Quality of jpeg conversion in elements?
HI, i read that converting to jpeg using photoshop cs2 is the best option, and that elements doesn't do jpeg "justice." is this also true with elements 5?
But where did you hear it? If we knew that, maybe that would shed some light on the reliability of the source or clarify what they might have been talking about. Clearly it's not an issue for those who have responded, and I've never heard that CS2 does a better job at converting JPEGs. However, full PS CS2 does have something called "advanced noise reduction", which is said to reduce noise and remove JPEG artifacts. Is this what "somebody" might have been talking about?
I don't use PSE 4.0, so I don't know if that feature was brought into Elements or not; keep in mind PSE 4.0 is based on the CS2 engine, and PSE 5.0 must be, too, since I don't think Adobe has yet released a CS3, have they?

Quality of JPEG when being converted by Folder Actions (Image Events)
I take a lot screenshots with Command + Shift + 3/4. They are in PNG and I love them. Yet, I need to send them via email sometimes.
I convert them to JPEG using Preview, but it is time-consuming when especially I have hundreds of them.
I have just learnt that it is possible to do convert in batch using Folder Actions. However, I meet few very serious problems.
1. In Preview, I could choose the quality of JPEG before converting. But, there is no such option in Folder Actions. I even searched online to try to modify the script and it seems that nobody cares about the quality of converted JPEG.
My question: What is the quality of JPEG converted? And, is it possible to modify it?
2. Since I do not know the quality of conversion using Folder Actions, I tried different qualities using Preview and match the outputs with those using Folder Actions. I got no result. As Preview is using Core Image as the processing architecture.
My question: What is the image processing architecture adopted by Image Events?
3. If the quality is unchangeable, can anyone teach me how to write a new script to do the conversion using Preview?
I really hope Mac OS gurus could explain these to me and possibly solve my problems. I am interested to learn the AppleScript part to modify it.
Thank you very much.It is the original folder action script from Mac OS. Here is the copy.
Could you help me as well where to add the "compression level"? Also, what do "high", "low" and "medium" mean, in % just like Preview, if they use the same image processing architecture?
Again, thank you very much for quick reply.

Image - Duplicate as JPEG
This Folder Action handler is triggered whenever items are added to the attached folder.
The script creates a JPEG version of the file, but leaves a copy of the file
in its original format. If the original file is already in JPEG format, the script does
not duplicate the file.

Why is it so difficult to convert a Raw image to a jpeg in Photoshop Elements ?! I have version 12. Once i realized to change the tick box in Camera Raw to 8 bit instead of 16 bit and Flatten image ( sometimes can flatten image if the flatten option isn't greyed out) hey presto i thought i was up and running. However after saving the photograph as a jpeg and renaming it e, after the word edit. I switched off/on my computer only for all the images i had spent time working on to have disappeared. Feeling very upset as there is no Technical Help to telephone at adobe and i don't know what to do.
My daughter has had her Razr for about 9 months now. About two weeks ago she picked up her phone in the morning on her way to school when she noticed two cracks, both starting at the camera lens. One goes completely to the bottom and the other goes sharply to the side. She has never dropped it and me and my husband went over it with a fine tooth comb. We looked under a magnifying glass and could no find any reason for the glass to crack. Not one ding, scratch or bang. Our daughter really takes good care of her stuff, but we still wanted to make sure before we sent it in for repairs. Well we did and we got a reply from Motorola with a picture of the cracks saying this was customer abuse and that it is not covered under warranty. Even though they did not find any physical damage to back it up. Well I e-mailed them back and told them I did a little research and found pages of people having the same problems. Well I did not hear from them until I received a notice from Fed Ex that they were sending the phone back. NOT FIXED!!! I went to look up why and guess what there is no case open any more for the phone. It has been wiped clean. I put in the RMA # it comes back not found, I put in the ID #, the SN# and all comes back not found. Yet a day earlier all the info was there. I know there is a lot more people like me and all of you, but they just don't want to be bothered so they pay to have it fix, just to have it do it again. Unless they have found the problem and only fixing it on a customer pay only set up. I am furious and will not be recommending this phone to anyone. And to think I was considering this phone for my next up grade! NOT!!!!

