Jpeg artifacts on Photographica...help!

By throughtheeyesoflauramars written 4/11/06 8:42 AM, published 4/11/06 8:42 AM
Ok...so I take a shot and it looks great after I photoshop it. I have CS2 and I always start by making it a SmartObject and then rasterizing it. I manipulated the photo and all looks good. I save as jpeg at 72dpi and at high quality (10). The image still looks good. Then I upload it to photographica and it turns to crap. What happened and how do I fix it. I am afraid that someone will purchase an image from me and it will look great on my computer, but look like dog poo to the client and I will never be hired again.....help!

    I've been mulling over your question and...I don't know. I've never used the SmartObject thingy or rasterized an image. I wish I could help ya...

    1. After you save the image as JPEG/High and "The image still looks good" what software are you using? PS? or IE/Netscape? (granted, it shouldn't make a difference, but....) 2. Something I do to check the print quality of an image is a) shrink it to 4x6x300 or b) cut out a 4x6x300 piece and send it to Walmart for a 4x6 print. At $0.20 a print, I can see in 60 minutes whether or not my monitor is jacked, or what. (and I have a walmart about 2 miles from the house! I can get my exercise at the same time!) Other than these stabs in the dark, I'm with ASpace... dunno... I'm gonna check out my images again, though...

    - Huh?

    Another question... What is the image size and filesize of the JPEG you uploaded? ... let's use "Crap Example #1"

    - Huh?

    2700x3000 11mb

    ^^^ That's the size you uploaded here? Cory says that the image resizing process here doesn't touch the image itself and just strips extraneous information, but I would try to resize it down in photoshop before uploading and compare the two side by side. Crop Example 1 is currently showing a size of 539x600 and a file size of ~57KB. First thing I would try is like I said above...resize in PS on your side, "save as" highest quality JPEG and upload it here and compare them side by side...

    Another thing I do is "Save for the Web"... that's avail in PS 6, I don't know about cs2.... but that will allow you to change the "quality" of the file and see the resultant filesize. I cut mine to whatever percent is closest to 200 kb. (and honestly, of my Netscape, I don't see a difference between 100% quality and 45-50%). Now, if I'm printing, that's an entirely different story, but I'll write a book on that later.

    - Huh?


  • codepoit 4/12/06 8:19 AM
    Yeah, I use save for web as well (in CS, so it's gotta be available in CS2 as well) for images that I post here. But apparently the resizing deal here at PH uses a very similar algorithm as PS's save for web. So that's why I would say to try just a save as for now for comparison...

    it is in CS2. I avoid it because early on, it was causing crashes on the site when I used Save for Web. I have big RAW files--I resize to 800x533 and save at highest JPG setting of 12. Then I upload.

    In CS2 there's a feature that I think is outstanding for resizing and getting images ready for posting on the Web. It allows batch processing of files to resize and convert color profiles. Go to Tools...Photoshop...Image Processor. It allows you to resize images, convert to jpeg and convert color profiles to srgb all at one time. We used this at the Santa Fe Workshop and I became sold on it. BTW, one of the problems I was having before with my image uploads was that I was working in Adobe rgb in Photoshop but was not converting to srgb for the images I uploaded to Photographica.

    - One size does not fit all

    ok make sure srgb is working in all places, tom I may need to pick your brain later on the batch processing, I am hitting a snag. And Chris I will try the side by side comparison soon. Thanks so much for the info please post more as you think of it...or pm me. Back to ps I go.

    Another neat thing the Image Processor script does is size to fit, say you want to convert a folder of images to jpeg and size them to fit, just enter your max horizontal and vertical dimensions and it will fit the image into them and keep the original proportions. On CS2 it is under File>Scripts>Image Processor. I think Tom gave the location in Adobe Bridge which is a great program that comes with CS2. I sometimes can do everything I want to do without opening CS2 itself.

    "Sometimes I can do everything I want to do without opening CS2 itself." Are we still talking about pictures here?

    - Huh?

    Amazingly, Icemarine, I did have my mind out of the gutter this time.
