Help? Image quality settings error

I have been working with Fireworks for a few years now. Just
recently I started having or noticing this problem:
If I try to save an existing jpg (or a png file, or other) to
a jpg format using Save As, and then click on the options dialog
box to open the Image Preview dialog box, and adjust the quality
slider, and then save the file - the newly created file is not
affected by what I set. To make it a gross example, I took an image
with good clarity, and adjusted the quality to 20% so that it
looked all pixelated in the priview box, but when I saved it, it
came out clean.
Any comments, explanations, help?
thanks,
David

Increasing the quality after the file has been compressed is
not going
to give you a better quality image. At some point the file
was saved
with a quality setting of 37%. So even when you set the file
to 100%,
you're only getting 100 % quality of a highly compressed
image. You
can't undo that unless you have another version of the file,
perhaps the
original.
Keep in mind that jpeg is lossy; it permanently discards
original data.

Export panel bridge cs5 - image quality only to 10

Hi
Is anyone else having problems with the image quality settings in the image options. It cannot seem to save the max setting of 12 it only save jpegs at 10.
Any suggestions, Thanks Andy

I had the exact same issue - except mine is limiting it to a maximum of 8
The workaround I found is to build the export profile exactly as you would like it - and let it pick whatever number it wants (8 or 10) - ignore the words of Low/High/Maximum - those just correlate to the 8 or 10 (or 12)
12 is the true maximum for the JPG export and once you run it - there is a noticeable file size increase and the images are a higher quality.
Once you have the profile built, go into the folder "Export Presets"
Macintosh HD > Users > YourUsername > Library > Application Support > Adobe > Bridge CS5 > Export Presets
Open up the file that matches the same name as what you created inside bridge
The file will likely open as an .xml file inside dreamweaver (or another XML editor)
find the line:
<imageQuality>8</imageQuality>
and set what the system set as an 8 (or a 10) to a 12
<imageQuality>12</imageQuality>
save the file and run the export again.
You will have what were 2-4MB JPG files becoming 8-12MB files with a quality of 12/Maximum
Hope that helps

Best image EXPORT settings for best quality

What should i have my export settings at when exporting to a jump drive to give to clients for web and printing use???
When i see my images uploaded on Facebook for example, the qulity looks poor which worries me that when printing the quality will be poor as well. Am i missing something in the setting for exporting? What is the proper way to export for the best quality image? HELP!
My settings now under Aperture>Presets>Image Export:
JPG Original size
300 dpi

Are there specific settings with-in Aperture I can set for exporting so that clients have the ability to print as wanted and post on the web as wanted whithout losing any major amount of photo quality?
No, not for one size fits all.
I do appreciate this may be a frustrating answer, but non-the-less, that's how it is.