Improve quality of JPEG images
Hi
I have an application which saves images in JPEG format after editing (well, many applications does that, but this is only a fraction of what this application does) :-)
I can't use any other formats due to size restrictions. The problem is Image Editing module of this application has operations like line drawing and text inserting. When I save the image, fine lines (especially texts) are getting blurred.
Is there any way I can increase the quality of JPEG files saved? I understand that JPEG is not meant for sharp lines and texts but with Photoshop, even fine lines and texts appear good when saved as a high quality JPEG file. Is there any such method in Java by which I can increase the quality of JPEG images?
Thanks in advance...Is there any way I can increase the quality of JPEG files saved? I understand that JPEG is not meant for sharp lines and texts but with Photoshop, even fine lines and texts appear good when saved as a high quality JPEG file. Is there any such method in Java by which I can increase the quality of JPEG images?I JPEG is a non-conservative compression format (you do not get back exactly what you put in, it has "acceptable degredaton"--I talked with the author before it became popular and he explained what JPEG was all about--high compresses resulting in a small size for internet communications over dialup.
In more recent times I've seen quality factors brought into play with JPEG, but as you have stated, even in Adobe Photoshop under the highest quality, you still have degradation. I've seen some hint and some state that you can get a lossless JPEG, but I've not encountered it yet.
In any case, if you do find a "lossless JPEG" the size of that file is going to be bigger than you are looking at now. You may consider other file formats--TIFF or there are even more recent files formats that have higher conservative compression algorithms. -
Hi All
I teach a photography class at a local college where the students have to submit assignments regularly. Our requirements are that they hand in a print and an unedited RAW file. Because we are focusing on their photographic technique, they aren't allowed to edit the photos at all.
They then print the photos at local photo labs (fuji fronteir machines) but the printing results are inconsistent and sometimes shocking.
to cust down on possible workflow problems, I have advised them to build a relationship with their printer, use calibrated monitors (which we have at the college), etc. etc. However, I am starting to suspect that the problem lies with the RAW to JPEG conversion and possible the color spaces they are using. Most of them shoot in Adobe RGB and use that in their computer workspace.
So far I have told them to make sure that they convert the files to sRGB before printing - to save the RAW as a PSD file and convert it to a JPEG using image processor with the "convert to sRGB" option turned on.
I am now at a point when I am going to arrange a workshop so I would love any help or advice that you may have.
I look forward to all the great suggestions I know I am going to get.
Regards
David Ceruti>> They then print the photos at local photo labs (fuji fronteir machines) ...

Correct.
The Fuji Frontier printer won’t do any gamut conversion.
It just prints "by the numbers", expecting sRGB.
To put it simple.
>> Our requirements are that they hand in a print and an unedited RAW file. Because we are focusing on their photographic technique, they aren't allowed to edit the photos at all...

It is fairly impossible to print from an un-interpreted / unedited Raw file. Editing is the name of the game. Sounds as if the students were shooting Raw + JPG (nothing wrong with this). Only the JPG will be subject to the in-camera setting to Abobe RGB. Should be converted to sRGB before giving it to the Fuji Frontier. If it is really Raw + JPG shooting, it may be easier to set the camera to sRGB. Nothing lost here, because you always have the Raw file to resort to in ACR.

Seeking solution for RAW to jpeg conversion on 1TB disk[s] of images
Please read fully
Greetings,
I have a bit of a dilemma as most might have as well. I have about
3.5TB of RAW images in various directories and seeking an automated
way to convert RAW to jpeg on numerous directories...and go get a
coffee while the process is working (maybe have a nap or two lol)
For many months I have searched for a solution that takes the source
disk (yes disk and not directory by directory) and implements a NEF to
jpeg conversion placing the destination directory on another hard
drive or a separate directory keeping the same source directory
structure. So at the end of the day I would have full sized jpegs and
PSD's in the same directory structure as the source. That make sense?
I have been in other forums and asked but the solutions were using the
typical Photoshop solutions and it does not make a dupe directory
structure as the source.
Any solutions? Ideas?
Thanks,
D.S. HathawayThis is what I'm trying to do. It seems the Image Processor does not handle multiple directories at once.
MainDrive (source)

1234_flag_images

1234_flag2.nef
1234_flag3.nef
WIP <---directory Work in Progress contains
1234_flag1.psd
1234_flag1.jpg
What I am seeking is the above source to be converted to jpeg and
placed onto another dirve/folder/directory with the SAME directory
tree. It should look like:
Another Drive/folder/directory etc (destination)

Make sense?
Isn't there anything out there to handle multiple
(read 100s) of folders/directories and make a conversion as stated
above?
Thanks again,

Am I able to convert RAW files to jpegs on Photoshop Elements?
Am I able to convert RAW files to jpegs on Photoshop Elements?
Hi,
Sorry, but with the information you have given, the only answer I can give is "possibly".
Each camera model produces a slightly different raw format - even different models by the same manufacturer and even if they have the same extension (file type). The latest cameras will not be supported by older versions of Photoshop Elements although there is a converter which can help.
To give you a better answer, we need to know
1) The camera make and model
2) The version of Photoshop Elements that you are using
3) The operating system that you are running on.

Why is quality of my conversion so bad?
I have tried to export from .pdf to .xlsx several times using numerous files and I have yet to receive a converted document that does not require endless corrections.
Columns are not correctly mapped, email addresses are wrong - often missing the "." in .com, most "I"'s are shown as "!", etc.
any advice on how to make this less labor intensive? Afterall, that is why I purchased this tool.Hi ruler65,
Please see Will Adobe ExportPDF convert both text and formatting inf….
The quality of a conversion is dependent on the quality of the PDF (which can vary depending on what/how the PDF was created).
That said, are you converting via the ExportPDF website, or via Adobe Reader? If you're using Reader, please make sure that you have the most recent version by choosing Help > Check for Udpates. If you are converting via the website, clear your browser cache before logging in to https://cloud.acrobat.com.
Please let us know how it goes.
Best,

