Cross processing

Before
 After

Cross processing allows an images colourings to be altered, through the main use of the prime colours red, green and blue. this ends up giving an image a coloured effect to its background. If the image is sharper in red the colour a red tint will be applied, but if multiple colours are sharpened they can merge colours, in my after image i have a very sharp red and green tint, while keeping a small blue tint, this changes the white cloud in the background into a hazy explosion.

I performed this by creating a new layer and using the curves tool to allow editing of these colour tints this allowed me to change the shades of certain features of the picture making the effects on the image appear a lot stronger and powerful.

Because of these changes i have made the image appear more exciting making it appeal to a younger audience, for example if this image were to be used on the front cover of a magazine, it will connote to the audience that the magazine is more exciting and action pact, (which is exactly what the TA of a snowboarding magazine would like)

I may use an edit similar to this in my own magazine product if i can make an image look more exciting and action pact, i want to be able to do this because it will appeal to the young audience of my magazine, but on the other hand a lot of the images within the magazine are likely to be very un-animated and it would be hard to get it edited in this way to make them for exciting, so i am likely not to be using this edit type on my own product.

Shutter speeds evaluation

Shutter speed evaluation


what shutter speeds do:

The shutter speed is the length of time that the light hits the film or sensor on the camera allowing the image to be recorded within that time. Each variation in speed is best suited for different types of shots, for example a Image of a fast moving plane would need very high shutter speeds to capture the image, if the shutter speed is to appropriate for the model’s speed, it will often leave it out of focused and blurred.

why i would used a fast or slow shutter speed

A fast shutter speed is specifically used for fast moving models, such as a moving plane, the faster shutter speed the less light that is let into the shot, this allows the fast moving models picture to be taken without creating blur or losing focus.
We use a slower shutter speed for slower moving model, such as for a person walking or stood still, this allows more light to the film allowing a slower moving model’s image to be taken as clearly as possible, if this person moves faster blur can be created, this must be compensated for with a higher shutter speed.

examples of my picture: what shutter speed setting i set your camera too

The quality of the image and the problems that the image has.
The quality of the images is the worst problem when using the shutter speed feature on a camera, the camera has to be completely still to make sure the image isn't blurred to fix this i will next time you a tripod to keep the shot completely still and keep the image clear, some other issue i had while taking pictures in the shutter speed mode are:
Under exposure occurred due to a lack of light entering the camera, i to fix this i would have to retake the images at a slower shutter speed or increase the ISO speed on the camera to allow more light to enter the shot.
Framing was not a problem that occured during my time with the shutter speed feature although it is a potential problem for later photo shoots using the feature, to fix this problem in the future i will make sure to take more time to set up the surroundings of the photo shoot, i will keep them within an area large enough to fit an entire shot in so poor framing does not occur, i will also have to make sure that i keep the image in the right position by using the composition grid as this will make it easier to tell the position of the produced image
Focal blur was the main problem to occur during my photoshoot, as mentioned before it reduced the quality of the images to a point where the model could barely be seen, the best fix for it would be the use of a tripod or to make sure i got closer to my subject rather-than using the zoom on the camera.

what my targets are for taking pictures the next time
next time i use the feature i would like to spend more time reviewing how to use the feature so that i am better at using it effectively and quickly, i also want to make sure that the quality of the images are improved and i will use a tripod because the steadiness of my hands is terrible making all the images out of focus.
