Thanks Mike. I appreciate you advice. Most wildlife photographers shoot in Aperture or Time controlled setting because wildlife is unpredictable and the lighting often changes, particularly if you are in the woods. Manual settings work fine with captive wildlife. I was not trying to light the bird with my flash. I just wanted to create a hi-lite in its eye. Previous posters taught me that if one is using a flash auto ISO defaults to ISO 400 and that is a valuable lesson.

Thank you Mark I will try that Steve but I guess it is easier to not use Auto ISO because now I know it defaults to ISO 400 when the flash is used. Thank You for your help William.

Thank you so much Mike. I will not use auto ISO with flash again.

Thank you so much Mark. When i hit that button before I was asked for the URL of the image I wanted to post. Worked perfectly this time. In the first (dark) image the flash fired. In the second (properly exposed ) image the flash did not fire because it was recycling. I did not make any changes . I guess what I should learn from the experience is that Auto ISO does not work with flash.

I appreciate you reply Tom and i"m sure that would work.but I am shooting birds in the woods and there is no ceiling to bounce my flash. Thanks Mark. I find auto settings useful when I am shooting birds in the woods and the light is constantly changing. I wanted to post the two images I made with exactly the same settings, but I don't know how to include an image in a post. I can focus on a bird and get my exposure right. What puzzled me was when the flash fired, the camera chose an ISO that underexposed the image. The following exposure shot while the flash was recycling was exposed at a higher ISO and the exposure was perfect.

I am shooting birds with a Canon 7D . My settings were Manual 5.6 ,1/250 Auto ISO . I was also using a Canon Flash set at 1/28 th power with a Flash Extender to create a hi-lite in the eye Because of the time it took the flash to recycle some images were made with the flash and others not. For the images that were made with the flash the auto ISO choose 400 and underexposed . For the images that were made without the flash auto ISO choose 1250 and the exposure was on. .What am I doing wrong?

Thanks so much Steve. I will check it out.

I have a Canon EOS RP. I like it and it suits me perfectly for my style of photography. A friend asked me to bring a studio flash unit to help him with family photographs. I was not the shooter, but I brought my RP anyway. The room was dark and when I set my camera to match the flash. (F8- 60th sec- ISO 100 ) I could not see anything through the vewfinder, because the camera assumed I was going to expose without flash.

John, Thanks, Far as I know Lightroom will stack photos, but it will not do focus stacking. I like Photoshop as well.

Thanks for your help. With my limited computer skills, I have had better success with Photoshop than Zerene.

[Mike, Thanks. That makes sense. Not sure how I thought the RP would do it.

I have a Canon MPE 65 Macro Lens. Because it is designed for extreme closeups the depth of field is very narrow.. Focus stacking is necessary to get a whole insect or flower blossom in focus. Automatic in camera focus stacking is a feature of the new mirror less Canon RP. However, when I search it on the net, I am told that it only works with about ten Canon branded EOS lenses and the MPE 65 is not one of them. I would appreciate hearing from an RP owner who has tried the focus stacking feature.

Its a good day when you learn something. I reran the tests according to the suggestions of Mike and William. In fact my 24-105 is sharper than mu 28-135. I was careless and I learned, if you are going to do a test, do it at least a little scientifically and don,t jump to conclusions. Thanks so much for your help.