Should I be gving 2 folders of pictures, one for web use and one for printing use? If I were to do that, what should the exporting setting be set for both folders?
Maybe, it's your choice.
Let's go through the settings.
The only real quality setting is for JPG compression. 12 is virtually no (lossless) compression but gives huge file sizes which may breach a websites limits.
A 16MP images on quality 12 will be about 22MB. 11 brings it down to 8MB and 10 down to 7MB. You'd be very hard pressed to see the difference between a 12 and a 10. But if you want to feel you are giving the best quality without the extreme file size, go for 11.
The the vast majority of web sites, like facebook, will either resize uploaded images and/or re-compress them. They may also crop them to a different aspect ratio to fit their browser software.
Many report the best size for upload to facebook, for small images is 960 pixels on the long side. For large images it's 2048. For different websites it may be different. It is discussed on many photography sites and blogs. You will find some promoting the 960 / 2048, and others with their own preferences. Here's a good one which also shows you many ways FB will mess with the images:
http://havecamerawilltravel.com/photographer/images-photos-facebook-sizes-dimens ions-types
The safest colour space is sRGB (Mac profile: sRGB IEC61966-2.1) as it will more often be right than wrong. You should preview your images on screen with this profile to get a feel for how it will look and avoid unexpected colour shifts in your files. Ideally your screen should be calibrated so you know what you are giving them is accurate.
To understand the printing issue, try this exercise:
If you have a printer installed on your Mac, it probably also installed some printer profiles. In Aperture, look at one of your nicer vibrant images. From the view menu turn on 'Onscreen Proofing' and then from the 'Proofing Profile' sub menu, select one of your printer profiles and look at how the onscreen image changes. Repeat with each of the printing profiles and see how the image changes each time.
This is only a fraction of the colour shifts that will be occuring after you give your file to someone and they print it on their own uncalibrated system with their uncalibrated printer.
Many photographers don't offer full size images to their clients. They will usually give them smaller versions for their own use, which may include small size printing.
They will either do the main printing themself on their own calibrated printer, or work with a print shop, and may have installed calibrated profiles on their system for the shops printing equipment so they can use onscreen proofing to gauge what the pictures will look like when printed on that equipment.
But if you are just giving a file to someone, you lose all control of how they will print it. Even experienced photographers and computer users can struggle to make the prints match close to what they look like on screen.
Most often photos will appear too dark, or the colours look wrong, or it lacks sharpness. There are some settings on the export presets for gamma and blackpoint compensation. Gamma will brighten the image for when it's printing too dark, and blackpoint will try to stop the shadows turning black (within the chosen colour space). But as you don't know in advance whether the images are going to print too dark, or the shadows are turning black, you can't really set these for a one-size fits all scenario.
So there are not many settings to help you here.
You are actually moving into the realm of defining your product. You could, for example, ask the client which site they intend to publish the photos on, research that site and produce files optimized specifically for that site.
You also need to decide what size (resolution) files to give them for printing and whether you are happy giving away your full size images.
These choices will lead you to a number of a different files sizes as 'your product', all should be in sRGB colour space, and all with quality 10 or 11. For any client's who know how to make use of a wider clour space like Adobe RGB for printing, they will probably ask you up front to supply the print versions as such.
Next, for each size and usage, you now need to sharpen these images.
This is because sharpeing is best applied to images that have been resized to their intended output size and should be sharpened in accordance with how they will be viewed. Images displayed on computer screen generally need less sharpening than those that will be printed. Depening on the printer, the images may need some oversharpening in the file, in order to appear crisp and sharp in the print. As you won't be controlling the printing process you should probably avoid oversharpening. The bottom line is, if people are taking on the task of their own printing, they'll need to figure out what they are doing to get good results, or use a commercial printer.

I just set up a new computer running Windows 8.1. When I go to my icloud photostream, the pictures are in PNG format NOT JPG. When I open and upload photos from the photostream, the resolution is so low that the image quality is terrible. Help?!?

Hey Sierra, You can do just what you have stated. My question, what is your "other"? If it is over 1.5 GB you most likely have corrupt files. Doing a Restore to New, Factory restore should correct it. Just make sure you make a full backup of all information on your iPod to your computer before you restore, so you don't lose your stuff, contacts, videos, pictures, non-iTunes music, etc, use the cable and connect with your computer. Then, via cable, connect to your computer, run the Restore to new, don't use your backup. Treat this iPod as if it was your first one ever. When restore is done, set up and add what info you wish to install on this iPod. The music apps etc you purchased should be on your computer, if not you should be able to retrieve purchased apps and music from iTunes. Any music, videos, apps not purchased from iTunes will be lost to you if you do not save them to your computer or the cloud first. When your done, make a current Backup and you should good to go. Hope this helps. Good luck. Cheers.

HT201335 Airplay Mirror Poor Image Quality on CBS app - help?

Airplay mirror from iMac/iPad to HD TV w/Apple TV has a Poor Image Quality when watching network shows via for example the CBS.com site or the CBS app. The image looks dark, not HD at all. My internet speed/performance is obviously not the issue because Hulu, Netflix etc all come in great using Apple TV ~ sorry, not all that savvy in this department, is the poor picture down to it just being a mirror of the iMac or iPad or is there a setting or something I am missing?

You should use the Acrobat extra menu in word 2010: then edit Preferences and choose Conversion settings : High quality print
Hope it helps

Question about image quality! *please help*

Hello everyone!
I'm actually a beginner at FCP, so sorry if this question sounds kinda dumb:
I just shot a video in a DVX100, and imported it onto FCP. When I play the video
on the viewer, the quality of the image looks just fine. When I put it on the timeline
for editing however, the image quality drops quite a bit. How can I match viewer settings
with sequence settings?
Thanks a lot!
Stef

Step 1 would be to ensure the sequence settings match the source video settings. If the sequence is set to a lower quality size/codec than the original video, it will be reduced in quality in the timeline.
What sequence settings are you using?

