i hope i am putting this in the correct category.

I set my camera (d-5100) to raw +basic jpeg to compare images.

to see what the difference between the 2 images showed. i used the landscape mode setting.

i can see a difference in the 2 images can anyone tell me which is the jpeg.and which one is the better image in your opinion. i did no post production on either images. these are straight from camera. Except for converting from raw to jpeg

Hi Norman,

This will be a nice test for me.. My thinking is that with no post processing the only difference between the two pictures is that one was converted to .jpg by your camera, and the other by whatever s/w you use to convert RAW to .jpg.. Given that I'm not sure of the purpose, but I like #2 better..

I see a little more sharpness in the first one, blacks are also darker. It sounds funny but I think 1 is JPEG, and 2 is RAW. The camera adjusts more on JPEG than RAW, but then you have more control over RAW in PP if you have a good program.

My guess is that #2 is jpeg and #1 raw. Nice photo's

Hi Edh, Image no. 1 is jpeg. I had read oh here in the past no matter what you have your auto settings on raw will not accept those settings. So i wanted to see how much difference there would be between the 2 images. I personally like the look of number 2 better as well.

Good Morning DFarmer, I have to give you the buzzer...LOL One is the jpeg.

I was just curious as to the difference between the raw and jpeg using the same auto settings and wanted to have a little fun with you guys seeing who would get it right.

I cheated and downloaded to see which file was largest. The file that started as RAW is over 10 times the size of the one that started as a jpg.

It is amazing the amount of information that is lost using the jpeg image. i had not even looked at file size until you posted this. Raw image converted to jpeg is 13 mb to 1.46 on the jpeg out of camera jpeg. Something else i noticed is if it is saved in psd format the mb go to 38.8 in size.

What is the extra information coming from? the actual raw image is 17.2 mb

Normanhall,

Read this wikipedia page for a clear and concise understanding of what a raw file contains and how they relate to other files.

If you think about it, there really isn't any such thing as a raw image or a jpg image. I know that sounds crazy at first, but what you really have posted are two images, one derived from a raw file and another derived from a jpg file.

Even though you may not have actively worked over the files to produce your images, a great deal of default processing and value-setting has gone on in order to get your pictures on the screen. You can take a hand in all that, or you can leave it to the camera and your computer to decide what your picture looks like. Can we presume you left it to the camera and computer in this case?

All digital photo files are just the basic clay from which a great variety of images can emerge. As a generality you can do a lot more with raw files than you can with jpgs, but in either case it requires a lot of study and learning about how the whole thing works.

Wish you well if you decide to start that long journey. It is and continues to be a wonderful trip for a lot of us.

All the best, however you choose to do it in the future.

I always shoot raw but i had never compared the jpeg as it comes from the camera verses a raw image as it comes from the camera. yes in camera jpeg then took the raw image and converted to jpeg so i could put it on here. So yes i suppose i have let the computer create the image but other than converting to jpeg i did no pp. If i set the raw version beside the jpeg that was convert from the raw my eye can see no difference, however i am sure there is because of the file size, but to my minds eye it looks the same.

Sure they look the same; why wouldn't they? But the fact that they look the same means absolutely nothing when you're considering the differences between raw and jpg files.

Raw = more info. No 2 has more info. Ergo, No 2 is raw.

Actually I think this was a silly test and shows a lack of understanding on what is going on between raw and jpeg images.
I suspect that with a properly exposed image it would actually be very difficult to see a difference. :roll:
