69 Aug 20 Reply Agree with you. New skill to practice. With the Olympus and the Panasonic camera, focus stacking can be done in camera fairly quickly.... still.... staying steady is a challenge! Aug 15th
69 Aug 20 Reply Really nice! Aug 7th
69 Aug 20 Comment Fantastic work with an iPhone. I agree with all previous comments. My only other suggestions would be: 1) to crop a little bit more on the right side. This will give the impression that the insect has more room to move forward. 2) I would brighten a little the bottom left corner to give a sense of direction/aim to the butterfly. Aug 7th
69 Aug 20 Reply Thanks Candy.
Macro-lenses can be used as general purposes lenses while offering a 1:1 ratio (or more), unless one uses a macro-lens that does not focus on infinity. (Some macro-lens do not have a focussing ring and must be used with a focusing rail. - These are useless for anything else than macro photography.)

69 Aug 20 Reply Hi Mervyn,
Thanks. Macrophotography offers multiple new challenges. Here, I was very happy that this insect stayed fairly still for a little while as any movement would lead to unsharp edges, or worse, to duplication of body parts! With Olympus cameras, each picture can be saved as a RAW file but the result of the in-camera focus stacking is saved as a JPG. The RAW files can be used in a focus stating program (Helicon for example) and this can allow deletion some of the "moving" captures. Still.... tricky!

69 Aug 20 Reply Hi Brenda,
In macro-photography offers more flexibility in image rotation.
I like your idea and your version but I was more interested in having the insect in his environment and demonstrating that it was really upside down.... I was also attracted by the contrasts in colors.

69 Aug 20 Comment A very interesting and unique landscape. The sky is somewhat boring but over this desert, the clouds are probably really unusual!
Very good idea to use a polarizing filter.
Great work.

69 Aug 20 Comment Very nice portrait of a Lion cub observing from his high point. I really like his intelligent gaze. He looks mischievous!
I find that the bright above his back to be distracting. If allowed, I would darken that area.
He is just beautiful!

69 Aug 20 Comment Nice... really nice. I saw and heard (noisy) these snail-eating birds at a preserve by Fort Myers a few years ago, but not a chick. I love the down on its head and body.
Nice capture and artsy touch-ups.

69 Aug 20 Comment Fantastic shot. Really tells a story. Thanks for being so patient.... I know, to get a shot like this, you need to be extremely patient...
Thanks for sharing.

69 Aug 20 Comment Hi Geoffrey. Interesting point. I agree, the noise was minimal.
Well: Macro-photography opens the doors to a whole new set of challenges.
1) The closer you are to your subject, the shallower is your dept of field. This is why focus-stacking is frequently needed to keep everything sharp.
2) The closer to your subject, the more shadow you create with your body, your camera, and your lens.
3) Any movement of your subject can lead to multiple positioning of the antenna, limbs, wings, etc...
That day, I was not "really" prepared for this type of picture and I did not bring my macro-flash. I did not have a lot of light to work with and I did not want to slow down my shutter speed too much(even with the in-camera image stabilization - the bugs are not remaining still..... so.... I had to increase my ISO.

70 Aug 20 Reply Thanks Frans for your kind words. Nice to experiment!
As I am an early bird, I am progressively getting found of predawn images. Did not think about layering the 2 images... but very interesting idea. I need to become more creative!

70 Aug 20 Comment Nice image. I was wondering if some of the bracketed images could help bringing a bit more details of the wall surrounding the door. This image is very well framed and the pedestrian is a really nice addition, but I am also curious on seeing a version where you would decrease the "shadow" and "black".

Another spot I would like to visit once possible.

70 Aug 20 Comment Nice image. I agree with the above comments. Really nice improvement done from the original capture. I personally like horizontal views for this type of image as it would show more the glorious colors of the sun and its effects on the clouds as well as a better view of the beach. This is unfortunately not always possible due to the presence of people, buildings, etc.. that are interfering. Aug 21st
70 Aug 20 Comment Nice. I personally would like the flowers to be brighter but I like all the above versions. I think that having more room on the left would give a better idea of the size of this scene. As the sky is interesting, maybe having more sky would also be nice.
Aug 21st
70 Aug 20 Comment This is a really nice image. I like the setup. The starburst sun withing some clouds with JR silhouette right by as well as the plays with lights and shadows on the center and right side of the image. Your friend demonstrates nicely the size of this bend (and praise the use of a tripod!). The mirror reflection in the right side of the bend is adding to the whole scene. The colors are looking good to me. The grass is not "too green" - This is the "orange hour" after all! Aug 21st
70 Aug 20 Comment Amazing picture of paradise despite very heavy clouds! Nicely done. Aug 21st
70 Aug 20 Comment I agree with all the previous comments. B+W conversion helps focusing on the textures. The shadows are a little strong for my taste. The image conveys strongly the stage of this barn and the natural engulfment from mother nature. Almost looks like this barn is being digested!
Nicely done.

70 Aug 20 Reply Thanks Kathryn. I also prefer the natural color one.
One of the issue I have with the "astro" and "IR" is how to do the white balance as the colors picked are not normally seen with our very narrow light frequency spectrum as humans. I would love to see how birds see their environment!
Aug 21st
70 Aug 20 Reply Thanks. The "Astro" conversion is really aimed at Astro photography. The reason I decided to do an "astro conversion" instead of a IR it that it was offering more flexibility by simply adding the IR filter to get the IR conversion. One can get different IR filters if desired.
As I am not really "creative", I do not have much use for the "astro" image for other things than astrophotography as I prefer "normal" and "IR".
Aug 21st
70 Aug 20 Comment As mentioned, the "No Filter" camera conversion is an "Astro" conversion. Mainly used for the astro photography. I tried a few times during the day to see what would be the result. For me it looks like the trees have more of a "fall color" (even evergreens!).
For astro-photography, the colors are richer, sharper and also some colors are revealed.
This month was more "for the fun of it".

p.s.: If one put a IR filter on a regular camera, the IR look would be very similar. The main difference is that the exposure time would be much longer as the camera filters would try to block the IR spectrum. It would also be almost impossible to see through the viewfinder. In fact, I normally use the "live view" mode when I use that camera.

p.p.s.: The pict marked "Original 1" is the IR. The pict marked "Original 2" is the "no filter - astro conversion" The larger pict is the Bracketed Natural color (with the Panasonic camera)
