Is there any loss of quality when moving pictures from a WIFI capable camera(such as a Nikon D5300) to an IPad Pro using the WIFI, as opposed to using the SD to lightning connection? Is it the same with both JPEG and RAW?

Do not think that is going to work. You will need a cable to connect the card to your iPad Pro. I’m assuming it is the new one correct? Otherwise I use WiFi to send pictures to forums and no quality issues.

It is my understanding that file transfer via WiFi/Bluetooth is a byte by byte process. If the file header checksum disagrees with the device calculated checksum, the file transfer fails and you will get a checksum error. If the image file format can not be interpreted by thr device, file transfer fails and you get a file unrecognized error. With jpeg this never happens as joeg is a defined standard. There is no defined standard for RAW so there is no expectation that a Nikon raw would be the same as a Canon raw or any other camera raw. Consider my experience with Sony raw (.arw file extension). With the a6000 its .arw could be converted to .dng but the a6300 .arw could not be converted to .dng. One of my problems is that my Photoshop versions are too old for any modernish camera and incompatible to modern .dng converter version. This entire compatibility/incompatibility/PS/.dng issue is entirely due to their being no industry standard for raw files. If your camera manufacturer offers software and that software allows an image format compatible with Photodhop then you are home free, otherwise you are restricted to your camera's software for editing. In camera buying, how many look into the image raw file compatibility issue in its complexibility.

If you send over WiFi, you are sending bits of information to the iPad; very similar to using the internet to send bits of information to your iPad. It doesn't matter if it is a JPG or RAW. All the WiFi cares about is you're sending a file. All the iPad cares about is it is receiving a file. There will be no loss in quality if you send it by WiFi or by USB cable. (My personal preference is to use a cable as I batch d/l and USB is 10X + faster.)

NOW, the tough part. JPGs are universal and recognized by all computer devices with a display. A RAW file is proprietary and needs to be read and translated in order to be displayed. If you are using some form of Nikon software, you will probably be able to open that RAW file to view. Without Nikon software you would need some 3rd party software to open the RAW file in order to view it.

The good stuff is sending JPG (or JPEG, JPG 2000, etc) is a smaller file than a RAW file and still the accepted way of sending photos.

I’m not sure if you are using WiFi to send your photos to your new iPad Pro, but connecting the card to the iPad, is so easy and you don’t need WiFi and it downloads your raw files extremely fast, in my case, even 64mp files.

Fuji has an app that allows me to transfer images via WiFi successfully. The transferred images are not degraded by being transferred in this fashion. I previously tried with no success to use WiFi to transfer images from Nikon and Olympus cameras.

Joe Blow's "Now the tough part" remark is why I have advocated that some professional group that has standing should define a raw file format that would become a standard. JPEG are the initials of a professional group that has standing for doing this. What if a huge number of the UHH membership (now 70,000+) were to launch a campaign to get that done. It is doable as it is just binary file coding. What say we all get on high horses.

i don’t know why you are using WiFi when it is really simple to to take card out of camera and insert it in an adapter attached to the iPad Pro and transfer jpeg and raw files. I do this every time I travel. Never had any trouble with this process. But the best method is what works for you. Good luck. .......George

Me, for one. I know I am at my last camera (in brand line) upgrade and still be able to use Ps CS6 / ACR 9.1.1 with my Pentax K-3, A K-3ii, K-1 or newer, it would be time for Ps CC.

DNG; Adobe's, used by Pentax and Leica.

The last time I visited Adobe's web site for DNG I found a list of versions and which Photoshop versions were compatible. I choose the newest version compatible with PS CS4. That one could convert a Sony a6000 raw file but it could not convert a Sony a6300 raw file. Therefore, the two raw files are different. With a standardized raw firmat this would not be an issue.

All my Pentax cameras work with DNG and CS6. But likely only the K-100D (6.1MP) would work with Pentax PEF RAW and CS4. It is rather old and can not use even ACR 9.1.1. For Photoshop features CS4 is likely fine, I've used it and CS5 too. Thing is most Pentax cameras have two types of Raw, PEF and DNG. There is only one DNG as far as I can tell, conversion to it is a different matter.

Adobes standalone dng converter will do what you want. It's a little different from adobe camera raw and photoshop.

ACR version is limited by photoshop compatibility so it can only handle a certain number of input formats, the A6300 raw file format came out after the version of acr that you can use with PS CS4.

The DNG converter has had many releases each one supporting more camera raw formats than the one before but pretty much having the same output format dng. dng has had a few versions released too but you can specify which dng version you want to convert too.

For PS4 You probably need to open the preferences in the DNG converter and change the compatibility to Camera Raw 4.6 and later.

Thats as close as a universal raw file as you are going to get.

some sensors produce 12 bit pixel data some 14 bit (maybe in the future 16 bit) Ok maybe you could store 12 bit data as 14 bit data it wouldnt be very efficient but perhaps you could. So everything gets stored as 14bit but then a new sensor comes out which has 16bit data are you going to throw out 2bits in order to be compatible with the 14bit format you mandated? There usually is a change of format with each camera model released in practice.

Can you see why it might not fly to make all raw files the same.
