Self Portrait

We had to draw portraits of the partner you picked to do it off. Just before that we had to do research into the structure and muscle in a human face. To do this we were given a sheet with the human face showing the muscle and skull. 

There were 22 muscles and bones we had to research for this. This is the sheet we were given. 

After that research we had to draw our partner. I drew Sirian, the main thing I concentrated on was the main face shapes also the detail in the hair. I learnt to do quick detail in the hair through looking at tattoo techniques on tattooing a portrait. I also looked into the main shading parts on the face and I didn't have time to draw it in full detail but I made sure it was blocked out and could be seen. 

Tomorrow we will be researching photography and that will lead onto portrait photography. I learnt that taking a 'selfie' doesn't show the true image, this is down to image distortion, in other words pixel distortion, this is why you may find a selfie will look very different to a photograph taken from a camera.

This clearly shows the difference of a selfie camera on different phones let alone the difference of it being on a front camera. I did research into what selfie camera people most prefer and it's the iPhone7 it has been proven that its most accurate to a front view camera.


What is ISO:  

ISO is the level of sensitivity of your camera to light around in the area at the time. The lower the ISO number, the less sensitive it is to the light, while a higher ISO number increases the sensitivity of your camera. The component within your camera that can change sensitivity is called “image sensor” or simply “sensor”. It is the most important part of a camera and it is responsible for collecting light and transforming it into an image. With increased sensitivity, your camera sensor can capture images in low-light environments without having to use a flash. But higher sensitivity comes at an expense – it adds grain or “noise” to the pictures.

       As you can see the difference in the photo when the colour of the camera is boosted up.

Every camera has something called “Base ISO”, which is typically the lowest ISO number of the sensor that can produce the highest image quality, without adding noise to the picture. Some older Nikon DSLRs and a number of other modern cameras such as the Fuji X-T2 have a base ISO of 200, where as most modern Nikon and Canon digital cameras have a base ISO of 100. So, optimally, you should always try to stick to the base ISO to get the highest image quality. However, it is not always possible to do so, especially when working in low-light conditions.

Typically, ISO numbers start from 100-200 (Base ISO) and increment in value in geometric progression (power of two). So, the ISO sequence is: 100, 200, 400, 800, 1600, 3200, 6400 and etc. The important thing to understand, is that each step between the numbers effectively doubles the sensitivity of the sensor. So, ISO 200 is twice more sensitive than ISO 100, while ISO 400 is twice more sensitive than ISO 200. This makes ISO 400 four times more sensitive to light than ISO 100, and ISO 1600 sixteen times more sensitive to light than ISO 100, so on and so forth. What does it mean when a sensor is sixteen times more sensitive to light? It means that it needs sixteen times less time to capture an image!

ISO Speed Example:
ISO 100 – 1 second
ISO 200 – 1/2 of a second
ISO 400 – 1/4 of a second
ISO 800 – 1/8 of a second
ISO 1600 – 1/15 of a second
ISO 3200 – 1/30 of a second

In the above ISO Speed Example, if your camera sensor needed exactly 1 second to capture a scene at ISO 100, simply by switching to ISO 3200, you can capture the same scene at 1/30th of a second! That can mean a world of difference in photography, since it can help to avoid camera shake or motion blur.

How to know what F Stop to use

Photography deals with capturing light in a way that appeals to your artistic ways, whether you prefer perfectly-lit, tack-sharp portraits worthy of presidential candidates or blurrier, artistic renderings of NASCAR competitors roaring by at 180 mph (290 kph).  F-stops in particular have a tremendous effect on image characteristics, some of which may not be obvious to amateur shooters. For the bulk of this article, we'll discuss and improve your grasp of the mysterious f-stop.

Shutter speed

Shutter speed, also known as “exposure time”, stands for the length of time a camera shutter is open to expose light into the camera sensor. If the shutter speed is fast, it can help to freeze action completely, as seen in the above photo of the dolphin. If the shutter speed is slow, it can create an effect called “motion blur”, where moving objects appear blurred along the direction of the motion. This effect is used quite a bit in advertisements of cars and motorbikes, where a sense of speed and motion is communicated to the viewer by intentionally blurring the moving wheels.

The difference between RAW and Jpeg

RAW file is basically an image preserves most of the information from camera, such as sharpness and contrast, without processing and compressing. However, RAW format need to be converted to JPEG and other image formats which are more convenient for printing and sharing.

JPEG file is a commonly-used image file format, which will be processed and compressed by the capture device according to the settings made by the user before archiving. It is a very popular image format, and can be easily opened in most computers. The users can freely set the compression level to preserve the quality for their JPEG files.
