From RAW to JPEG

[romsan]

Hello,

I just started converting my RAW files to JPEGs.
Here is my steps.

1. Open .PEF file in CS2
2. Adjust it
3. Save for web as JPEG 100%, maximum quality

What I see is that I am loosing lots of details. Also saturation is not that good anymore, pictures looks pale....

What I am doing wrong here???

Thank you,
Roman

Hi.

There could be a few things. First of all, what color space are you saving it to? I think part of this might be related to using save for the web as opposed to save as. With save for the web, you have to make sure you have the ICC Profile box checked, otherwise it will save without a profile, which means there is now no color management. I also believe that save for the web is not well optimized for large images; I know that used to be an issue anyways.

I would recommend that you ensure you are using a wide gamut color space, Adobe RGB works for me, I don't use the even wider Pro Photo while processsing your work. When it comes time to save, I would suggest you use the save as option, rather than save for the web; I believe this will give you better results on large images. Even better would be to work in 16 bits and save as a TIFF or a PSD file, as they are lossless and will give you the most flexibility should you want to do further processing. They are much larger though and will take more storage space and processing power.

Hope this makes some sense.

You are converting the picture to aRGB without converting it to sRGB before saving tit as jpeg. The web browsers (or 90% of them) don't know much about colors and just assume that any jpeg is sRGB). Then the end result is a lack of colors and lustre. Your point No2 isn't very specifik. Among all the adjustments you do I guess you end up with resizing to say 800 pixels on the long side, then sharpen the picture and save it as a jpeg. The details should still be there. Or you can try to explain your workflow in a more detailed way together with an example.

Hi Jonas,

No resizing are done, and the only adjustments are made is Exposure, Saturation, Brightness, Contrast or Saturation.

Even though I do some adjustments the image looks nice and very well saturated.
But once I do save as for web, I loose details and saturation.

Hi Darren,

The thing is in Save As dialog I don’t have JPEG as an option. Some of the options are .PSD, TIFF and some others.

Do I need to change any settings on my image, like different colour profile???

The saturation thing is covered in the earlier replies. loosing a lot of details is something I can't explain. The only thing is that psychology and perception can play games sometimes. A less saturated picture will look softer at a first glance. Apart from that i don't know. "Save as" jpeg without any other alteration doesn't degrade the sharpness. Or so I like to believe as i haven't noticed it myself, ever. Some minor color shifts, yes.

You need to change the image from 16 bit to 8 bit. Image-> mode-> 8 bit will get you there.

Romsan, if "Save as jpeg" isn't available it means you are working in 16-bit mode. Saw for Web is possible as an automatic thing in Photoshop reduces the picture to 8 bits automatically. If you choose Mode--> 8-bit you can do a "Save as jpeg". And as said before, convert to sRGB first.

I gues CS2 has it's own algorithm to conver images for web, once I changed .PEF from 16 bit to 8 bit and then save as JPEG, what a difference...

here what I was talking about

This may or may not have anything to do with it, but in the upper right corner of the preview window when converting to jpeg via the "save for the web" option there is a little drop down menu. I think you want to make sure you are using the document profile here. Just a gues.........

Yes. That's the same thing I have been talking about. Good to see things work now.

all the best,
