timpdx Offline Upload & Sell: Off
|
So Google images has been released, its a competitor to Flickr and iPhoto, offering unlimited** (more on that) storage for your images in an interface designed to work well on mobile as well as uploading your desktop images to the service.
**it promises unlimited jpeg upload on images at 16 megapixels or less. It will compress 16mp images slightly.
So I did a quick unscientific comparison of images uploaded to the service compared with the native files on the computer.
First was a Sigma DP2M image, full of detail as these cameras are well known for. But the files generated after processing in Sigma's DPP software come out under 16 megapixels. I processed this image as a TIFF and exported to Photoshop before saving as a 12 quality jpeg.
The results here are excellent, this is a 100% crop of the Sigma image, original jpeg before uploading and then the google result, downloaded back to the desktop and opened in photoshop at 100%.
I mostly shoot Fuji which clocks in right near the 16mp limit, so I pulled from my Sony RX100 which clocks in at 20mp to see what google does as far as compression:
First, google resizes the Sony 5472 pixel wide image down to 4898 pixels wide.
Then, while really not bad at all, I do see jpeg compression (slightly) in the building in the foreground (arrows). The compression seems pretty light and I don't see an excessive amount of it.
I am still playing with the service, in terms of usability, syncing to the iphone, ect to see if it works for me. I am happy with what I see, so far, at least.
(BTW, I thought I could upload full rez images here, they seem small to me. Origs are over 2K pixels wide)
