  2. Look at you accelerating. This is really well done, tricky subject to illuminate but you nailed it. Posted 3 years ago
    1. Really? I thought this photo was so bad that I almost didn't post it. This type of weevil is so hard to photograph. I actually hope that I don't have any more in my bug stash ;P. Their shape makes lighting so hard without lots of reflection. Plus, illuminating all of it is super hard.

      This was the best result that I could get on my first attempt...I used a reflective board above the beetle and a litra cube with softbox on both sides. Then, in front, I used my flash with a big diffuser. The white background turned out better than black in this case.

      1. Reflections are inevitable with such a subject but you managed to make them soft and balanced. It really is well done. An idea I would have in this case is to consider a different background. The foreground is quite believable as being close to natural, but the pure white background kind of takes away from the natural look. But then again, this may not even be the look you're after, so it's just an idea.

        Once again I'd suggest to keep the aperture in mind. In this case it works out fairly well but if you look at your other recent shot of the lengthy beetle, you're using f/4.5. I strongly believe this is far too low. Note how the bottom of the abdomen is out of focus even though it's on the same focus plane. It still kind of works out well because of the beauty of the subject and the eye being drawn to the parts in focus, but I'd still see no reason to use such a shallow depth of field in a controlled situation. I recommend f/16 unless your intention really is to have parts out of focus (as an artistic choice).

        Finally, using both flash and continuous lights combined is an unusual approach. Which in no way means its bad, because it worked out really well. The unusual aspect of it is that flash typically is far more powerful than continuous lights so it may cancel out continuous lights. Whether it does depends on tons of settings, so hard to tell.

        Consider this feedback as feedback for the sake of feedback, you're doing a really great job.

        1. Ohh, good idea about the white background. Black wasn't working, but I should have tried something more natural and I think that is a big reason that I don't like this photo. The stick on white is too weird.

          I definitely want more of it in focus -- I have a problem though when I select f/16. I don't get enough light and am not sure how to fix that bc I feel like I am already blasting the subject with lights. Usually, what I do is take a whole bunch of photos with different light intensities, and different camera settings, hoping that one will end up decent. I had set the aperture to f/16 for some of the shots, but they were SO dark. This is a similar problem that I have when shooting in the forest. Not enough light with a small aperture opening. My ISO ends up in the 1000's. Although, I guess I could lower the SS. I am using a tripod.

          So, you don't use a combo of flash and continuous lights?? Lol. I had no idea that it was unusual to use both. Very interesting. Now I need to test this out and use one at a time. I sometimes do this; but, I mostly use both. When using both, I usually use 2 diffusers on my flash AND reduce the brightness with my camera settings. Hehe. I have no clue what I'm doing, but it's fun.

          And, thanks for the feedback! I love feedback. The more honest, the better.

          1. You already answered your own question regarding the image being dark at f/16: use a slower shutter speed. So low ISO, f/16, and then whichever shutter speed is needed to not make the image dark. It's probably best to put your camera in manual mode, this way the camera isn't guessing things.

            For my high magnification photos, I use continuous lights only. The normal macro shots of specimens, I use flash but with a continuous light as a focus light. I tend to use a lot of flash strength so whatever other light in the scene, including ambient light, is nullified.

            There's nothing against using a mix of both though, it's just harder to control. For the record, I have no idea what I'm doing either, but that's the fun part of playing with light. It's just trial and error.

            1. Very good tips, thanks. I have some bugs to shoot tomorrow, so I'm going to try a few things: shoot in manual mode, RAW, and play with lighting. Posted 3 years ago
  3. Great shot Christine. Yep those shiny black beetles are hard to shoot, but you did a good job of it.
    Love the red spots!
