69 Sep 20 Reply This is your best version. I need to get there once this Covid-19 pandemic is over! Sep 27th
69 Sep 20 Comment Hi Geoffrey. Very well done. This is a Wedge-tailed eagle - also called Australian Wedge-Tailed Eagle. This image is better than most on the ones of that eagle I could find on the web.
Such a powerfull bird and stance! I love it!

69 Sep 20 Comment Great image Brenda. I love the title suggestion by Stephen. I also agree with Mervyn that it would be nice to tone down the bright yellow area if possible. Really nice improvement from the original to the submitted version.
Best of luck with your submission!

69 Sep 20 Comment Jacob, I am really impressed with your terrific improvements from month to months - really amazing, and still using an iPhone! Very well done. I am looking forward to your next submissions! Sep 17th
69 Sep 20 Comment Amazing image. Almost looks like a martial art fighter focussing prior to strike! Wow.... Love it! Sep 17th
69 Sep 20 Reply Hi Jacob,
Macrophotography is quite the challange. Please refer to my answers to Geoffrey, Mervyn and Candy with respect to some of the tricks I learned.

69 Sep 20 Reply Thanks Candy. I agree with you. Insect and arachnids are normally quite active unless it is early in the morning and their metabolism is very low... hence the dew! Sep 17th
69 Sep 20 Reply Thanks for these comments Mervyn. It would be extremely difficult to get a dragonfly at a this angle (30 degree or so) without focus stacking and keep everything sharp. Without focus stacking, getting the subject exactly perpendicular to the angle of vision helps to keep everything sharp but then the image might not feel three dimentional.
Another way to help is to use a telephoto with tele-extender (keeping the minimal focussing distance) and/or adding one or more extension tube(s) to reduce the minimal focal distance. In a pinch, I did macrophotography with a 600 mm lens and 3 extension tubes - my lens minimal focal distance of 15 ft or so came down to approximately 5 ft! (PS: I was planning on taking pictures of birds but I always carry extension tubes...just in case I need to get very close to a bug or other small subject!)

69 Sep 20 Reply Thanks Dean. As you know, in close up the dept of field of each image is very narrow (could be less than 1 mm in when the object is 1/2 or less of the sensor size, even at f 9 or so). Furthermore, if the f stop is too high, diffraction can blur the image. These factors makes it easy to get completely out of focus background! Sep 17th
69 Sep 20 Reply Thanks Brenda. I am slowly perfecting the technique - a new "Covid-19" challange!

69 Sep 20 Reply Hi Geoffrey, sorry for this late reply...
Focus stacking can be done with every camera but not all equipment can to "in camera" focus stacking. I know that the Lumix G9 and the Olympus D1X Olympus E-1 mark II and III are capable to do it in camera.
The main use of focus stacking in in Macro photography as the depth of field gets progressively shorter as one gets closer to the photographed objects or creatures.
For macrophotography, the best way is to use a focus rail and take multiple pictures from deep to close (or the opposite) and then using a focus staking program to combine the pictures (obviously, manual focus on the initial end and no no focus adjustment during the scanning of the subject).
Focus stacking can also be used in landscape photography when you have a very close foreground object that needs to be in focus. One could (on a tripod) take a pict in focus of the foreground, one in mid-range and one in background and then combine them.

69 Sep 20 Comment Really nice Dean. I was in that same area early in the morning but as there was no water, there was no reflection. I love this orange light + mirror reflection. My only suggestion would be to have like a little bit more sky to bring the interface of the refection at mid height. Great photography of a rather rare event! Sep 17th
69 Sep 20 Comment Sorry for the delay.... I agree, these are most likely Egyptian Geese. Perfect little family - I personally do not have a preference for the original or the modified cropping. Very sharp throughout. Great image. Sep 17th

70 Sep 20 Comment Wow.... Frans, another great image!
I have seen a lot of old churches and cathedral domes from this perspective. All of them were very nice but nothing came close to this more modern look of the Sagrada Familia ceiling.
Fantastic image, composition, colors, focus, etc... despite being handheld in a middle of a crowd!
Sep 17th
70 Sep 20 Comment Nice work Judy. I totally agree with you. When there is so much to see, it is very difficult to select an area to focus on! You kept a nice soft flow of all these mini falls. I personally like when I can see the sky above the fall and all the way down to the pool of water whenever possible.
I agree with San that the water color was changed in your newer version - or, mabe is just because you cropped tightly on the portion of the pool where the water which did not contain the green/blue hues.
Sep 17th
70 Sep 20 Comment I love it San! Another app that I use all the time is TPE and TPE 3D (The Photographer Ephemeris App).
Night photography has it's own challanges: 1) selecting the perfect location (here the Ephemeris is of great help) - this location changes every day as the earth is moving! With the Ephemeris App, one could plan days ahead. 2) Getting there during the day time to make sure that you know the area and that you can get back safely (unless you are sleeping on site (campground, van, boon docking, etc...) 3) having a headlight (red is better as it is easier to see in the dark once you turn the light off) and 4) propper cloathing (keeping extra batteries on your body inside your coat, gloves, warm boots if needed, etc...
Night photography needs planning, and then, clouds can ruin everything!
Great composition - love it!

70 Sep 20 Comment Fantastic image eather. I love both the B/W and the color versions but for different reasons. The B/W adds to the mood, but there is a nice diagonal line (from top left to bottom right) that separates the blues on top right from the rusty colors on the bottom left. This contrast in colors also corresponds to what is "in" the house (of what it is left of it) and what is on the other side of the window (outside). I find that the textures are really nice in either mode. Very nice. Sep 17th
70 Sep 20 Reply Thanks for your very kind comments Lamar - appreciated. As you know, some of the advantages of getting to the scene early is that there is no rush to get it right (as long as one has appropriate clothing for this time of the day, and tricks to keep the bugs away). Furthermore, no crowds that gets in the way.
Interestingly enough, during the day, this scene is not as serene as there is a quarry accross this little lake (not seen here partly due to the darkness. P.S.: I did not cheat by removing it! - just hid it behing the trees in the middle...)
Sep 17th
70 Sep 20 Reply Thanks San. I totally agree with you - the world is in turmoil. At that time of the day, the only other people that might be around would be the avid fishermen! Sep 17th
70 Sep 20 Reply Thanks Larry! I love to catch this pre-dawn blue hour, even if I needs to get up really early to catch it (this lake is approximately 1.5 hours away from my place!) Sep 17th
70 Sep 20 Comment Great image Lamar,
I love the pastel color palette from top to bottom during the early morning. The fog adds to the mistery. The sparse patches of grass with the mirror reflection as well as the clouds with reflection adds to the calmness of the scene. I agree with San that the bridge is a bit distracting but I am pretty sure that removing it would be cheating?!
Nicely done.
