Output Size question?

NN187838UL2
I am using a 16 meg camera image - my process recipe is set to Jpg, Resolution 300, and Fixed and my processed image has gone from a CR2 size of 11,256 KB to a Jpg size of 2,565 KB with a physical size of app 5 x 8 inches???

I am attempting to obtain the highest res for printing the image at 16x20 inches. Something has changed but I don't have
a clue. Any help out there?

    Have you tried to create a new process recipe? Don't know whether you have Pro, since you can easily manage process recipes from Pro, adding new ones and deleting the older ones.

    I am using pro and I did make a new recipe. I found that if I change the scale to 200%
    my image size goes to 10in x 16in and when I process using that recipe my file does go
    to 8.4 meg.

    I guess that is just the way it is?

    I have recently upgraded to 5.1.2 from 3.7. Lots of good changes and then lot of them I'm not so sure about.

    I appreciate your help.

    You measure size in KB or MB. These are all relative values, not absolute in particular with JPEG. The same is true about the size in inches. This is calculated from the amount of pixels divided by the resolution (dots per inch).

    What you could look at, and report if you like, is what the native amount of pixels is of your raw file and whether you can output that to the same amount when the output recipe is fixed to a scale of 100%. That is your baseline.

    Thanks for your input and are absolutely correct. I started looking at the results using PS4 to convert raw files and it is the same. I did ask the question of support and will attach their reply below.

    Thanks

    Dear Grant,
    please understand that DPI in digital images is basically the same as metadata. It does not have any real significance on the size of the file until it is printed. Basically I would recommend processing at 100% quality and setting your output size when printing and let the printing software calculate the correct dpi.

    Second way if doing this could be to set the output process recipe tool to "Scale" to width of 20 inches and let it calculate the scale while keeping 300px/inch in the resolution field.

    However depending on your printer and output it you could see that you get better output quality by processing to 100% and then letting your printing software decide the dpi as sometimes the printer software can produce better image quality by calculating an appropriate dpi rather than sticking to 300 at all costs.

    For Capture One 5 and its workflow I would recommend the Capture One user guide available in the menu Help in the applicaiton or our video tutorials:

    I hope this information will provide you with a satisfactory answer. If you have any further inquiries or need clarification on this issue, please do not hesitate to contact us again.
    With kind regards,

    Just had a quick read, but Mark 4's will produce different size CR2 RAW files...might you have inadvertantly set yours to sRAW?
