P: Include ruler (measuring tape) in pictures based on exif

[louisd79464044]

Pictures used creatively may often disguise the actual size of the objects. In art that is the tool applied but in there are subjects like pictures of animals, flowers or even buildings of which the actual size may be usefull to know. Especially science, but also forensics may be served by it.

Modern camera's have the object distance, focal lenght in the exif, and the camera characteristics do include the image distance + chip size, so the size calculation and visualisation of the object focussed on in Lightroom and Photoshop is an opportunity to include relatively easily.

For me as a biologist, not enjoying addition of a measuring tool in the picture (and miss the living object because of  that), and considering the technical data is already available in most modern camera's producing RAW files, am wondering if Adobe is supporting this idea and open to the opportunity to launch such first in photography apps land.

In fact I did actually make a calculation spreadsheet to calculate such myself, so how easy can it be to have the scoop in Adobe novelties?!

Hope I find some enthousiasts in Adobe .

The chip size is not part of the EXIF ​​data, nor is the image distance. To get the chip size it's possible to get the camera type. Then you need a database with all camera types of all manufactures which includes the buildin chip size.

For the image size I'll see no chance to get any informations.

So I think it isn't possible to calculate the real size of the object.

Thanks Axel,

I do not agree. As said I actually made a spreadsheet for the calculation myself. But that is actually timeconsuming to work with because I need to measure the object on the screen and manually put the dat in the sheet.

Indeed the chip size is not part of the exif data but there are only few (about 10) standard sizes used in the camers sold today. See: https://en.wikipedia.org/wiki/Image_sensor_format. . So if it is added as a presetting (dropdown choice) in the PS or LRc menu should be sufficient to enable the calculation when the exif data include the object distance (i.e. focus distance)..

You are right that making a list of cameras in e.g. Camera Raw would be quite a job and would take updating needs too.. 

So, I see no problem to keep it simple.

Cheers,

It's nice that you don't see a problem, but you're making it too easy for yourself.

As far as I know also the focus distance isn't really include in the EXIF data. Some camera estimates the distance and records it in EXIF, but not all cameras record the distance in EXIF.  Also not all estimates of it are correct. 

So this informations, if the camera wrote this in EXIF aren't helpful.

I don't know anybody that needs such a function and the effort is far too great to implement such feature.

Hi,

The reason you do not know anyone that needs such a function is because science and reality have presently been moved to the background in the modern society of AI and free internet applications where facts are neglected by any personal input/opinion. One of the major advantages in photography is the artistic opportunities it gives for playing with relative sizes and as such 'changing reality' or use the way our vision can fool our observation/brain. Actual size of the object shown in a picture, like used and needed in police investigations, and also in science, architecture etc. seems to have become less important in the present society, like the original goal of internet has fainted. (i.e. internet was meant to make science more available for anyone, but most publications are now commercially blocked by publishers). But in practice (e.g. in scientific applications and security) it is even more important nowadays to keep control on our society 'ruled' by smartphones and the internet. AI is taking over reality more and more, but if we loose the opportinity to see the reality behind AI we will loose the link to reality and the facts needed to preserve reality in our raw pictures.

OK, if ADOBE prefers to serve the artistic value more than keep the way to scientific reality included, please realise that it is a choice you make.

Louis
