alot has changed since i first used a camera in the preliminary task.....

As we can see the use of camera has changed and many more techniques have been exhibited, with the preliinary task i was a amatuer and very weak as i hav never used that before , the cannon 500 is a very techy piece of equipment which could only use to very basic amount when filming the prelim, i didnt know how to use many different features such as white balance.
another technique on a piece of software is final cut pro that i used in my thriller that i didnt use in thethe prelimanary task is the fade and cuts as as when  using the final cutpro earlt on istruggle the use of the software which lead to a jumpy and lack of continuity editing when watching the prelinminary task.
Another feature that was apparent in both product was the use odf sound effects and back ground music with the preliminary task we didnt know howto contro the sound effects andplace them more accurately to what i was trying to portray,whereas i was more specific in placing the the crow sound effect in my last product , as sound was a crutial feature that was highted the final product.
