Parrot Bebop 2: photography without secrets

There are 3 types of “photo mode” in the Bebop2’s settings:

– JPEG SNAP: it takes a screenshot of the video stream at a 1920×1080 pixels resolution. The image quality is not so good because of the video image stabilization that tends to remove sharpness and accentuate edges. What you get is what you see.

Aqueduct

– DNG(RAW) : This mode takes a raw picture at 4096×3072 pixels resolution in a DNG format. To use this picture you have to use softwares like Photoshop or Lightroom. What you get is NOT what you see.

Drone_024

– JPEG 180°: it takes a fish eye shot at a 4096×3072 pixels resolution..the same as DNG, but there are small editing possibilities.

– JPEG : it takes a fish eye shot at a 4096×3072 pixels resolution…but its fisheye’s distortion is not completely correctedWhat you see is SIMILAR to what you get.

With some work on Lightroom we can adjust the DNG:

Here is the steps:

scr1
scr5

Important step: the crop. Here we loose a lot of pixels because we have to obtain a horizontal picture from a vertical one.

scr2
scr4
scr3

I wonder because the format of DNG in vertical and not horizontal…like others camera..i.e. a Gopro.

Here there are other samples of the various format of the Bebop 2’s camera. I took the pictures from various distance because “what you see on the display” is very different from “what the drone sees”.

In front of the house..see the differences between JPG and JPG SNAP

DNG

Drone_001

“Corrected” DNG ( we are very near and the lens distortion is difficult to correct )

Drone_002

JPG ( no lens correction)

Drone_031

JPG SNAP ( the part of the house that we see it’s very different from the on of the JPG above!! )

Drone_004

 

On my opinion the best solution to take home a good photo from the Bebop2 is to snap with all the different “photo mode”. As you can see sometime there is a very big different from what you see on video and what the drone sees…

After Lightroom my X100T camera settings (for street-photography)

Shooting Menu

Instant AF Setting -> AF-S : because AF-S it’s better than AF-C, and this is true for all the cameras.

AF Illuminator -> OFF : in Street-Photography it’s important to be invisible!

ISO Setting:  ISO it’s important like Aperture&Shutter. I use the camera in Program Mode and using the following ISO setting I’m sure to have a correct/good exposure every time (almost!), in any case it’s fast to change the exposure ( with the X100T).

  • Default Sensitivity -> 200
  • Max.Sensitivity -> 6400
  • Min. Shutter Speed -> 1/125

Image Quality -> Fine + RAW : I have a ready&usable JPEG (see below) and a RAW file for Lightroom or Photoshop.

Film Simulation -> Classic Chrome : I like this Chrome very,very much!!

Color -> +1 : I like satured colors but not too much, +1 it’s good.

Sharpness -> +1 : it’s better to have a good sharpness.

Photometry -> Multi ( Spot: if I have time to decide exposition. )

SET-UP Menu

Sound Set-up: ( remember to be invisible…and silent! )

  • Operation Vol-> OFF
  • Shutter Volume -> Minimum

Color Space -> Adobe RGB

 

A prehistoric photo

Today I took a prehistoric photo with a prehistoric digital camera: Canon Powershot A100

canon

Yes I said “prehistoric” because the A100 was produced in the year 2002 Wikipedia. So .. 14 year are like 14 centuries in the technology life ( not humanity’s life! ) … ore more?? Then I took the same pictures with a “modern” Fujifilm X100T  ( I used the quotation marks because the X100T was born in the 2014 .. )

fuji

Here you can see the two pictures ( edited with Lightroom, but only to adjust ( a minimum ) contrast, saturation and sharpening :

Canon Powershot A100

Fujifilm X100T

In these small size we cannot see a lot of differences..to be “human” I set 100 ISO in both of them 🙂 🙂

The “surprise” is on the details…. Can you figure out which is the X100T? 🙂 🙂

The fundamental question of (digital) life

JPEG or RAW ? How many times I heard this question!! Who is the winner? And the Oscar goes to ….  the answer is: it depends! There is not a winner. Both of them have pro and cons… I don’t want to publish a bare standard table with pro&cons but I want to speak about real-life samples. Generally speaking RAW has a lot of pro…but..

I.e. I’m a professional sport photographer and during a race I shot hundreds of pictures and I have to choose and send them to a newspaper as soon as possible. So I have not time to convert/edit them from RAW to JPEG (remember that a RAW file is very-very large )…so I use JPEG but I set my camera to give me a good JPG: i.e.  adjust contrast/saturation/white balance/size. Some year ago I attended to a workshop held by Ivo Saglietti  and he said us to use only JPEG: the reason was that we have to concentrate only on the composition of the image and not on the editing.  Here my reportage in JPEG.

On the opposite I have time to edit the RAW…so I want to work in photoshop with the most quality of my pictures. Here the advantage of RAW is that I can edit/correct the file without big reduction in quality. Remember that everytime you save a JPEG file the software , that you used for editing, reduces it!  Yes! It’s the definition of a JPEG file: a compressed file with loss of quality ( also a ZIP file is a compressed file…but the compression is lossles: we can restore the original file). In the case you are using a JPEG file, my suggestion is to to save it in the default format of the software you are using: i.e PSD for Photoshop. So the next time you edit and save it, you will not have quality reduction.

This is not an advertising! I have a Sony RX100M3 and if I want a good JPEG picture I can set  on of  the Default Scene ( i.e. Sport,Landscape,Sunset …. ) or the Superior / Intelligent Auto mode. In my next post I’ll show some pictures in those settings ( versus and edited RAW).
