For some reason this is the 3rd installment of the curse of the film camera era.
This article is about "development".
Since we talked about RAW development itself in May (→ related article), here I would like to talk about the language confusion caused by the curse of the film camera era.
Even now, I often see and hear the phrase "develop digital camera photos". When I read the context, it seems that "printing a photograph" is called "developing".
This is an obvious mistake, but it's also annoying that I don't know why such a mistake has become established.
When I googled "development" because it was fixed, I got this result.
A few advertisements hit at the beginning, but there are words such as "5 yen per photo / photo development" and "3 yen per photo development".
I googled for developmentThe usage of this "development" is obviously wrong, but as many people are using it incorrectly, it's wrong for advertising to be a hit. I guess he's using it on purpose.
Actually, when you click on it and jump to that site, the word "development" doesn't come up. It is commonly referred to as a "photo print".
In the site, it is called "photo print" instead of "development"So why is print called "development"?
In the age of film, you can't see a picture just by taking it. Furthermore, if the film is exposed to light even after shooting, it is out.
First, it is necessary to process the film that has been photographed with chemicals to bring out the image, and fix the image. This series of processes is called "development".
Top is undeveloped film, bottom is developed negative film. By the way, don't expose the above undeveloped film to light like this. This film can no longer be used due to equipment trouble. Then) it is inconvenient to browse.Usually, at the same time as sending it to "development", I also have it printed on paper.
It is called "simultaneous printing" because it is printed at the same time as developing, but ordinary people do not only develop (ignoring this for non-ordinary people). I always order prints, and it's the prints that I actually enjoy.
Therefore, "sending the film to development" = "development + printing", and before we knew it, "developing" ≒ "printing".
I understand that feeling, but it's quite confusing to be told to "develop" a print of a photo taken with a digital camera. Value your words as much as possible.
Then, when asked if there is no "development" for digital cameras, there is. However, I borrowed the word "development" from film because I am used to it and find it convenient.
The process of taking pictures with a digital camera is like this.
Press the shutter.
Then the image sensor receives the light and converts the signal emitted from it into digital data.
The converted digital data is subjected to image processing such as matching the white balance, adjusting the contrast, sharpening the details, reducing noise, etc., converting it to a JPEG image and saving it to the recording media.
Then, we view the image on a camera monitor, smartphone, or computer.
The process of converting the digital data taken in this camera into data that can be viewed is called "development". It's confusing, but it can't be helped because that's what they call it.
The digital data before development is called raw data and is called "RAW data", and the process of image processing the RAW data to create the final image is called "RAW development".
Most digital cameras can save RAW data as is, but while JPEG is a standard format determined by the standard, RAW data is stored in a completely different way and extension depending on the manufacturer. Since it is incompatible data, it must be converted to a standard format image such as JPEG in the end.
RAW data from each company. Each extension is different. DNG is a format for RAW data developed by Adobe. We are trying to standardize the RAW data format, but we are using PENTAX and Sigma (Sigma can choose between its own X3F or Adobe's DNG)In that sense, it is a film The work of developing and making it visible and the work of developing RAW data and saving it as JPEG that can be viewed on any device are similar.
