    God, thanks for your channel! You must be one of the few photographers teaching how to take shots and edit them in both Photoshop and Lightroom. Most others only teach how to use the camera, not the software, and channels specialized in software don’t cover how to use a camera and take the shots. If that weren’t enough, you get straight to the point. Keep up the good work!

I have neither PS or Lr, favouring Capture One and Affinity Photo for my Fuji photos, but it was still good to see the basics of the process in action. A lot more creativity seems to have gone into today's video edit, too. You're getting quite good at these!! 😂 Who was minding the camera when you were on top of the mountain?? 😉. Great work 👌🏼🎥

    Great tutorial, Mike. Beautiful scenery as always. I am always happy when I remember to focus stack, but unfortunately, I rarely remember to do so. I did take a bunch of photos at my daughter's wedding this past weekend. Now the long process of culling images to find the five or six from the thousand or so I took that she will love. There were photographers there, so pressure is off. I hope you and yours are well, my friend. On another note, how do you like your MacMini?

    • @mikesphotography
      @mikesphotography  Год назад

      Good question Alun! I just do this instead of using the hyperfocal distance technique ... if it's all in focus when you focus on the background, no need for the hyperfocal point, and on the other hand, if the foreground is blurry, just stack it. 😁👍

    • @AK-ContentCreatIon
      @AK-ContentCreatIon Год назад

      HI. If You look at the horizon after using hyperfocal point technique You will see a lot of softness. try not to use more than f8 and as @Alan May said, remember to take smalll focus points within the first first 10 ft or so, but include a foto, as Mike said, of the horizon.

    Great vid! You said you have a Mac mini with 8 gb and it does the job for you? My PC is very old and I’m considering a new computer. Are you happy with the Mini when running both PS and LR or would you do something else now? Lastly, do you do video editing on it too?

    • @mikesphotography
      @mikesphotography  Год назад +1

      Thanks Katz!
      It is fine with lightroom and photoshop ... certain tasks are a little slow and with the really big stitched images, like 9+panos, it struggles and sometimes hits the limit of the 8Gb of ram, but overall I am happy with it.
      If I could get it again, I would go for the 16Gb ram version just to have a bit more capacity when having different programs open at the same time.
      I do all my video editing on it as well. I do use proxies though, so as soon as I import the videos into Premier Pro, I just make low res h.264 proxies so the editing is a much smoother process.
      I hope that helps

    Clear, concise and well illustrated tutorial, Mike! Good tips along the way round out the post. Nice.
    Who makes the L-bracket for your A74?
    I’ve used the auto-focus stack method you illustrate for macro shots. Haven’t ventured into “mask building” version, but will give it a go as needed.
    As I recall the A74, by default, in playback, will zero in on the focus point used to take the shot. Would that help to ensure that all “target areas” have been taken in focus for a series of photos?
    BTW, for iPad display of YT vids, the YT gear icon for vid speed appears in the upper right hand corner😊- just saying. Cheers!

    • @mikesphotography
      @mikesphotography  Год назад +1

      Haha! I did not know that so thanks for letting me know about the gear icon!
      I have the smallrig half cage and I have put a peak design QR plate on the side. This means I can still use the flippy screen and get portrait oriented shots easily!
      I'm still getting to grips with the A7iv ... should really read the manual, but moving house several times has kind of taken priority ... hopefully were somewhere a bit more settled for now so I can finally learn how to use this camera properly!! 😆 I think it might have the option of touching, focussing and taking the focus in one touch ... but I'll have to look into that as well ...

      You can try what you may, in macro photography you will almost always have areas where you can not capture a focused layer of - it‘s a matter of physics. I have yet to see a single macro stack that isn‘t riddled with those halos around foreground subject areas where it is impossible to capture the layer further away completely.

      In that case I would take a set of exposure brackets at each focus point when capturing the photos.
      When editing, I would stack the brackets first, and then focus stack the HDR images that come out of those.
      In theory, as long as you haven't moved the camera at all between shots, you could do it either way, but as the focus stacking could be different between each shot, I'd do the bracketing process first.

    Given that the depth of field increases rather quickly (I won't go so far as to say exponentially) as you focus further into the scene, I take several close together shots up close, and less further away. I might take 3 or 4 in the near-ground/foreground (depending on the focal length), one in the mid-ground, and one for the background. This has always worked very well for me.

    Great video Mike. How do you determine what aperture to use when focus stacking? Or does it even matter?

