Thanks for looking I have it properly re-sized by simply going to Bridge>Tool>Photoshop>Image Processor then the steps necessary. Worked like a charm.

I perhaps have done this wrong. Any help would be greatly appreciated. An agent has asked for image files in a bit of a rush & I am having trouble. here's been my workflow:

Open Raw & JPEG's (shot in both formats) into CS2,
Image Size, Bicubic Sharper, change res to 72
Save As TIFF, no Compression

First Attempt: I pay no attention to Pixel Dimensions or Document Size. I thought if I lowered the resolution to 72 that's all I needed to do. For example Image Size original might be 12MB RAW, once lowered to 72 Resolution the file size is now 14MB in TIFF.

Next attempt: Image Size: Reduce Pixels to 500 on longest size then reduced to 972 K, but when saved as TIFF size shows as 3.21MB.

First question is , Is that considered a Lo-Rez? Seems kind of high to me. Agents' instructions are: To initiate a low-res submission, simply create jpeg files of all of your images (300-500 pixels on the longest side), include caption info, and send them for review. You can either send images on a disk or refer to the information below regarding our FTP Photographer Upload site for digital transmission.

Second questions is: Why does it show 972K, while Image Size window is open. but 3.21MB after TIFF conversion?

Thanks for any corrective/informative feedback

First of all, if you're submitting low-resolution images, submit only JPEGs, (quality setting 8 or so) not TIFFs. TIFF is generally uncompressed, and file sizes are huge for electronic submission. There is no point in uncompressed image files when you have reduced them to 500 pixels.

Second, for pixel-based image files, always set image sizes in pixels, not inches. When downsizing, the pixel count is the primary limit on image quality, so get in the habit of changing pixel dimensions directly, not linear dimensions like inches or DPI. If you change the linear dimensions or the pixels per inch setting without checking the resample box in the size dialog, all you are doing is changing a tag in the file, and the pixel dimensions will not be changed. THat might be what is happening if your file sizes are >1MB for a 500-pixel JPEG. 100-200K should be the largest file for a JPEG that size.

Thanks Jonathan, your suggestion to submit only JPEG with reference to lo-rez images is good advice as I learned from calling the agency. They actually walked me through the steps. And their suggestion was IQ of 4 would be enough.

As for your comment "get in the habit of changing pixel dimensions directly, not linear dimensions like inches or DPI" what I am interpreting this to mean is when I downsize to the required, in this case, 500x300 pixel per inch in both directions, that I would be in the Image Size window, Resample Image checked, Pixel Dimensions Width & Height, then change this setting to the desired size, from I think it was 3504x2360 roughly all the way down to 500x300 Pixel? This would give me a real image size change. Doesn't this also change the Background Layer, but not the original? This way I would still have the Raw or the JPEG from the camera without adjustments. Yes?


Alternately I don't have any idea how to change DPI within the above named Image Size window. In fact I can only select from fixed aspect DPI selections with my Epson R320, after selectig Print with Preview, such as Fine, Draft, Photo & Best Photo. Don't know what those DPI settings really are. Don't know that it matters since I have no further control over them.
