Nice photo and good work on the edit to make the water pop. Cellphone cameras are pretty good, but I still prefer a dedicated camera for most situations.
Most instances will prevent you from uploading "large" files. For lemmy.world, I think the cap is around 2 MB. It's actually somewhat frustrating because my (most/all?) client apps allows you to upload photos, but the upload will fail 90% of the time. There doesn't appear to be an API to check for this size limit and/or the client(s) aren't using it and resizing a temp copy of the photo before upload. I often wonder if this is contributing to a somewhat low post level... I make the vast majority of my posts from my PC for this reason if they're going to have more than one photo.
I usually take pictures on my phone as it's always with me, but for this specific situation, the telephoto lenses restrict too much light, and so the image becomes too noisy and artifactey as the phone tries to compensate for it being under-exposed.
As for the upload limits, i was able to upload the photo at a much larger size (~8mb), but it failed to show a preview of the image, so i had to scale it down even more.
