Capturing & Storage
A digital storage device is exactly what it sounds like a piece of hardware that stores data whether it is files documents or images and can be transported to a different computer or hardware. There are many different types of digital storage devices coming in with different sizes and use.
- SD cards are by far the most common type being used for storing images mainly it can be easily placed in to any type of digital cameras however some computers or Macs do not have an import for a memory card so you will sometimes need to have a card reader.
- These are SD memory cards but with a higher capacity (SDHC). These cards are pretty much the same but can store a huge amount of data. I highly recommend buying one of these or several f you are shooting on raw.
- These are SD cards but with a much higher capacity and faster processing speeds. these cards are top of the range for capturing images not only to the store a large amount of data but the processing speed allows you to take more images at a faster rate which can come in handy if you're shooting a wedding or a sports event where you don't need to worry about how much memory you have left.
You’ll need a card reader to transfer photos and over dater to your computer. sometimes you won't need a card reader that it is better to be safe than sorry plus card readers are normally quite cheap to buy.
The well-known JPEG is the standard for images. No matter how you what to share the photographs you are likely to use a JPEG whether it for Facebook, Instagram, Pinterest or many over social media.
Unfortunately, when converting your images to a JPEG it reduces the number of pixels and therefore reduces the amount of quality in the image. I recommending duplicating your image before changing it to a JPEG so that you have the original raw image file and your edited JPEG.
Best For: Sharing Images online with friends or family.
PSD is Is a never file format, however, this one is created in photoshop when an image has been altered by the photographer or an artist. This can be done multiple ways one way is just saving it as a PSD the other one is automatic whenever you add more lenders to your image it will automatically say is that image as a PSD to see if it as a JPEG instead you will then have two flats in the image meaning compressing the image that which does reduce the file size.
I recommend when using a PSD is to save the PSD as a separate image then flatten the image into a JPEG so at the end you have two images one you can alter in photoshop if you made a mistake.
Best For: Saving files on your workspace so you can return and edit later.
The PNG format is a lossless file type, which means it can preserve your images without any loss in image quality. The format itself was based on the GIF file type, but allows for higher bit rate pictures and can preserve background transparency while minimizing jagged edges. PNG is an excellent format for displaying images on the web that require transparent elements.
Downsides to the PNG format typically include a large file size; this means that while PNG is excellent for the web, it should be used sparingly and only when needed for transparency purposes. Overusing PNG images on a web server could result in a slower experience for end users and increased bandwidth costs for the site owner.
