Historgram for multiple photos?

[Tintype_18]

I was taking some photos with my T7 a while back. The histogram was on the screen and bfrought a questionto mind. I have played with the histogram on DPP4. Could one use the "graph" on the histogram to adjust settings for f-stop, ISO, shutter speed, etc.? Thanks.

ebiggs1, I agree. I'm still learning the camera and getting to where I like to experiment with different settings. Example- took some photos of wild flowers yesterday. Some were a disaster on manual. A newspaper photographer said he used TV exclusively. Tried it and got some good shots. BTW, I usually take jpg and RAW photos as the T7 will do both at the same time. RAW are taken in case the are edited and submitted to a publisher. Family and other casual shots are jpg only.

"RAW are taken in case the are edited and submitted to a publisher. Family and other casual shots are jpg only."

With today's post editing software there is no reason to not shoot Raw exclusively. The fact you u/l your photos to your computer is all that is necessary as the Raw conversion is seamless and automatic upon import. If you never edit any shot you still have the jpg conversion right in front of you ready for any reason.

Did you know?  When you shoot jpg in the camera your camera does the conversion. So what you may ask?  Well, when it does that conversion it compresses the Raw data and deletes it.  It is gone forever just thrown away never to be recovered. It "guesses" what is important and what is not.  You bet it mostly does a good job but it can't do what human eyes can see and tell the editor to do. On every shot your camera takes, it records everything at its highest resolution.  That is what Raw files are.  That is why they are more editable than jpg, too.

Canon knows this and offers the free for Canon owners the very good editor DPP4. Raw + jpg just tales up extra space on your SD card!

I am not a Tv fan at all. I am also not a manual fan either.  I use Av and P mode almost exclusively. Upon occasion I do need Tv but it is rare. 

I know modern DSLRs have manual mode but they really aren't designed or set up to make good use of it. At times I know it is a must but not very often.  Even back in the olden days the first automatic film cameras like my A1 were Aperture Priority which really is the better choice of the two, IMHO, of course.

Probably the main most reason for Av is, you have full control over the aperture.  Why is this important?  It allows you to have control over the depth of field (DOF). Tv does not.

As a beginner I would advise you to avoid full  manual, for sure, and Tv, probably, for now. When you u/l your photos to the computer, DPP4, you can notice the exposure settings. After a while you will start to see what works and what doesn't work so well. Take lots of shots as experience is the best teacher.

I have DPP4 and learning it. I like to experiment with settings to see the results on Live View. Some are good, others are lousy with nothing showing which leads to the Delete button. My computer will show detail on jpg photos when I right click- date, camera, f-stop, ISO, shutter speed. I take few photos so I don't run out of film.

FWIW, I was reading through some of the guidelines for magazines. One wanted untouched RAW so their staff can edit them. Thought that was unusual. 

Thanks for sharing your thoughts!

"... wanted untouched RAW so their staff can edit them."

I would never send an unedited Raw file to anyone. Never!  Reading is good but reading the wrong things is not so good.  Especially when you are trying to learn.  Sounds like you might want to take some of those places with a grain of salt.

Correct. Not all scenes will have a full 11 Zone range. Ansel’s job would have been a lot easier if they did.
