- Pixel – a single point in a raster image, it’s the unit of a picture that can be shown or manipulated
- Raster image/bitmap – a data structure usually a rectangular of pixels
- Resolution – describes the detail an image holds. 72ppi is used for most computer monitors and 300dpi is used for printing.
- Lossy Compression: compresses data by losing some of it.
- JPEG – a common method of lossy compression. Used for everyday and internet use.
- TIFF – used for storing large and high quality images. Used for large quality printing.
- PSD – photoshop working file so one can save all their layers. Used for large scale editing.
- RAW – not yet processed data from a digital camera. An original file.
- PNG – Huge files that can retain transparency of a part of an image or file. Specialised for web use.
One cannot enlarge an image once it has been reduced.
Non Destructive Editing:
The term refers to editing techniques that allows the original content to be preserved but also changes can be made. For example layers can keep the original photo when you can also make change.
Always back up your data. Use a good quality memory device and always keep the original photo or file. Save the file as you go along so if something happens you have a backup.
Also have separate folders so RAWs and JPEGs or originals and manipulated.
Browser Software: helps you look at photos to decide which photo you wish to edit.
Photo and Design Composition:
- Rule of Thirds – balances photos. It breaks an image into thirds both horizontal and vertical. The points of interest on a photo should fall where the lines meet or on the lines.
- Lines – makes a photograph more interesting. Vertical lines give the idea of power, strength or growth. Horizontal gives the conveys the idea of stability. Diagonal lines makes the photo more interesting and dynamic.
- Filling the Frame – you can manually in post production do this but you need to remember that after cropping so much a photo will become too small to see.
- Focal Point – where your eye rests. So these could be where the photo is in focus, a certain texture, size or shape in a photo. Also blur, colours and position can attract an eye to a certain part of a photo.
- Backgrounds – make sure distracting elements are removed, blurred backgrounds, place subjects in front of open spaces, fill the frame or make your own background.
- Breaking the rules – sometimes it is good to do so but remember it still has to work.
- Alignment – creates a sharper more ordered design. It can create a visual connection.
- Repetition – can strengthen a design by tying together individual elements.
- Contrast – when two opposites come together – doesn’t have to be colours, could be sizes, lines or fonts.
- Proximity – can create organisation, grouping similar elements together creates a relationship.
- Balance – provides stability and structure.
- Simplicity – knowing when to stop don’t make an image too distracting
How to edit out certain parts of an image:
These images belong to Iris Aperture
Either use the dodge tool or the clone tool.
The clone looks like a stamp, you click on it and click alt and select the part of the image you wish to clone, then only click on the area you wish to remove.
The dodge tool one can use when they click on the dodge tool, the symbol looks similar to a lollypop.
I also adjusted the levels (increased the black to 9). I also used the burn tool to darken the shadows of her eyelashes and darken her eye makeup
