Fuzzy/Pixelated Images on Facebook

Chimera H , Apr 09, 2010; 01:49 a.m.

I'm having problems posting pictures on FB. The images are very fuzzy (maybe even pixelated) looking. Sometimes the pictures aren't so bad , while other days they are so fuzzy and I can't even post them. They look fine in PS, but I do notice a slight fuzziness on Blogger too. I don't know this with most other photographers, so there is something I'm doing wrong.

I shoot at full resolution and am wondering if there is something I need to do in PS when I save the images. I set the resolution to 72 and sharpen and usually take the size down to 600 or 800xwhatever.

Does this have to do with color setting, etc? The following are mine:

Mode is RGB color. Proof Setup is Monitor RGB.
Workspace:sRGB, CYMK-US Webcoated (Swop) V2, Preserve Embedded profiles
Assign Profile: Don't Color Manage this Document
Someone once said I should "Convert to Profile" to sRGB before saving?

So frustrated. Thanks

Generally sharpening is the last thing I do to an image, after resizing even. Furthermore it seems you are resizing it twice; once when you set it to 72 ppi, and another later on when you set the dimensions. Try doing this only once and at the same time, then sharpen, and see if the images improve.

Thanks Jake! Yes, I was just playing with the image and it seems when I took the large 16x20 image and set it at 72 ppi, the image was more clear on FB (not perfect, but better). If I brought the image down to 5x7, then set it to 72ppi, it was fuzzy.

Thanks again! I'll see what I can do.

Darn. Nope, still too fuzzy. Do I open "Image" then simply change the resolution to 72 or do I change the resolution and pixel dimensions? Or are you saying crop the image and change the res. right when I crop it?

I've been experimenting with uploads to Facebook. It appears Facebook automatically does some resizing and compression, so it may not be possible to use it for best possible display of critically sharp photos, no matter what we do.

Pay no attention to the 72 dpi, etc., stuff. It doesn't matter for uploading photos online, whether on Facebook or photo.net. That's a printing instruction and has no bearing on monitor resolution.

I'm just resizing photos to 700 pixels wide or smaller, adding a little sharpening after resizing, and not worrying too much about how they appear on Facebook since it's impossible to completely control the final appearance. I just regard 'em as snapshots, nothing more.

Yes, Lex, but other people have pretty clear images, so I want to know how they do it.

Lex Jenkins , Apr 09, 2010; 02:29 a.m.

Be sure to work from a copy, of course, to preserve your originals.

Use the "resample" option in your software, not "resize" - depending on your software the resize option may produce artifacts, jaggies and ugly results. Resample to around 700 pixels wide. Use a little sharpening after down-sizing. Sometimes a simple bit of light global sharpening is good enough, sometimes you may need to set a custom unsharp masking setting for the small JPEG.

Again, ignore the 72 dpi, 100 dpi, 300 dpi stuff. It doesn't matter for shrinking JPEGs to be suitable for web display. Only the pixel dimensions matter.

I agree, nevermind the 72DPI stuff. I resize my 10 and 12MP camera images to 750 pixels in Paint Shop Pro XI, do an unsharp mask and upload them. I've got hundreds of images in various albums and groups I own/belong to, and they are decently sharp. Especially since Facebook recently upsized the way the images display.

Chimera - Are you able to consistently post images to photo.net which meet your standards of sharpness? I quickly looked, and couldn't find any images that you posted, but I did notice that you have mentioned image sharpness problems in a number of threads. I'm trying to discern whether your problem is only with Facebook, with the method you use to prepare images for the web (ie, in general), or with your initial capture. Examples would be *extremely* useful.

BTW, photos on Facebook will get a bit better. They are increasing the size to 720 pixels:
