TIMELAPSE PROJECT
Over a year a new photo has been uploaded every 15 minutes from my webcam (thousands of photos)
I am looking for a simple way to
1. Pick one picture from each day, taken as close as possible to 12:00 midday
2. Then move all selected files to a subfolder
The filename format is YYYYMMDDHHMMSS (ex.20180715035717.jpg)
Date modified is also available in file details.
PS: Date modified/ LastWriteTime is -2 hours from when photo was taken
Any help would be appreciated
Screenshot of folder with files
Example: For each photo taken between 11:50 and 12:10 move to subfolder

If you want to use the timestamps in the file names, the below code should do what you want:
$sourceFolder = 'D:\test'
$destination = 'D:\PicturesAroundNoon'
# if the destination path does not exist, ceate it
if (!(Test-Path -Path $destination -PathType Container)) {
$null = New-Item -Path $destination -ItemType Directory
}
# get a list of FileInfo objects for the files to move
Get-ChildItem -Path $sourceFolder -Filter '*.jpg' -File |
Where-Object { $_.BaseName -match '^\d{14}$' -and $_.Name.Substring(8,2) -match '11|12' } |
Group-Object @{Expression = {$_.BaseName.Substring(0,8)}} |
ForEach-Object {
if ($_.Group.Count -eq 1) { $fileToMove = $_.Group[0] } # return the only file for thatdate
else {
if ($_.Group.Count -eq 2) {
$index = 0
}
else {
$index = [math]::Floor($_.Group.Count / 2)
}
# get the middle two files from the collection and test which is closest to 12:00
$file1, $file2 = ($_.Group | Sort-Object)[$index..($index + 1)]
# get the dates from the file BaseName property
$date1 = [datetime]::ParseExact($file1.BaseName, 'yyyyMMddHHmmss', $null)
$date2 = [datetime]::ParseExact($file2.BaseName, 'yyyyMMddHHmmss', $null)
$noon = Get-Date -Year $date1.Year -Month $date1.Month -Day $date1.Day -Hour 12 -Minute 0 -Second 0
# get the time distance to 12:00 in seconds
$dif1 = [math]::Abs(($date1 - $noon).TotalSeconds)
$dif2 = [math]::Abs(($date2 - $noon).TotalSeconds)
$fileToMove = if ($dif1 -lt $dif2) { $file1 } else { $file2 }
}
# now move the file to its destination
$fileToMove | Move-Item -Destination $destination -WhatIf
}
Remove the -WhatIf if you are satisfied with the results shown in the console