Need help with full screen slideshow image quality

I am looking to display some images with full screen slideshow. The images I add are very large, over 5000 wide. When I publish the site some images retain their quality while others lose it and look like crap. Why would this be and how can I fix it. I tried to resize them to the 2560x1707 that muse does, and then add them. This doesn't change the end result of poor quality.

Go to Assets Panel and locate the image you want to use at original size. Right click the image and chose 'Import Larger Size'.
See if that helps retain quality for that image, since Muse does not resize/interpolate that image for you.
Cheers,
Vikas

Please help! Elements 11 image quality poor compared to LR

Hello, I just started using elements and am very irritated because the image quality is very poor compared to when i am viewing in LR. Its not the conversion - i have tried pulling directly from the camear. It looks great in Camera Raw 7.1 but the second i pull it into editor, it lines get jagged. Adobe help is telling me this is normal. Surely not?? Something about a halo around pixels? Image on left is Elements 11, right is Lightroom and Zoomed in so you can see how sharp it is. PLEASE help. im so frustrated!

In the pse 11 editor are you looking at the image at 100% view (actual pixels)?
(Other viewing percents can be misleading in the pse 11 editor)
Double click on the zoom tool in the tol box to get 100% view.
Also you should be on camera raw 7.4 available from Help>Updates within the pse 11 editor.
Is that lightroom 4.4?

Still image quality poor, Help

I posted a similar question last night. This one is more of the same.
Issue: Poor image quality (flickering, Jumping) when viewing stills on my TV only...
I have made 2 test videos. One was made in FCE and one in iMovie8. Both are identical and consist of only 5 still pictures. I added motion to a couple of pics in each test. The video from iMovie looks great on my TV. The video fro FCE looks very poor. The image is jumpy and flickering.
Why does the same movie movie look different depending on the source? What is different? Do I have something set up incorrectly in FCE?
I tried applying the De-interlacing filter and the Flicker filter. I tried all variants of the De-interlace filter, ie odd/even. I have made several exports from FCE trying to get rid of the flicker/jumpy-ness to no avail.....Even the still pics that have no movement flicker a bit from FCE, for example, one of the pictures are of my son holding a dark green fishing rod while standing in a tent. The picture has no movement but the fishing rod and tent poles are flickering, almost like there are lights in them blinking on and off. A similar picture that has movement shows the fishing rod as alternating dark and light lines instead of just a dark green rod. The same pics from the iMovie clip look great. The color is correct and no flickering at all.
To export from FCE I am using Quick Time Movie. From iMovie 8, I am using 'Export Movie' high quality. On each video I then just dropped them into iDVD and viewed on my TV.
I am a new user to FCE and so far I like it much better than iMovie 6 or 8. I have a hard time believing that the still picture quality output form FCE is worse than iMovie. So I must be doing something wrong.
Thank you in advanced for help,
Toshiro

Well I can only assume that there is a difference in the way the data is handled between the 2 apps. I have resolved my issue by not compressing the data while exporting. Unfortunately, my 3 minute video is 7G !!...oh well
...now if I could just get rid of the thin green line at the bottom of the screen during my opening segment it would be great....
Thanks for taking the time to assist

PLEASE HELP! 67MG PDF file can't reduce to email without losing image quality

I have created an 88 page fashion look book for work and it needs to be emailed out pronto to our customers!
I created it using In Design (the latest version)
I saved it as a PDF for my records - Highest Quality for printing purposes.
I open it in the latest version of Adobe Acrobat Pro XI - Version 11
When I compress the file it goes form 67Mg down to 10MG which is great, however the image quality is not good enough.
Being a fashion brand we need it to look crystal clear!
Can anyone help me and tell me where I am going wrong???
Thanks you in advance, Nicky

Try working on the images themselves before you create the original document. I don't normally recommend JPeg, but if you have pictures the feature of JPegs that reduces the color sharpness may help. Once you have what you want, you might then change it to a TIFF or PNG file. You can also do an audit in the PDF (save as>PDF Optimize) to see where the bloat is located. It is likely in the images. In that case you need to see how to reduce the size of the original images (actually work on copies so your originals stay good). It may be that you are using too many pixels (300-600 should be good in most cases) or you might be able to reduce the color depth (256 colors might be adequate. When you use the photo in ID, be sure you use it at 100%. If you need to change the size, do it in a graphics package that can properly interpolate the bits. You should do physical size reduction before you reduce the resolution. It may be that what is happening when you do the compression to 10MB is that the interpolation of the pixels is getting in the way. So doing all of this on the graphic before you use it would help a lot. I may not be a graphic expert, but trying to work on the original graphic to size and quality before you use it is typically a first step to a good look. PhotoShop should be able to do the reduction, but a simple program for such is IrfanView.

