LOL. no comment.

#3 shows ISO of 25,600. YIKES!! You used 22 mm focal length and f/20. Estimating 10 feet distance, your depth of field is infinity. Note that in addition to aperture setting, depth of field is affected by focal length and distance to subject. f/18 for #1 is also far more than needed. See:

I see that in your June 18 topic here you used 1/2000 of a second for a non-moving subject. Probably time for a refresher on how exposure works, and the importance of understanding the properties of each of the elements: shutter speed, aperture, ISO.

Next time, do this for indoors:
Flash set on TTL. Camera in Manual mode, ISO 400, F4.5, 1/200 sec. The TTL feature will control the amount of light output for proper exposure on the subject. The high shutter speed will reduce the effect of ambient light from windows and lamps. I also use a Lite-Scoop by Lite Genius to spread the light. You can find their tutorials on YouTube. For outdoors, I use high speed sync in camera settings and can rack my shutter speed up to the max of 1/8000 sec to make sunny backgrounds go dark.

After reading what others have said I think the answer is clear. You do not know how to set the camera when shooting in manual mode.

pictures


Nikon D600, Nikon flash, and using a Sigma 50-250, 3.5-6.3 lens…set on aperture priority for a while then set to manual at abut half way through …. have used it many times before with much better results

I can't think of anything ISO 25600 goes with, except maybe desperation!

Tiny apertures also give huge DoF, not wanted if there are annoying backgrounds.

Also shutter speeds do affect flash photos. Usually as to how much of the Background is lite by any available light. Aperture controls the flash for the Subject. Some UHH'ers might want to look up or review Flash Fill.

REALLY! LOL. I usually leave my cameras at ISO 200, occasionally shoot at 400 or 800. And rarely at 1,200.

ISO noise. Never let your ISO float. Set either aperture or shutter speed and let the other 1/3 of exposure triangle float.

If the subject is not lighted at all and you're far away from the subject and have to use a long telephoto then it would work.

Sometimes these cameras have too many settings and we do get confused. One of the posters above mentioned an easy way to do indoors flash. I set my camera all manually on ISO 400, shutter at 1/200, aperture f/5.6 and the flash to TTL. I have many keepers and this is the most consistent that I have achieved over the years.

"Grain" in a digiCam is circuit noise do to allot of amplification. The higher the ISO [higher cam sensitivity] the less light that hits the pixels on the sensor, the less signal that pixel produces, the more the camera has to amplify that signal to make it useful to the system. If it amplifies allot, the normal BG circuit internal electronic signal that is amplified with the signal coming from that pixel becomes visible as, what you cal "grain". A little over simplified, but that's it. I hope I make sense here. When taking snaps with a flash, set the camera to 200 [up to 400] ISO and see how it looks. There should be no more "noise".

I’m guessing that what you meant was that setting the aperture too small or the shutter to fast resulted in the ISO being to high (if on auto ISO). As I’m sure you know, the ISO setting as nothing to do with how much light hits the sensor - that’s controlled by the shutter speed and aperture only. Not nit picking - just clarifying so the OP doesn’t get the wrong Idea.

Cheers

God bless you; believe me, you are not the first to go out, take a bunch of photos, and then realized that you had something set wrong! There is some great feedback from our fellow hogs, in these responses. Best wishes on your future endeavors!

👍👍. I always shoot manual with a flash. But why do you always use ISO 400 indoors?


Using my Canon 24-70 F/2.8 L lens and my Canon 580 EX II speed light with a Lite-Scoop is good for up to about 30 - 40 feet plus, using 400 ISO, but also is effective in as close as 4 feet without blowing out. Using higher or lower ISO settings would reduce that latitude on one end or the other.

ISO too high would be the culprit is my guess

The high ISO caused the grain.
