trying to be smart except they're clearly using a tripod, locking aperture allows him to ensure he has the correct amount of sharpness and depth of field in his shot, which is why he says to put it at 9.0, the ISO should remain low since you don't want any noise, and from there, since he's using shutter speed on a static shot, he can set it to whatever he wants and it'll have no effect. It's why he says how to get decent real estate shots, this will work for most places with a tripod.

@@LzysGraphics 1. im a designer/ photographer and im aware of all what you said. i do it nearly every day at my job. 2. aperture of 9.0 is not the best for sharpness for everyone. it depends on the lens. if you have a lens with a max aperture of 1.4f, you will have a much lower sweet spot. 3. you forgot, that there are fullframe and apsc cameras. if you put both cameras in the exact same position in the same room and the same time, you will have differences in depth of field. you need to consider the lens and focal lenght. 4. "the ISO should remain low since you don't want any noise..." yes. but why is he saying 250 and not put it very low? thats my point. its too specific to be true for everyone. in fact, if hes using a tripod, the ISO should be 80-100 then, since he can choose what ever shutterspeed he wants, to make it brighter. also you can see in his pictures, he is also capturing the outside. if your backyard is no desert and has moving trees or whatever, because of wind for example, you cant take an aperture of what ever you want, since the trees will be unsharp then. 5. "this will work for most places with a tripod." no it will not. he doesnt say at which time of the day you should shoot for example. and at this time of the year, the sky is cloudy with nearly no sun. its darker. and if your room isnt completely white, like this one, everything changes again. 5. even IF he would help most people with this, why not helping everyong by not going too specific and shortly explain why to use certain settings, so that everyone can adjust it to their own specific scenario.

@@jeffxd5029 First reason is that many Canon cameras perform well at iso 400 (with great colors). Second, even though I could get a good exposure at iso 100, having a higher iso allows me to have a slightly faster shutter speed and less chance for motion blur. The difference in noise is none on modern sensors so you lose nothing in terms of noise performance with a higher shutter speed and gain a sharper image while avoiding potential motion blur. I’ve done work for 3 real estate photo companies and iso 400 for my base image was always the recommendation. Do what works for you though.

I know Canon makes a TS 35mm, but you can also adapt other, wider lenses with a TS adapter and then get in-camera perspective control with a wider focal length. I don't think 35mm is very practical for most interiors unless you are stitching.

When you use ( AP )Aperture Priority Mode you can select your aperture and the camera will automatically set the shutter speed for all 3 bracketed shots , which will all be on the same F stop you choose. ISO 100 is also best for one less grain when post processing and blending all image’s together will always cause some grainy images. You’re using a tripod , not shooting hand held lol.