Help... Best image quality from FCP to DVDSP... (FCP project at 1440 x 960

Hi all,
Yes, I just finished an edit in FCP with frame dimensions of 1440 x 960 (Not HD). (Don't ask . I am on the hunt for input for the best way to get the highest quality when I take the 1440 x 960 video down to Standard definition DVDSP. For example, should I just drag-n-drop a reference movie into DVDSP and let DVDSP do the resizing?.... or maybe I should use Compressor to resize first? etc.. etc.. etc... (If I should use Compressor to do the resizing... a little help on what settings to use would be great)
This is a graphically heavy video with a lot of client logos, animations, etc.
Thanks a bunch,
Matt

What format are the assets? As PDTV said, don't even think about recompressing an MPEG2 file if you wish to retain quality.
There are tools such as DVD2One which you could look at, but if this is 8GB of MPEG2 then use a DL disc.

Losing Image quality when saving to JPeg and posting on line! Please Help.

Hi,
I recently got a new computer. I use CS3 to edit. For some reason, whenever I resize the image, save it as a Jpeg and post it to the web, it loses image quality. Severely. I've never had this problem before....until this new computer.
I usually resize the image to 800, then simply click on Save as Jpeg. Once I resize, it looks fine CS3, but NOT online.
Just a picture of my kid. No critiques please! : )

For blog software, you will have to look under Manage under your admin account. There's an option to define the maximum image size for previews (inline images) and medium image sizes. if they are set to samll, the software will resize them, yet the theme you use may scale them up again to full column width, so they look mooshy. Make sure the image size in the settings panel matches the images you upload. For Facebook it may be similar, but I won't rule out that eitehr of the two services frcibly will change your images to save bandwidth. This should be stated in their terms of use somewhere. If you're merely referring to color shifts, you may wish to check your default color settings and the Embed color profile and Preserve RGB options in the Save for web and Devices dialog.

Firefox mage quality and resolution was superb when I used XP and Vista. Now that I have Windows 7, however (with the Firefox 3.6.3 version), the image quality and resolution is poor. Please help me!

I am using the Firefox 3.6.3 version with my new Windows 7 operating system. When I used all the previous Firefox versions in my XP and Vista operating systems, image quality and resolution was excellent! However, now that I have upgraded to Windows 7 and Firefox 3.6.3, the image quality and resolution is poor (unacceptable for downloading purposes).
== This happened ==
Every time Firefox opened
== I first activated my new computer and installed the Firefox 3.6.3.

All my images are pixelated in firefox 3.6.3
http://www.dcgdcreative.com
Not only on my site but on most sites I view.
The issue is not solved by resetting the zoom text view (ctrl+0)
The issue is not resolved by starting in safemode with add-ons disabled
The problem seems to only affect .jpeg files and only on Windows 7 on my desktop; as I have viewed several sites using windows XP with my laptop, no issues.
I had the same issue with IE8 and was able to fix the problem with by setting up the compatibility view for all sites. Issue fixed no problems at all. But nothing similar for firefox?
Whats the deal?

Creating PDF from File is creating poor image quality.

When I combine files to one PDF I am receiving terrible image quality. I'm importing PNG's and I set my preferences to maximum PNG quality.

when you say "it keeps failing" what does this mean? Do you get any error message or messages?
The best way to create any pdf file from Microsoft Office package is to print to the pdf file as you have already tried. If this fails for any reasons you can save the file in PPT or any Office packages as PDF as long as you have the latest versions of Office - 2007, 2010, or 2013. For Office 2007 you had to download an Add-in from Microsoft website to "Save as" pdf but 2010 and 2013 are automatic.
Hope this helps.
