Hi,
I'm off in France photographing Romanesque churches with a 5DSR which renders wonderful detail.
I find that reworked RAW images, which seem to save as PSDs, can be huge, up to 130MB. The RAWS are all in the 60MB range to start and the JPEGs in the 20MB range.
How does one reduce such large images to a manageable size, say, to send via email or use in Powerpoint?

Hi again:
I see a series of posts in this vein and your project sounds very interesting.
The question I would have is what post-production software are you using? I use PS and have no issue in saving the final images as JPG files in a vastly file reduced size. For example, I reduced an image of over 80GB to about 6GB - of course there is a reduction in resolution, but that is inevitable if that is the requirement. The alternative is to link to a large file.
If you want to send images of large size, the best thing is to use a file-sharing program such as Google Drive, MS OneDrive, Box, Dropbox, or iCloud Drive.

Dear Trevor, I just saw your response, for which many thanks. I, too, use Photoshop. But what do you do in PS to make such a reduction?
P.S., Do you mean MB and not GB in the above?
Thanks again,
Howard

Good day hvulpus.
What image editing software are you using. I'm going to assume Photoshop since you said the images are saving as a PSD.
When saving an image in PS using the "Save As" command the default is PSD and jpeg is not in the selection drop down pane. You can easily fix this by going into preferences, once open go to file handling (red arrow). look in the main pane on the right and you will see "Enable Legacy Save As", check that box. Now when you use the "Save As" command the drop down will display several options for jpeg, the top jpeg selection is the standard.
Choose your directory, name the file and save. This dialogue box below will appear giving you have the ability to save it as a large or small file. Use the slider or enter a number 1-12 and select OK. File is saved and the size you desire. If you don't want to change your preferences the to save as a jpeg just use the file "Save As Copy" prompt and follow the same process. For me old habit's die hard so I changed my preferences. I'm just used to going to "Save As" when working with files of any type.
Hope this helps.

Dear Marc,
This is incredibly helpful. I used to have saved procedures in PS for reducing batches of large JPEGS. It was incredibly complicated setting of the batch conversions, and every time I changed computers, which is pretty often and I have a bunch of the, I'd have to get help from work IT. This is the first time, however, I've worked with RAW and love what I am able to do with it. Just couldn't figure out the size reduction issue, and thank you much.

For many years, my fast approach to reducing a file to smaller size for email etc. is to use the program IrfanView which is a very versatile program. It can handle display of pretty much any format of image file and one of its features is you can specify a desired file size when saving a jpg file to make it any reduced size you want.
It is a free program but I make annual contributions to the author because I use it so much. It has been my default jpg viewer on my PCs for well over a decade. Just make sure that if you decide to download it, go to the official homepage and not some place that tries to bundle other stuff with the download.
IrfanView is what I use here when decreasing image files to stay within the posting size limit for this site.

I just download the application, I'm going to have to give this one a spin around the block.
Thanks!

Marc,
Be sure and take a look at the plug-ins which add a lot of versatility to the program.

I have been using irfantview as a viewer for more than 20 years probably. It's one of the best freeware I have ever used.

Roger,
Irfanview is my program of choice too.
