Can you merge as JPEGs and then save/print as TIFF?...Julian


You asked about TIFF a few weeks ago. A few remedial topics should to be revisited in the context of this follow-up question:

1) The most color data is captured in the original RAW from the camera sensor. Depending on the camera brand, this RAW color data is 12-bit or higher.

2) JPEGs are 8-bit files.

3) Once the color data is discarded from a higher bit-depth, that additional color data (detail) is gone. There are AI techniques / software that seeks to restore a file to a higher bit depth, but it's inventing values that no longer exist in the 8-bit JPEG.

4) Changing a JPEG to another format can effect the compression of the data as well as stopping the ongoing loss of data via re-execution of the JPEG compress when editing and saving an existing JPEG. But, taking a JPEG and saving as a TIFF does nothing to 'improve' a JPEG.

I rarely find the need to create HDR images these days. I have much better success with well exposed raw files edited in software with strong local adjustment capabilities and good noise reduction. I personally use Photolab 4 Elite.

Good local adjustment control on a raw image can pull shadow detail from various places in an image without affecting the overall image. At the same time It can also bring out much more detail in the sky and reduce overly bright areas, again without affecting the rest of the image.

Since pulling detail from shadows can increase the noise in those areas of the image, a good noise reduction feature is important.

For me the end result are much more natural looking images. While, of course, some programs are much better than others for creating HDR, many if not most HDR images don't look natural to my eyes.

The main limitation of shooting multiple images for HDR is the requirement for a completely static subject. Even a gentle breeze or any movement of an animal or other object will be very obvious when three to five images have to be captured and overlaid.

Minor movement such as due to wind can often be cured via the anti-ghosting functions of HDR software.

Depends on what you want to accomplish...

RAW is great for every day photography.

If you want a wider dynamic range, shoot bracketed subs and use HDR processing.

I thought you only shoot JPEG?

HDR is a processed finished photo. It might be processed in camera or using computer software.

RAW is unprocessed, which allows the user to adjust and complete to finish using software.

That is the difference in the simplest form.
