Why & How are some photos BMP instead of JPG?

Question

what makes a pic become Bitmap and not jpg??

Answer 1

BMP (bitmap) and JPG (are two different formats altogether, much the same way as a poster is not a photograph and vice versa. Although both look roughly the same, they are made of different "materials"

BMP is the native image format for Windows. It's a medium resource, no-compression format. This means while they can contain decent pictures, they are very large.

JPG is a low-resource, high-compression format. It's designed for using actual photos on a computer without taking up a lot of space. JPG images are usually created with actual photo/graphic creation software such as PhotoShop.

You'll also eventually notice other formats such as GIF, IMG, PNG and others. Each type has it's strengths and weaknesses, and each one was designed for a specific need .

.bmp (Bitmaps) are actually larger, less compressed picture files that the typical .jpg. The user selects whether he wants to save an image as a .bmp or a .jpg unless the camera itself chooses for him/her. You can convert one to another and back and forth, but the more compression you have in a photo, the less control you have to edit it, and usually poorer quality. Shooting in RAW mode is best, but most amateur won;t kwno how to edit or make a RAW image usable for print or web posting. It's important to know that most websites use the .jpg format so unless you're in the bisuness or have a specific need, you should just about always use a .jpg (even though it's highly compressed). I figured if you have a real need to use a .bmp or RAW formatted photo, you probably already know enough that you didn't need to look at this question. Good luck!

Answer 3

BMP is a diffrent format for the file, so it is saved in a diffrent way. To change it in say paint, when you save and it says "Save file as:" click bmp for bitmap or jpg for Jpeg, When you save it as jpg you loose alot of the quality. BMP is less supported, but the pictures look nicer.

Answer 4

It is just the compression method used. There's many applications out there that can convert BMP to JPG, same as applications that can create different compressions (such as Adobe Photoshop)

Quality wise, it depends on the compression on JPG. If you use a quality 8 or higher, its better than BMP and also takes less space.

Answer 5

People that are still using BMP files just don't know any better. My mom sent me 10 pictures of their new dog, and the mail was about 7megs! Ridiculous! Anyways, I ended up showing her how to convert BMP files to jpegs, and explained to her why she should use jpg as standard. So go out there and let people know. Soon it'll disappear. :)

Answer 6

you are able to in basic terms replace the record extension on the record names, yet your laptop gets at a loss for words with regard to the record style. the the perfect option thank you to do it extremely is in a picture application -- do 'shop As' and alter the record style. in case you prefer to alter a great style of documents there could be a 'batch' selection so you might technique distinctive documents on the comparable time.
