Lenses normal back-and-tricks fronts were found.
