Telephoto lens query Air 3S

Questions & Answers

Good evening Gents,

Just a quicky about telephoto lenses and images captured :thinking:.

When I take a snap with the tele x 9 on the 3S, obviously I can see what I’m getting on screen when I set the shot up, or do I? :thinking:.

Took a few snaps today /night with the x9, bloody marvelous…or so I thought. I actually did one in post and never realised :rofl:, but it was a landscape. The image I noticed this on is a well lit pub near us at night, so a high contrast image. I had zoomed right in on the pub framing it nicely, just to see how it turned out and what could be done in post.

In post, throws the said file into LR and I thought I’d got the wrong image. It was zoomed the f#@k out :face_with_symbols_over_mouth:.

On opening the file I’d loaded into LR and comparing what was in LR on me other monitor, well, I’m totally miffed.

Why do I have to crop into the image in post, just to get what I should of got when setting the shot up? What’s the point?. Please somebody explain, before I book a flight to DJI land an shove the damn drone (also with shitty night shots and a qhad Bayer sensor instead of full), right up Dji’s arse.

Rant over :hot_face:, here’s the files, if somebody could please shed some light on the situation.

And I know before some smart bollocks mentioned it, I actually did say quicky at the start. :rofl:

I just opened it on my I phone as I’m not near my computer,
On saving the image & opening it is zoomed in,

But when I go to edit it, it shrinks down,

Exactly, or sooms out. Why though🤷

It’s it not because its a digital zoom, so what you are seeing on the screen is just a cropped image

When you take the picture it saves the whole image so you can zoom/crop in post

I get that after thinking about it, but why make it that way. Misleading. What the drone should take image wise is whats displayed on screen at time of taking it.

It takes up more time, more space.

So, am I actually taking a 9 x zoom image at the end of the day?.

I’m off to do some more shots later on with this and see whats what

But that’s just a low res-cropped image

In post, you can do more with the full res uncropped image

Pretty sure were you shooting in JPG then WYSIWYG.

I know what your saying, and I know you can do much more in post with a hi res version, but really, it doesn’t make sense to me that the image what you get has surrounding content to the image you framed.

Like I say, I’m going to do some snaps later on with different states of zoom and see what comes out👍

WTF?

What you see is what you get.

I thought I had read somewhere that a jpg of the zoomed photo is kept somewhere,

Arr right. Don’t know about that. Gonna have to do some digging around on Google, but there ain’t much on the 3S at the moment, never mind the camera.

When you shoot in RAW, it saves a dump of the full sensor data.

If you want to use a digital zoom, shoot in RAW + JPEG or crop when pp’ing the image.

I raised a similar thing about the Mini 4 pro.
Likewise i thought a Zoomed Raw will give what I saw on the screen in the end file.

AFAIK, RAW will always just save the sensor data. This is the same as even my DSLR.

The digital zoom is simply the central part of the image as seen by the sensor - the zoom is literally just making the center bit larger.

On my Mini 4 Pro, JPG saves “what I see”, while RAW does not.

I noticed too, that Air 3S will not always save “final” images, for example, it will auto-stitch and save 180 panoramas, but the other modes just save the panorama as a bunch of files I must manually stitch later.

All been dead helpful :+1:. I do understand the thing behind it now, just don’t understand why the image on screen can’t be calibrated to the same as the image you get. Christ, all the things DJI do with software and they can’t sort out something like that​:thinking::smirk:.

Yours, never happy​:triumph::rofl:
