Your Canon Photos No. 42: 18th to 24th February 2024

Raw and jpeg files are described very well on this page.

TIFF files can be 16 bit, which means that, although large, they contain a lot more details than JPEGs.

As you know, I use PhotLab to process my raw files (it can work noise reducing miracles on these, which are impossible once the raw data has been combined to make the image). I usually save the result as a TIFF, and then import it into Photoshop for final adjustments (simply because I know PS better for doing these) and then save as the jpegs that I upload here.

Meanwhile, here is an impressive cloud for Steve, taken on my walk this week -- just before it rained!

True. What other format do you want to save in?

By the way, I believe that there is a jpg version embedded in raw files, so that you can in fact see what the picture is about. This is the same that the camera makes for you to review what you have shot, when it is only set to save raw files. However, what you then see in DPP or PL is the actual raw file, saved by the camera and converted by the program, and which you can adjust.

For instance, if I compare the jpeg and raw files from my Leica in PL and turn the exposure down, I can recover two stops (2 EV) of over exposure with the raw file, and can see that the equivalent highlights on the out of camera jpeg have been completely truncated and cannot be recovered. This is due to the larger dynamic range of the raw file and is an extremely valuable property.

And my masterpiece of the week:

The text reads: We kindly ask you to keep the gate closed at all times.
