Which purple hue from Nikon or Sony is more accurate if you can recall? I see a significant difference in blue-purple hue between cameras.
Chris Yates: Kinda pricey for a Chinese brand.
That's actually cheap as fast lens like that often fetch around a thousand dollars.
It seems like photoshopping is faster and easier on iPad Pro than on a computer with Apple Pencil. It just works. And the image - wow, you can zoom in and out smoothly and fluidly... and cloning out objects remove them instantly.
And I really like the note taking app!
You can open and edit RAW files on iPad Pro according to Apple's website:
"The A9X chip is capable of processing data so quickly, it demanded a new memory architecture. iPad Pro features a revamped storage controller that helps deliver performance better than some desktop computers. This increases read and write speeds, so you can quickly open even the largest files. Like the big 4K movie you just edited or all the RAW images you imported from your HD camera."
RichRMA: Roughly 2x the resolution of the current 50mp FF sensor.
2x? It's 5x... 50x5=250MP.
Makes me wonder if the lens can resolve all the details with so many pixels? I recall that the lens does have a limit to how much it can resolve details.
Sony, when are you going to give A7RII users a lossless comopression option?
www_zeeshan_de: TheDSC09021.arwis the ISO 100 Image. I just ran it through originalraw. All i can say about the original JPG result is, that the image is massively underexposed. Maybe its underexposed by 7 stops. Boosting that image by 6 to 7 Stops and complaining afterwards doesnt make any sense.
Who on earth takes pictures at EV-7 GENERALLY ??I never do.As a photographer its your job to expose the Sensor of you digicam CORRECTLY to get the maximum SNR.
I think Sony did very well here, providing 40 megabytes for each ARW file (lossy)instead of70 megabytes for each ARW file (lossless).
Lossless RAW with 70 megabytes may be only useful for a few boosting brightness by EV+7.
But the majority of the photographers can save a lot of Space, and most of them, never take pictures at EV-7.
Lossless ARW with 70 megabytes filesize may be a welcoming option, but it should be optional, but i would never use it.
@www_zeeshan_de, of course, you don't need to shoot at EV-7 (I don't think there is any camera with that much range in EV). The point of the article is showing how it makes little difference between shooting with a given high ISO in camera and pushing the ISO in RAW editor from an image taken at ISO 100 if you're using an ISO invariant sensor. When you shoot at low ISO despite being underexposed by a few stops and develop in an editor, you could preserve highlights better.
With that in mind, using the ISO invariant sensor, it's a good idea to expose for the highlights and push the shadows in RAW editor and not worry about the chroma noise that would have popped up if for an ISO variant sensor.
The technology behind the ISO invariant sensor is exactly why I switched from Canon to Nikon. I do see huge differences in shadows when pushed between Canon and Nikon. And DPReview confirms that in several tests.
alligator: How to do a +6EV push in ACR?
@falconeyes I had no idea that the slider will magically have 10EV+/- when converted to 32-bit! But I did notice a strange change. When I "Edit in photoshop cc" and I convert it to 32bit mode then then save it which naturally adds 32-bit TIFF in LR and for some reason, the image looks more like the default JPG (more contrast/saturation) and is overall brighter than the default on NEF. In fact, the TIFF does not match the TIFF in PS CC at all. But I was able to use the EV slider and get far more details in shadows than I could in default NEF. Definitely something is going on. I am just stunned how much potential there is. I am using Nikon D5500
@Rishi it would be nice if you could report your findings with falconeye's methods.
joao 43: The subtitle says ISO100 not ISO100 pushed +1/3/6.Misleading. Even when you read the whole article.
The dropdown menu on this page doesn't state that the 100 ISO was pushed 6EV. In other reviews, it would show that. Here's an example of a webpage showing dropdown menu of different EVs taken at a given ISO:
The lack of consistency is what threw me off at first because Iv'e read reviews and expected the dropdown menu to show +# stops along with ISO.
Cheng Bao: An interesting discovery:http://www.dpreview.com/reviews/image-comparison/fullscreen?attr184_0=100&attr184_1=200&attr184_2=400&attr184_3=800&attr184_4=1600&attr184_5=6400&normalization=full&widget=266&x=-0.9395524644693076&y=-0.13554790498019378
Around the overblown sign, at ISO100, there are posterization artifacts that could be easy seen. I think, this is the one of the best demonstration of sony's lossy raw scheme.
However, the posterization is gone as ISO goes up, why?
The posterization you see is the result of lossy compression, discarding significant amount of color when adjusting in RAW editor. Lossy compression is focused on discarding color in areas that it thinks you won't perceive taken at that EV rather than how you may perceive at a different EV in an imaging editor.
Obviously, in order for a camera to be truly ISO invariant requires that the RAW file NOT be lossy-compressed otherwise it loses its progressive ISO invariance advantage.
I agree - it should have said, "100 +6EV Pushed" - it's odd because in other reviews, it was stated that way.
It's about time! I always wondered why they don't just reset the photosites once they are full and repeat the process until the shutter is closed. Of course, that would mean that RAW editors have to understand the "reset" algorithms and on those highlight data that are added after the reset be "compressed' like film.
ARTASHES: As I can see what he is doing is reposting the screenshots and not downloaded ones, so making screenshot of a screenshot again and again will cause this degradation with or without instagram.
Richard Butler, there are options to reduce color to 256 just like GIF (PNG-8) and that will reduce the color and that means a lot of color data will be discarded but it is still lossless during compression/decompression. You can blur the image a bit and it will reduce the size even more so. However, you can encode and decode it again and again and the image will never degrade. PNG works like GIF and we don't call GIF a lossy compression even though GIF can only support up to 256 colors. Naturally, iPhone PNG uses the standard true color PNG (not PNG-8).
MrCool69, screenshot on iPhone does not degrade at all since it uses PNG which is lossless. What you see is the result of Instagram app encoding the screenshot into JPG format.
Just get a waterproof case for your smartphone and you're good to go.
And I remember how people said that there's no way a digital camera can outperform film in just a decade. If it was shot with a digital SLR camera, it would be sharp, clear, and more saturated. Low light? No problem, just boost the EV in RAW processor (especially the Nikon/Sony types).
I am sure glad film is over.
What is interesting is when I did pixel peeping at 400% on a pixel shifted image, I am noticing "color mosiac pattern" on solid black lines where the resolution lines are showing. I don't observe that with Foveon images. It looks like it's just a natural artifact of pixel shifting.
It could be just JPG artifact but I suspect it isn't. It does look like something that could arise from pixel shifting but it's still better than "normal."
EdBen: You can see it is not quite as good as Olympus pixel shift (on OM-D E-M5 mk-ii) though, but on the other hand the Olympus is much more limited in ISO.
Are you kidding me? The OM-D m5-II looks really awful. Definitely not worth "shifting." The K-3II seems to record all three colors at the same pixel site rather than to enlarge hence having razor sharp details and lacking color moire.
