Why is it not available in Canon's DPP?
This is a new bussiness model for a Camera manufacturer to make money out of software.
The software they provide, sould be a complement for those who buy their hardware product.

Astrophotography is where computational photography shines and computational photography is Google's faivoraite technique.

The sweetness of that girl dominates any technical specifications of the 90D or any other camera.

HosseinG: This device is actually a hardware, like Camera and Lens.
Do the Camera or lens makers ask for money when they release a firmware upgrade?
And the upgrade is free for new customers that buy the very same make/model that the previous customers did.

@kb2zuz your examples does not sound like firmware update, they are more like some apps you buy for your laptop, your phone or your car.

tkbslc: Extending a product beyond the initial advertised specs would seem to create additional value beyond the original purchase price. Maybe charging for things like this is OK. You would be expected to pay for v2.0 of a software package for example.

Fixing bugs and issues with firmware should be free. That's just making good on the original advertised specs. That's like .1 upgrade for software.

I guess think of it this way. Would you rather pay $10 for an upgrade through firmware, or $100-200 for new hardware with this firmware included for free?

Canon released firmware for 7D and extend its capabilities for free.
This is a marketing/competition issue.
I think they do not see any competitor in that price range, so they ask money for adding features or extending capabilities.

HosseinG: For a 32MP camera with large RAW files I expected a USB 3.0 interface, USB 2.0 is so outdated.

@xmeda card readers are actually faster than USB 2.0 cable but not USB 3.0 or USB 3.1 cable. USB 3.x is standard for many years in smart phones with 1/3 price of this camera.

On article 2019 Guide: Apple iPad Pro for Photographers (259 comments in total)

A typical scenario for using this is to batch process some presets on 24~80 RAW pictures in LR or DXO and then upload them to the cloud.

The process on desktop, demands heavy load of computation from CPU or GPU and consumes a lot of power and spins up fans.

Does these iPads have enough GPU or CPU power and battery capacity to do this typical job?

XeroJay: This type of thing crosses the invisible line of what I consider the definition of photography. One day I won't even have to show up to shoot a wedding. I'll just have AI place the couple in a scene where they want, doing what they want, wearing the dress and items from an AI catalog...

@XeroJay
I guess soon they do that on their smartphone by themselves, they won't even bother asking a photographer (if it is still photography).

Yes it is possible, but the probability is equal to the probability of somebody hit by a truck in his living room.
Seriously, considering all the requirements for a successfull hack on a DSLR and the amount of money the hacker might ask, this is not a reasonable target for any hacker.

In reply to:

bceye: They simply added a silly button in DXO that creates a TIFF from a selected image, and then loads that TIFF into Nik app of your choosing. This is not an integration, nor new Nik capability to read-in RAW files. They should integrate Nik fully into PhotoLab, and it should become another preset you can play around with.

You mean, the modifications do not go to .dop file?

TORN: I have some more great ideas to increase security:

- What about a blood sample?
- Wearing a tracking collar when travelling.
- Limiting my visit to certain foreigner areas.
- Having a local guide or a drone follow along during my stay.
- Keep my first born locked up while I do vacation to make sure I behave.

Maybe it would be best to let nobody visit the country at all? Simple solution for all problems and cheap to execute.

@TORN whatch what you post here, in a few month they will check your DPReview activity too.

HosseinG: It blocks pop up flash light.
You need to remove it in case you need flash.

If you position it on a side of lens, how do you hold the lens with your hand?
How do you access to zoom or focus ring?

jyw5: 3 years ago, I did an experiment with my Sony a7rii. I took five landscape photos handheld 35mm at f8 during the day on the RAW setting. I exported them to tiff files with DxO optics pro. Then I used another software to upsample the resolution from 42mp to 84mp. Then I aligned and stacked the photos into one 84mp photo. At 100%, the 84mp photo actually showed more detail than any of the 42mp photos. I also downsampled it back to 42mp and it showed more detail than the single photos at 100%.

It works and this idea has been used in a similar but much more complex way for a long time in astrophotography.

Fortunately, for me, there isn't a need for 84mp photos...although, I wonder how a crop of a 84mp photo would compare to one single 42mp photo of the same subject at a closer distance. or better yet, if I did this test with my Sony APSC A5100 (a 24mp camera), how would the processed, upsampled and stacked photo compare with one shot with my a7rii (using the same lens FF lens)?

This works as you mentioned on landscapes and still scenes.
Most of the time you want to take a picture of some action, sports,etc., I do not belive this technic gives us a good result.

1) Isn't it more practical and less expensive to use higher resolution front camera?
2) Doesn't a red LED on cameras do the countdown for people effectively rather then a fold display?
