So for the most part, Canon, Sony and Nikon “colors” are present in the JPEG files produced by the cameras but only to a minor extent present in the RAW files.

RAW files don't have color. Color is created in the conversion process, and different RAW converters will create different colors.

thats not true 🤪 the voltages are measured from the coloured filter/diode. and i beleive every sensor maker has there own colour mixtures.

shooting portraits professionally. there is a big difference even using the same brand, to date my a7iv is by an easy margin the best at producing near perfect skin tones, my pentax k7 back in its day was by far the best of any brand, the olympus em5mk2 was good as well. but ACR raw converter is all over the place and not even close to the cameras own raw converter. so i pick one of the defaults that best suits my needs.

Starburst from X100VI Fujifilm March 16, 2024, 9:18 p.m.

@AlanSh has written:

I wanted to see whether the theory of stopping down a camera and aiming at the sun would produce a starburst. Now, I don't know if this is good or bad, but this is what I got. I've upped the exposure a bit and added some sharpening from the raw file. It's resized just so I don't take up too much space.

The camera had a UV filter on and no lens hood.

Comments invited (good or bad as I have no preconceived ideas).

Alan

sun /star burst must be a contributing factor to an image, in this case i wouldnt of even noticed it if it wasnt the theme of the post.

not putting down the v1.

Okay then. Again, I've been talking about the V3 ... but I also have a V1 as a backup. It's not nearly as versatile as the V3.

Quoted message:

just an interesting read from 10 yold cameras that were state of the art. were so fast at somethings ans so slow at others. so the bottle neck will always make a camera more difficult to use in the real world. its like the a93 can shoot 120 frames for 1.6 secs takes 11 secs to clear and can only shoot 105 jpegs before the buffer fills.

The Nikon 1 series is full of contradictions. Each of the 11 models supports 1/60s flash sync with electronic shutter. The AF system in the better models is extremely good for its time. But there are also plenty of irritating shortcomings when compared to other systems. I like my Nikon 1 cameras, but they can't take the place of my other cameras that have very different strengths and weaknesses.

a friend has a v1 and he loved it for shooting birds side by side with his d500.

Don, your a6300's readout is four times slower than syber's 1v3.
immune to feedback?

not by the look of the test images.

I told you why yours look similar: you were panning slower. Your slower sensor shows the same level of distortion when panned at slower speeds than mine.

Quoted message:

after reading reviews on the 1v3 every states that nikon over stated the specs and back then every did.

Bullshit. I also pointed out that the V3 can sync electronic shutter with normal flash (not HSS) at 1/60s. So we know it's at least 1/60s, and testing has shown it to be 1/80s. Why do you resist accepting that?

they said my em12 could sync at 1/60 sec as well but i couldn't get any more the 1/15 😉

Whoever 'they' are and whatever 'they' said, the V3 x-sync at 1/60s is a fact. It's in the manual, and it's in the camera, and I can shoot with flash at 1/60s with no issues.

Quoted message:

isnt it funny looking back, i just read the specs 50 secs to clear 40 images 😆 they called it the speed demon 🤔 shoots video for 10 mins max 3 min at 120 frames at 240x 320 or something like that. why i love my 74 there is no buffer clearing time even if i shoot a 400 image stack. no blackout evf. my a6300 is ok but still a dog by comparison.

As usual, I'm not even sure what you're trying to say. Are you finding things to disparage about the V3 because you don't like the fact that its readout speed is far faster than your camera? This thread isn't a pissing contest. It's an exercise in correcting your misconceptions.

Drinking too much of the Sony kool-aid?

m.dpreview.com/reviews/sony-a7-iv-review has written:

Our first look at the rolling shutter rates suggests this isn't an especially fast sensor. 14-bit readout of the whole sensor for stills takes around 1/15 sec (~66ms), which is around seventeen times longer than the super-fast a1 takes to read out its sensor. This means silent shutter mode is likely to result in significant distortion with moving subjects.

A7.4 is about eight times slower than om1.

the a74 flogs the om1 😁😁

not by the look of the test images. i cant pan any faster ,i even pre focus swing the camera till the subject hits the center and take the shot. that would be like panning a race car. after reading reviews on the 1v3 every states that nikon over stated the specs and back then everyone did.

something is not right. is your camera reading the sensor the other way ?

Not right? I don't know which way the sensor reads. Of course it reads across the short side, if that's what you're asking. As I said, one shot was panning toward the right and the other shot was panning toward the left.

fast pan and stationary shot.

Yes, that example shows a bit of compression/expansion.

Here's an example that shows more. The V3 electronic shutter has a readout speed of about 1/80s. I guess 1/8000s was unnecessarily fast, but I was panning pretty fast and wanted to avoid blur. I stopped after catching these two almost perfectly framed shots.

The shadows on the bird are not consistent with the shadows in the photo. In the bird the light comes from the right side and in the photo it comes from the left.
Flip the bird horizontally

not up to me to make it perfect .not my image ,just an idea.

@DonaldB has written:

... i looked up the specs of your camera and its 1/13 sec sensor speed.

Where did you find that specification? These tests show readout speeds of about 1/80s for the Nikon V3, as I said:

nikon1user.blogspot.com/2014/10/electronic-shutter-readout-speed.html

I also did my own testing in the past and came up with the same estimate.

I think you mean its about 13 milliseconds, or 0.013 second, which is about 1/80s.

Oh - and I can give you another reason why the 'specification' you're stating is completely wrong. The V3 can fully sync using normal (not HSS) flash with electronic shutter at speeds up to 1/60s. That would be impossible if the readout speed was any slower than 1/60s.

sorry that was Jacs that has the canon R

my a6300 has a nearly 2x faster sensor read out speed. which is probably the difference is a lot less. to be honest i couldnt tell which one of your images was the correct image or not. so why have we even captured an image at 1/8000 sec when the sensor is 1/80 ?

Not true.
The a6300 electronic shutter sensor readout time is much slower, 1/20 sec.

Maybe you used EFCS instead of ES?

his eos r is 1/13 sec not 1/80

The R is 80ms. 1 / 0.080 = 1.25 or 1/12.
