I shoot with a Nikon D 7200 and prior to processing my pictures my Mg. normally read 28.9 or thereabouts. This morning when shooting in normal conditions the Mg.read between 17.9-19.2. Does anyone have an reason for this?
Thank you in advance for your reply.
Thank you in advance for your reply.
Are your current photos a lot darker than usual? Someone said file size changes as darker photos have less information than lighter photos.

The images are the same; they are not darker. I totally blew the the term for my post. I'm sure it should have said megapixels and I apologize to everyone.

Is the issue resolved or not? Changing the subject to 'pixels' only makes whatever this issue more confusing. Your camera is a 24MP sensor. It will never record more than 24MP given a sensor sized 6000 x 4000 pixels. Page 81 of your manual discusses the settings to change the image size of your camera.

I agree with Paul that you may have changed an image quality setting. Here’s a screenshot that should help.

If you said megapixels it's not possible. Your camera can not produce either 28 or a varying between 17 to 19 megapixels. It's the megabytes in file size and the varying file size related to compression. You must have changed either from 14 bit lossless compressed to either 12 bit lossless compressed or compressed.

The D7200 will shoot raw lossless compressed. If that is your mode, the compression could easily cause variability in the file size. An image with large expanses of space without a lot of detail will compress more than areas with lots of detail.

I'm guessing you mean mb for megabytes. It depends on a few things. If your shooting in Raw , jpeg. jpeg normal , fine , etc. But most likely it is the amount of detail in the photo. A photo with mostly a empty blue sky will have less info than a smaller sky with clouds , & more landscape with trees & mountains.

What tcthome said. I shoot in RAW with a Canon EOS5DS-R. The file size will vary from around 50mb to around 80mb depending on the detail in the photos. I am looking at two photos of birds in flight - one taken looking up at the sky so there are just the birds and sky (58mb) and one taken lower so there is a tree and some bushes at the bottom half of the picture (73mb). No settings were changed between the shots. This is completely normal.

Mg is the correct spelling for Mega Gram (capital M lower case g and not mg which is miligram) which is 2204.62262 lbs.
Bob to the rescue !
Obviously, the camera is lightest in the morning. Then, as the day progresses and the moon aligns with the sun, more gravitons pour in along with the photons collected by every exposure.

What is the content of your image? The number of pixels is determined by your camera, and is always the same. The number of bytes is determined by how much detail there is in the image. An image without a lot of detail uses less space on a computer. At least that has been my experience.

The computer generally lists the file size in MB (megabyte) rather than Mb (megabit) which is generally used for data transmission speed.
👍👍 Thank you for mentioning that - a mistake made regularly. Not to be nit picky, but since it amounts to an 8x difference, it IS important to get it correct if you want to provide and receive accurate information.
