File/Image Sizes when uploading from iPhone SE

[martinv44029552]

Firstly, I'm a technophobe, so except I may be going about things incorrectly.

I started uploading my images from my iPhone SE to Lightroom, when Adobe Bridge stopped recognising my iPhone. I have the latest versions in both Apps.

My question is about file/image sizes which appear to be different depending on which App I view them in, be it Adobe Bridge, Lightroom or in the Photos App on my iMac.

Does anyone have an idea why this is?

Do images compress slightly when transfering from one app to another and is there a way of preventing this, other than changing size in Photoshop?

I hope this makes sense, any help would be very much appreciated.

Thanks, Martin

What do you see, please describe in detail, that makes you ask this: "My question is about file/image sizes which appear to be different depending on which App I view them in, be it Adobe Bridge, Lightroom or in the Photos App on my iMac"

Transferring a file from one device to another should not change the file size and should not change the image size.

"in the Photos App"- Well that could be a problem to begin with. The Photos App 'hides' your full-size files in a file Package, and other Apps (Lightroom, Bridge, etc) may only ever have access to a small JPG preview file of the images. This may account for file-size difference.

Three Screen Shots.

Mac Photos Unmodified and Lightroom the size is the same but in Adobe Bridge/Photoshop the size is different?

I am not a Mac person, but I suggest you are not 'looking' at the same file.

The file viewed in Bridge has a long dimension of 2048 pixels- which again suggests to me that it is a Preview file or a file downloaded from the Cloud that is not the original.

I don't think I can be of any more help.

Perhaps other Mac users have some answers.

You are using Lightroom - all your photos are in the Cloud. Your sample in Lr is a HEIC file.

Adobe Bridge - Can only look at files on your local hard-drive, and my Bridge will not display HEIC files. This is what I see in Bridge (for a local file on a hard-drive) and when I try to open it in Photoshop-

Ok, thanks Rob for trying.
