Sweet I need to learn how to read this
How can you see it's underexposed on that screen? Is that Lightroom?

Hard to say when my laptop is in power saving mode but it looks a little bit too dark.
That histogram shows its underexposed a little and the white balance is a little on the red side.
Yeah I know it was a bit too red, but when I had it more even, the cream and bread was way too yellow
How can you see on the histogram that it's underexposed?
To get the image as bright as possible you want to get the data closer to the right edge of the histogram chart.
You can just use the exposure adjustment in PS to move it closer for that pic. It doesn't need much at all.
Once you move the whole histogram to the right I'd then increase the blue channel just a little. This shouldn't result in a yellowing of anything and will remove the warm, red tint.
I'd adjust blue using either the levels mid tone slider or just a slight upward curve using the curves adjuster.
Thanks for the tip! I just did it. Although I also did it in LR by just increasing the Exposure in the RAW file.
Does it mather which method I use? Is one way better than the other? Or it doesn't mather?

In your case since you have a RAW file adjusting it while in the RAW mode is the best.
Brightness, exposure, levels, and curves are all ways of getting the image brighter, but some might not yield the result your looking for.
brightness and exposure will mostly retain the exact image contrast and simply increase the brightness. Curves on the other hand can increase contrast while increasing brightness and it can be applied to a smaller area of the histogram. This is something I do a lot in my astro photos.
watch the video I posted
Watching it now. Cheers!
looks pretty good.
Is that plate white? If so, your white balance is off as well.
that video is really informative, Thanks!
I suggest subscribing to his podcast, this week in photography.
what is his name or web address?
I love this thread.
I need to take a class on image processing.
ifl, thanks for the link to the video - i've been wondering how to read the histogram information myself. I love this sub forum.
using the curves is NOT the same as just using the exposure slider. the video shows that.
