Exporting Presets

"created a preset and tried to export it"

In the 'old' Lr5 - Develop Presets are saved in a folder as .LRTEMPLATE type files.

In your system they will most likely be in a folder like this-

C:\Users\{Your Name}\AppData\Roaming\Adobe\Lightroom\Develop Presets

You do not need to "Export Presets"- you only need to Copy&Paste them from the folder location.

As for Image Exports-  When you open the Export dialog, you select the file-type [Image Format] you want, eg. JPG. (Note DNG is a raw-type of file only viewable in a raw editor like Lr.)

FYI: You are using the (very) old Lightroom 5, a predecessor of Lightroom Classic, before Lightroom (cloud) was even born.

I move this to the correct forum - It was moved before by mistake.

Anyhow, it's still (at least to me) not clear what you are trying to do.

What type is the source photo - jpg or raw?

Are you trying to export to jpg or to DNG?

Are you trying to reset the developments to the state the photo was at import?

FYI: https://en.wikipedia.org/wiki/Adobe_Lightroom

Please confirm the version you are using: Lightroom or Lightroom Classic? Also, let us know the exact version number as well as your OS.

Do you want to reset the developments made or the export settings?

Please be more detailed in where you come from and what you are trying to achieve.

Okay, to explain more, for those of you who have Lightroom will understand what I mean when I say export. You go to library and in the left corner on the bottom are the import/export options. Well I watched a tutorial and in it they said to select the export button. Under that there are two preset wedges in the upper left corner. I selected one and selected that they be exported as DNGs or whatever those are, and now I can't get my normal settings back! Now it only exports the preset, not the picture no matter what picture it is. I'm not techy to this is super confusing 😭
