Raw vs Jpeg in Photoshop

There are two primary formats that are used in digital cameras which are RAW and JPEG. It is really confusing as there are lots of different flavors of RAW. RAW actually belongs to generic term that people use to describe the unprocessed data that camera captures.
For example Nikon's RAW format is .nef and Cannon's RAW format is .crw but the file formats are all very similar and they contain much of the same information such as  metadata about the camera settings and information about the image but there is no way standard way to writing them. So each manufacture has its own unique order to the data in the raw file.

Raw vs Jpeg - The Difference

Now there is one RAW format that not preparatory is in DNG ( Digital Negative format generation ) format and many people convert there RAW files into the DNG formats because of the facts that it was openly documented file format and there is a hope that the files will be opened further into the future then if there kept in a preparatory format.



Now Adobe Photoshop is the creator of the DNG file format. The important thing that you should know if you compare the quality of the RAW format vs Jpeg there are lots of information in a RAW file. RAW file is unprocessed as a result you can make greater changes like colors or tone ls values in a RAW files with out losing  image quality.
The JPEG file on the other hand has already been processed and that includes having compassion which the roles away the data applied to it and it process applied the camera so you can make it a dramatic exchange to a JPEG file out losing quality.

Conclusion for RAW vs JPEG :

RAW is a great format to post process your images, it contains alot of information, while JPEG is a compressed image format which eats up the quality of the image reducing the size.

How to Add Metadata in Adobe Bridge

In this tutorial you will learn how to add Metadata in Adobe Bridge. As our collections of images grows, we have to embed information about in image in the file itself. This information generally refers to its metadata and some metadata is actually added automatically for example when we use a digital camera to capture an image, the camera manufactures includes information such as a lens that was used or the location spot. We can also add our own information in the file within a minutes. Lets take a look for adding Metadata in Adobe Bridge. In Adobe Bridge the best way to see Metadata of single image as well as bulk of images is via Metadata panel. If we want to see more information, first we choose any image from the main page and then double click on the Preview in order to minimize this panel.

Tools used to add Metadata in Adobe Bridge

When we minimize the Preview Box we see that there are more option coming up below Metadata section including

• File property
• IPTC Core
• IPTC Extension
• Camera Date
• GPS
• Camera Raw
• Audio
• Video
• Dicom

All these features are used to add Metadata in Adobe Bridge and you can easily customize your desired image metadata and keywords. If you want to add some more information about your image then Go to Tools > Append Metadata or chose Replace the Metadata. The difference is if you already had some Metadata as signed in your image and you just want to add more Metadata to it you can use Append Metadata. For example if you already add some Metadata and copyright information of your image but you want to add secondary information about your image like where to use this image, resolution of image or you add a caption then we use Append Metadata tool. Or if you already done with Metadata but want to replace some values then use Replace Metadata Tool. This is how you add Metadata in Adobe Bridge for your personal blogs, clients websites or in your projects.
