Issues with file size and Camera RAW

I am using Photoshop CS5 with all current updates installed on a Mac running Lion. I am having a problem with the handling of the camera raw format (specifically .arw) and how Photoshop handles the format. My first issue is that upon loading the format into Photoshop, the program is cropping a bit of the image from both the left and the right. I have not found a way to stop this from happening. Another issue is file size.A client is having issue with the file size presented.They are providing me an ARW file that is 14.8 MB and I am making edits and provided them with a large jpg from photoshop (jpg qaulity turned all the way up) and they are getting a jpg at 9.7 MB. They are concerned that I am giving them a less than quality result.I know that any conversion from a camera raw format to a high resolution jpg will result in a lower file size and that has been explained however the client has taken the raw format parsed it through Mac Preview, saved it, and resulted in a larger file size than I could provide in Photoshop. This then becomes a confusing situation to handle. Questions:a) How to explain the lower file size happening in Photoshop to the client (what is lost?)b) Why they can use mac preview and get a larger file size that I can at full resolution jpg in Photoshop?c) Is there a way I can make this client happy without moving to a tif file format?d. Why is Photoshop cropping the .arw file? It seems that I cannot adequately explain what is happening to the client and would appreciate any help or solutions. Thanks much!
 
JPG is a compressed format, Tiff is uncompressed, and a Raw file is a data file.
I did a quick test and opened a 23.4Mb raw file then saved as a jpg 9Mb then a tiff 51Mb, perfectly normal

The cropped image is what I don't understand.
Is the Crop tool automatically cropping the image in ACR or is it literally a smaller image, less showing on both sides?
 
Thanks for the input on the file size.
I think he may be confused on how Mac preview is handling the jpg conversion vs. photoshop. Since he's getting a larger files out of the Preview conversion then he doubts that the Photoshop jpg is better. I am thinking it's because Photoshop is just doing a better job of the conversion. Would that be correct to say?

Also yes. The ACR is auto-cropping not resizing. The only way I have found around this is loading the RAW file in preview, converting to tiff then opening the tiff in Photoshop. Weird eh?
 
Just to be clear, the image coming into ACR has already been cropped or does the Crop Tool in ACR activate on an image without your input?
If that's the case you can see what's been cropped out and can also Clear that crop.
See the image:

It's coming in as cropped with no way to fix it that I can see.

Pressing space or opening in preview shows the full image but if it gets anywhere near Photoshop it comes in auto-cropped.
I'm starting to this it's a bug and will be reporting it to Adobe.
 
I'm guessing Mac Preview isn't a raw editor.
If that's the case you're missing the ability to make adjustments in the raw file.

Two things you can try.
Run update and make sure you have the most current version of ACR.
If you do or the update doesn't help you can download the DNG converter.
There both available here:
Adobe Camera Raw and DNG Converter for Macintosh

The DNG will automatically make a DNG raw from your ARW.
See if ACR works properly on the new DNG file.
 
yeah this makes no sense.


transfer the image from the camera to your hard drive.

then load the image from your hard drive into photoshop.

there should be no cropping. if there is, then this is a problem that you need to figure out, because it's on your end.

there is no cropping; this is a problem that you're not figuring out yet. maybe you're zoomed in too close to the image.

as far as .jpeg compression goes, yes, you are going to lose graphic data when saving to .jpeg.

TIFF will preserve the original file to 100% quality.

if your client wants original quality, then explain that you need to email a DVD with the TIFF or RAW files on it.

if he/she wants it through email, then you either need to compress it to .jpeg or use an FTP file transfer software between the two of you to email the full-sized raw format
 
No, there is an issue with the handling of the file.

The format is arw coming from Canon 5D Mark II
In camera we've specified to save both a arw and a jpg and the jpg gets cropped in camera as well.

I have read that it's lens correction and vignette reduction but, it becomes difficult to explain when the client sees the arw file and then I give them a jpg that's clipped.

Sometimes I don't know why they do these things.

At this point I don;t know if it's a bug that I can report or just part of the process of working with these Canon arw files.
 
1. zoom out of the image, it may be that you're zoomed in too close and it isn't showing the left and right sides of the photo

2. pull the slider bar at the bottom of the image over to the left or right.
