Did compression ratio change?

nixage

I'm suddenly seeing lots of artifacts in some of my images that didn't have them before and do not show up in the full resolution versions. I know for speed/bandwidth purposes the images displayed in galleries are compressed but has this ratio changed recently? Some of my pics are looking like crap because I shoot concerts a lot and there's a lot of areas with no detail.

here's an example

thanks!!!

Update: Came across other folk's images that have the same (compression) issue: http://dgrin.smugmug.com/gallery/4188691#252581908_qZAUg

Nope, we didn't change. What browser, computer, OS, and ISP are you using?

Using osX with Chrome and Firefox (both show the artifacts). Out of curiosity, I checked the same images on my flickr account and they don't show the artifacts. Seems like compression is very high on these.

Update: Safari is showing less of the artifacts. Not sure what's going on but will have to do some more digging.

Ehhh. Can't figure it out. If you guys didn't change anything, not sure what's going on then. Thanks for the speedy response though.

Make sure all your browsers are set to 100% view with no zoom or scaling set. When the browser scales an image, it often leaves artifacts because they try to do it a quick way, not the best way.

Thanks jfriend.

I checked on google chrome but they have no such setting. I've seen differences in color before on different browser platforms, but was unaware of quality and compression issues. Doesn't surprise me though.

I wonder if having an option (in Smugmug) to change quality levels in the galleris would make any difference? Of course higher quality would mean slower load times, but it would be nice to have the option.

thanks again!

But you can set zoom levels on Chrome using ctrl+ and ctrl-.

Our Display copies are HUGE and over the years we have upped them in quality. I can't think of a single complaint in the past couple (more?) years that we've gotten, about JPG quality. We very carefully monitor this!

Of course. That's not the issue though

Understood! I'm not complaining, just trying to figure out the source of the problem. Looks more and more like it must be the browsers. I'll check explorer as well next time I have my VM up.
