Apple focuses on professional camera features. New iPhone 15 Pro and Pro Max during this week’s launch event.
In fact, Apple has removed so many concepts, terms, and acronyms in such a short period of time that it might make your head spin.

do not be afraid. Now that we have a moment to catch our breath, let’s review these features and explain their importance.
Let’s start with the information dump on this one slide.
Focal length is an abbreviation used to describe the width of the image that a camera lens captures. The smaller the number, the wider the capture range.
Technically, this lens isn’t a 24mm lens, it’s a 24mm equivalent lens, but you’ll miss that.
2.44μm (micron) is the size of the pixel that captures light on the sensor. quad pixel Refers to the way four pixels are grouped together to function as a larger 2.44 micron pixel.

One color is assigned to each 2×2 group of pixels, and four of these pixel bundles are grouped into two green bundles and one blue and red bundle. The human eye is most sensitive to green colors, so green will get more pixels.
100% focus pixel It means that every pixel is used for the purpose of focusing the image. Previously only some pixels were used, but now it is common for high-end sensors to use all pixels.
aperture It refers to the amount of light that is incident on the sensor by the lens and is measured in units. F value numbers. The lower this number, the more light the lens lets in.
OIS Optical Image Stabilization is a technology that shifts the lens or sensor to compensate for camera movement during shooting.
Other terms removed during the event were: Living and ProRAW.
You can think of RAW as a digital negative (remember film negatives?). This is a file format that saves the raw data captured by a sensor without processing it or converting it to a file such as a JPG. RAW files are larger and contain more detailed information, but require editing before printing or posting to social media.
ProRAW is an Apple file format that uses the industry standard digital negative (DNG) file format, allowing files to be edited with high-end editing tools such as Adobe Lightroom.
Also, what is ProRes and why does Apple keep mentioning it?
Another frequently used term was optical zoomThis is a technique where the image is magnified by the lens itself. digital zoom, This simply crops the image, resulting in loss of detail.
There is also that HDR, stands for high dynamic range photography. This is a technique that combines multiple images into one image of her to get details in highlights (bright areas) and shadows (dark areas).
big Photography is about getting close to a subject, such as a flower or insect, and taking a close-up shot.

Now, on to the video — the first thing I need to explain is: wrestling.
Apple talks a lot about ProRes because it’s a video codec (short for encoder/decoder or compressor/decompressor) developed by Apple. Dating back to 2007, ProRes is special. The reason is that when you compress a video, this compression always results in the loss of some image detail (this is often referred to as “lossy”). This missing image detail is not visually noticeable.
In other words, ProRes is a visually lossless and lossy video compression format.
The disadvantage of ProRes is the larger file size, but it is much easier and better to edit.
To alleviate the huge storage needs that ProRes imposes on videographers, iPhone 15 Pro supports recording to external drives. Samsung T7 SSD — This means there is no limit to the amount of storage space available on your iPhone.
Two other technical terms sprinkled throughout the on-camera coverage were: log encoding and LUT.
Log encoding is a profile that records video with a flat, muted color profile to capture and preserve highlight and shadow detail. The iPhone 15 Pro is the first smartphone to support ACES, the Academy Color Encoding System.

The disadvantage is that this format must be edited before it can be used, and one of the editing steps is to apply a LUT (lookup table). A LUT is a file that contains information for remapping flat footage to transform it into color and colored video. You can adjust the contrast and further edit it to suit your desired style.
Editing Log-formatted videos and using LUTs requires specialized tools, such as: adobe premier pro.
I hope this overview is helpful to those who are confused by some of the terminology used. You might even be able to encourage them to get a little more creative or technical with their photography and videography.
