Lens distortion m2p

[Andrea1976]

Hi everyone
Have you noticed the big amount of lens distortion shooting raw photo? I use affinity photo and I guess that the lens correction panel doesn't make a great job.. the horizon corrected isn't perfectly straight.

As soon as I can I give you an example

Bye

So far I haven't encountered lens distortion.
The fact that you are shooting RAW won’t or at least shouldn't make any difference to any distortion.
I tend to shoot RAW & JPEG simultaneously and get no difference before post processing.

look at that.. note the horizon. when I make lens correction the horizon appear curve in the center.. isn't strait at all..

cheers

I thought the earth was round, not flat!
M2 can only capture what it sees!

ok I shouldn't take picture from the stratosphere..

Affinity Photo doesnt correctly read the lens correction parameters from the DNG file hence the distorted images.
Not all image editors fully and correctly implement the DNG protocol, Affinity is one of those.

Other editors such as Adobes ACR etc will read and apply distortion correction so the image is straightened (and obviously slightly cropped).

But to back to the OP. The camera has terrible distortion when you take it off center i.e. look up or down. Look up and the horizon edges will curl up and looking down they curl down.

It’s too bad DJI did not allow for the portrait orientation like the MPP has.

As has been already mentioned ACR/LR show the files with the lens corrections applied and you can not remove them. File is cropped considerably on edges.

Capture One allows you to see the image with the built in profile but you can use a generic setting which allows you to see the entire image albeit with the distortion.

I would rather manually correct the distortion so I use C1.

Also I find C1 has better edge details than ACR with the generic profile.

DxO Photolabs 2 has an M2P lens profile which corrects distortion.

Of course shooting in raw means distortion isn’t sorted as this is only fixed when converted to jpeg by the camera - be it a terrestrial camera or one fixed to a drone.

Actually the correction is baked into the DNG by default. But yes its 2 stage, its raw and correction information bundled together. Most programs that properly implement DNG (and lets face it, its an open source, documented format) will splat both together for editing although it is possible to manually stop it being applied (or even remove it).
Its not a JPG only thing as such. Of course, we dont actually *get* raw files on the Mavic 2. A DNG isnt a raw image.
Mavic 1 was worse, in some cases, especially on earlier firmware it was applying sharpening,contrast and other style settings to the DNG file.

Thanks for the clarification. DxO certainly applies further correction to the DNG file. I’ll post a before and after tonight. It’s subtle but noticeable.

You'd expect that. Obviously its a compromise - the more you fix distortion the more you end up having to crop (and/or affecting corner sharpness). Where that compromise is made is down to the actual software coders making the raw converter. The DNG gives them all the information they need to implement it but the extent to which they remove distortion is up to the writers.

DxO are the masters of lens correction as far as I am concerned. They have profiles for pretty much all camera/lens combos and apply them very well.

Yep DXO are very good optics wise. I just wish their end user software was on par with the others.

I really like Photolabs 2 - works very well. Just takes a bit of getting used to and yes then work flow is somewhat different to LR.

Ok, thanks everyone for the info. I'm not a professional user, I don't make film or photos as a job. I just felt in love with aerial context. What do you suggest to optimise my workflow in post? Shooting in jpeg I suppose! And all the marvellous raw things? I just made peace with the d-log color profile using proxy in fcpx (300 bucks!) I'd like to get the best from the m2p without compete in the Scorsese award!

Ciao!

Always always RAW. Theres no point buying a M2P and using it for JPG.
You just need better image editing software that can actually read the distortion data (if you dont want to self fix). Lightroom/Photoshop/Capture 1 and others do it.