Automate RAW to JPEG conversions
Does anyone know of an easy/simple way to automate RAW conversions to jpeg?
When I setup an action, it stalls on the RAW file open command and I cannot seem to automate this step.
I have looked at 3rd party s/w like Irfanview but the output quality seems poor.
Any tips from anyone gladly received.
Thanks.grwiffen4760 wrote:
When converting from RAW, can you setup a set of default RAW editor settings that will be applied to each file conversion?
You can address RAW settings two way. You can set default ACR settings for each of your cameras. Open a RAW file from one of your Cameras. Use the Camera profile tab in the ACR Dialog and try out the profiles Adobe supplied for your camera. When you find the one you like best set that one in the profile tab. Then use the other tabs and make the adjustments you would like to see as your defaults. When you like what you have set. Set this setup as your cameras default. Repeat this process using Raw files from you other cameras.
Now you cam also set RAW settings for you RAW files without creatine any image files for groups of raw files. IMO the best way to do this is from the Bridge. The bridge shows you thumbnails of your RAW files and I beleive adjust them under its covers by using ACR and you default settings for RAW files without saved ACR settings. What I do in the Bridge is select thumbnails without saved settings in groups that seeem to have simular exposures and open this group in ACR. One I have all the image in ACR I'll adjust one of them and then sync the rest setting to the setting I just made to the one. Then if some of the thumbnails look like the need a crop I set crop for those one at a time. Finially I'll click on ACR done button. ACR will then record setting for each RAW file either in Sidecar files or in the ACR database.
When you use an Image Processor Photoshop script to process your RAW files into RGB Image files the saved ACR settings will be used for those files that have settings and your default settings settings for files that don't have saved settings. -
Why isn't .jfif not listed in the JPEG file extensions (.jpg, .jpeg, .jpe) Photoshop Elements 12
Problem: Corrupt JEPG files.
Software: Adobe Photoshop Elements 12
Story: On my website I have the option to sell files as instant downloads. I upload JEPG 300dpi images of my artwork for people to purchase is a download. I have done this on Etsy for several years without a problem.
The problem began when I setup a website using Weebly, an online build your own website company. I upload the same files I have used in the past, but when I do a test purchase and download my file it is corrupt. I get an error message in Photoshop Elements that the file is corrupt or missing information. If I let Photoshop open the file, the file it is only half there or lines through the image.
I have been working with a Weebly tech to solve the problem. I sent him the file I wanted to upload. He opened the file on his computer and saved it. Then uploaded to my site, I downloaded it and the file was fine a perfectly clear 300 pdi JPEG file. We were confused. After a few more tests he mentioned he did not have Photoshop and was using Microsoft Paint (light bulb) to open and save the files. His files worked, mine did not.
So I tried opening my files in Paint and saving them in that JEPG format and they work. The only difference i can see between Paints JEPG save option and Photoshops Save Function is that Paint includes the .jfif extension.
Question: Should this make a difference? if so can I add the file extention to Photoshop's list of file types that I can save?
Thanks
MarkThank you I will check it out. I am not sure what information is attached to picture files, but the same file saved in Microsoft Paint works in my situation and the Photoshop file will not. The only difference is Paint supports.jfif and photoshop does not. I might want to go the other way jpg to jififs. or save with to jepg with software that supports jfifs.

How do I control the quality of JPEG images?
I've written a program that scales a set of JPEG images down to various dimensions. I'm happy with the speed of execution, but quality of the images could be better. How do I specify the quality of the JPEG images I create? In graphics editors, I'm given the option of controlling the lossy-ness (?) of JPEGs when I save them, either reducing image qualify to shrink the file size or vice versa. How can I do this programmatically?
ThanksHi Jhm,
leaving aside the scaling algorithm, to save an arbitrary image with 100% quality you'd use
something like the following code snipet below
regards,
Owen
// Imports
import java.awt.image.*;
import com.sun.image.codec.jpeg.*;
public boolean saveJPEG ( Image yourImage, String filename )
boolean saved = false;
BufferedImage bi = new BufferedImage ( yourImage.getWidth(null),
yourImage.getHeight(null),

Graphics2D g2 = bi.createGraphics();
g2.drawImage ( yourImage, null, null );
FileOutputStream out = null;
try
out = new FileOutputStream ( filename );
JPEGImageEncoder encoder = JPEGCodec.createJPEGEncoder ( out );
JPEGEncodeParam param = encoder.getDefaultJPEGEncodeParam ( bi );

Problem with RAW to JPEG conversion
Hello everyone,
I have recently switched to shoot my photos in RAW format. I do the usual adjustments in Camera Raw and the hit "Open Image". Next is that I save my image as JPEG with the Maximum Quality. Once I look at my saved JPEG file though I find that most of them have a lot of noise and seem not to reflect any adjustments that I did to the RAW file. What am I doing wrong?This is the adjustments in "Basic" and "Detail" including the "Before RAW"
After that I hit "Open Image" and then saved it without further adjustments as JPEG, Quality 10. The result of the JPEG when I open it from the Photoshop Organizer is this which I find very noisy.
The disturbing part though is, that the JPEG looks as follows when I search for the JEPG file itself and open it through Picasa viewer. It has way fewer image noise I think. -
