Week 12: Day 2 of Work Experience at LIT
Week 12
Day 2 of Work Experience at LIT
***I have finished up on the tasks given. In between now and the next task I'm increasing my knowledge of key design areas.***
Photoshop:
Watching Lynda.com video tutorials on Photoshop this morning. This video tutorial shows how to open images in Adobe Bridge, send to Adobe Camera Raw, make adjustments there and then send to Adobe Photoshop to develop further. It is about workflow in this way.
Noting some key points as I go along the video:
Customizing colour scheme:
It shows how to customize settings including colour scheme in replacing the default sRGB with Adobe RGB, which provides for a much wider range of available colours. There is instructions on Preferences settings here (Edit->Preferences...):
a. Interface.
b. File Handling.
c. Performance.
Customizing a Workspace:
window->workspace->select e.g. Photography.
Camera Raw for raw images i.e. not jpeg etc.
Raw processing in Camera Raw is a not destructive editing process, where the original and subsequent changes stored in layers can exist.
To go from Adobe Bridge to Adobe Camera Raw: files->open in->camera raw.
Camera Raw->Photoshop:
In Photoshop action_1:
This next technique can be used to, for example, remove elements in the background of a picture you want to delete/hide.
Steps:
1. Create and name new layer.
2. Use "Ctrl+j" to select the "Healing Brush Tool."
3. Use this brush tool to paint over areas you want to remove from the image.
-Also, at this stage, adjustments can be made such as using the "Balance tool," where a change made in one layer can be replicated in all other layers.
Opening and then Importing lots of images:
For Raw images: double click on image in Camera Raw-> opens in Photoshop.
or-> File->Open->Open in Camera Raw.
For e.g. JPEG images: File->Open->Open in Camera Raw.
To return to Adobe Bridge, and not stay in Camera Raw:
-click the "DONE" button in Camera Raw.
To view previous images click "Ctrl+P" (on toggle).
Opening, saving and closing a photograph:
a. Opening: select folder->select file->at base of screen in "File Format," select "Camera Raw," and make adjustments here->then click button "Open Image"->and it sends the file over to Photoshop.
b. Saving: save->file format as either "Photoshop" or "Tiff" as both of these support layered files. Also, check the box for "Embed Color Profile," which helps for color access->click "Save."
When saving check the "Layers box."
File->Browse in Bridge->Select Image->double click on image to open it in Photoshop. To view in Adobe Bridge:
Closing from Bridge:
Use the boomerang symbol at top menu for this and brings you back to e.g. Photoshop.
Zoom and Pan:
Use the magnifying tool (+/-), click or click and hold to zoom.
Using the pan (hand) tool.
In top menu 3 buttons:
a. Fit Screen: zooms out (space around image).
b. Fill Screen: fills screen (no space around image.)
c. 100%: brings up to 1:1 scale.
x 2 click on magnifying tool, brings up the 100%, 1:1 scale.
x 2 click on hand tool, brings up the fit to screen scale of view.
Other information:
Tips 1:
Windows->Navigator (red box can be placed over area of focus.)
To Pan->click "spacebar."
Preference tool settings:
Ctrl+Alt+O -> 100% view.
Ctrl+O -> fit-screen.
Tips 2:
To see the image without the settings screen- > click the "f" key. By keeping pressing this it cycles through the screen modes.
Hide/show panels -> "Tab" key.
Background screen colour -> right click on the background screen and select color I want.
Arranging and viewing multiple documents in Photoshop:
First-> go into Adobe Bridge, select your images (multiple)->file->open->they open in Photoshop.
To see all the images on the screen -> windows->arrange-.tile vertically.
To have all the images zoom at same time-> top menu bar->tick checkbox for "Zoom All Windows."
To have all images pan on the screen -> tick checkbox for "Scroll All Windows."

I looked up information on "Encryption" this morning so that I could learn more about it for webdesign.
These are some notes I made on this topic:
Encryption-the scrambling of data, with password access to de-encrypt for the purpose that the data is unreadable by unintended parties. Five main types:
1. Triple DES: uses individual keys at 56 bits each-though regarded as in total key length is a 122-bit strength. It encrypts data three times and uses a different key for a minimum of one of the versions. It is a symmetric algorithm. Recommended for many years and being phased out. An older version was used by the U.S. Government in the 1970’s. Used today in ATM’s.
2. RSA: public-key encryption algorithm, standard for the internet, an asymmetric algorithm because it uses a pair of keys. Here, a public key is used to encrypt and a private key to de-encrypt.
3. Blowfish: This symmetric algorithm splits messages into blocks of 64 bits and encrypts them individually. Excellent for: security, speed, efficiency and is unpatented and freely available in the public domain.
4. Twofish: is a successor of Blowfish. Keys may be up to 256 bits in length and being a symmetric technique, only one key required. Fastest in speed of its kind. Can be used in hardware and software environments.
5. AES: stands for “Advanced Encryption Standard.” Approved by the National Institute of Standards and Technology (NIST). A standard used by the U.S. Government and many organizations. Usually use its 128-bit form, and 192-bit or 256-bit for large encryption processes.
Symmetric/Asymmetric Algorithms: Symmetric algorithms use the same key for encryption and decryption.Asymmetric algorithms use a different key for encryption and decryption, and the decryption code cannot be derived from the encryption key.
The Future of Encryption: Constantly evolving to deal with and keep ahead of threats to cybersecurity. A new kind of encryption called “Honey Encryption,” is expected to deter hackers by showing different fake data for every incorrect guess of the keycode. Another type being developed is called “Quantum Key Distribution,” shares keys embedded in photons over fibre optic, for visibility.