    • @mikesphotography
      @mikesphotography  Год назад

      Thanks very much Mark.
      With aperture, it depends on what lens you have.
      With my 28-200mm it bottoms out at f16, so I tend to take the shot I want. Then if I see the foreground is blurry, I'll close the aperture down to f11 at most. Then if the foreground is blurry still, that's when I focus stack.
      With the 17-28mm it goes to 22 so I'll take it to f16 and then see what is happening there.
      The wider the aperture (the lower the f number) the less will be in focus from front to back.
      I hope that makes sense.

      @@mikesphotography Thanks for your response Mike. I definitely struggle with choosing the right aperture for landscapes. I try to get everything sharp from front to back and typically go with f16, but if there is not enough light, then I have to slow down the shutter speed which can increase the chances of movement, making the photo soft.

    • @mikesphotography
      @mikesphotography  Год назад

      It is a tricky one isn't it.
      After doing so many corporate headshots pre COVID, I have the opposite problem. I try to keep the aperture wider than I really should. This helps in low light but I have a lot of shots where the foreground is a little blurry.
      Do you mostly shoot handheld?
      If so, try putting the camera in drive mode and fire off between 5-10 shots ... You'll then have a high chance of getting one tack sharp, that's what I do when the camera is struggling with high enough shutter speeds for sharpness.
      I hope that makes sense. 👍

      Unfortunately photography has always been about "messing about at home" from the dark room with dodging and burning to lightroom in stacking and blending images.
      You're right about getting as much right in camera, it's always a good starting point ... but sometimes no matter how long you spend on dialing in your settings, the size of the focal plane that is needed for certain scenes will be outside of the capabilities of any camera/lens combo.

    Please Sir: With APS-C sensor with 20 MP or more, FF with 30 MP or more, DO NOT exceed f8 (some older lenses f11). "Bending" of the light leads to softer images...
    Even if SHARPNESS is really not one of the things that makes a picture "good". If I would be asked to critique Your picture - what You didnt do - I would say this: the softness of the first rock helps this wonderfull coposition. Leading line, subject, feeling... colors (balance of).. very good. I like. The eye tends to look at sharp things. On your rock there is nothing special, so no real reason to show it..

      That is a stretch to get a body and two lenses for under $1000 ... It all depends on how modern you want to go.
      If you don't mind using a DSLR, then something like the Canon 6D second hand would be about $500, and then the 70-200mm f4 comes in about $350 and then something like the tamron 24-70mm ... that would work really well for about $1000.
      If you wanted a more modern camera, then something like the Sony A6100 or the A6300 with a kit lens or the 18-105mm and a wide prime from samyang ... like the 12mm would give you a great range.
      To get great quality with two lenses would mean going second hand though ...
      If you wanted to go new, I'd suggest going for one of the A6000 series cameras, probably the 6100 or the 6300, you can get these for under a $1000 with a kit lens and then maybe a prime from samyang again.
      I hope that helps.
      Thanks for watching 😁👍

    Whenever I hear a landscape photographer mention how good focus stacking works I prepare cringe for the moment he mentions macro photography in the same breath! IT DOESN‘T WORK FOR MOST MACRO SUBJECTS! If you follow that advice for macro photography you‘ll end with detailed shots which are lacking any sense of depth or subject size but more importantly you will end up with horrible artefacts that are impossible to avoid and at the same time are equally impossible to remove without spending days on a single image inventing areas that could not be captured due to the optical laws involved.
    In landscape photography this works because the magnification ratio of the focused elements does not change much (depending on the lens but wrought normally don‘t shoot such subjects with long lenses like the Nikon 70-200 f/2.8 at the long end where it shows considerable focus breathing). In macro photography it works at low magnification of 1:10 (which nobody would call macro photography most of the time) and at very high magnification beyond 10:1 (like the Canon MP/E 65mm lens with additional extension or a reversed wide angle lens).
    Between that, no matter how you achieve focus on your subject layers - using the lens focus or a macro rail - you will get areas of the subject that are occluded by subject elements closer to the camera which inevitably have a bigger magnification ratio when you refocused on the more distant subject area. Those occluded areas will not be included in any layer of your focus stack and thus the final stack will include out of focus areas forming halos around the more distant subject details - regardless if you stack in PS, Helicon Focus, CombineZ or any other focus stacking software. In low magnification it works because the magnification changes through refocusing are negligible, in high magnification the large aperture of the lens when compared to the subject detail will result only in a loss of contrast around the closer subject detail because most of the light will only be subjected to diffraction, not occlusion.
