4	Nov 21	Reply	Bill, iPhone infrared ?? Very interesting rendition.	Nov 20th
4	Nov 21	Reply	CONGRATULATIONS !!!!	Nov 11th
4	Nov 21	Reply	Ian, big difference and improvement indeed. Well done.	Nov 11th
4	Nov 21	Comment	Bill, perfect image for a calendar: super sharp, great composition, beautiful colors. Interesting contrast from the classic (carousel) and the super modern (Sky scrapers). Would love to see the B&W interpretation to be used in the calendar. Did you leave the extra empty space bellow the reflection to keep the correct proportion for the printing ??	Nov 8th
4	Nov 21	Comment	Guy, interesting PP, specially the idea of rotating the image 180 to make it look upside up, which seems that the whole bridge and the people are underwater and therefore distorted. As always the options in digital photography are endless.	Nov 8th
4	Nov 21	Reply	Gary, in my monitor still looks oversaturated compared to my PP (Above). Perhaps has to do with color calibration ??	Nov 4th
4	Nov 21	Comment	Gary, I agree with you that the content of the canvas fits the golden Ratio. Your selected vantage point indeed included everything with minimal cropping, still showing some of the distortion created by the 15mm fisheye. I think that the HDR processing, oversaturated the yellows and the greens overall, Perhaps some desaturation is in order. Great composition, and it is sharp.	Nov 3rd
4	Nov 21	Comment	Ian, anhaaa !! last months image found a home very quick. Very interesting blending of the portrait and the background. The end result is very pleasing to my eyes, and is giving Naomi some natural smells to enjoy. Well done. This will pass in creative any time.	Nov 3rd
4	Nov 21	Comment	Erik, the osprey in the front most likely did something he should not have done, or the other osprey is defending his territory and mate. Super sharp image at the peak of the action. Interesting how the one in the front is looking back. The total separation of the birds improves the image.	Nov 1st
4	Nov 21	Comment	Vella, your very complicated mix of steps in your PP really paid off. From a dull image, you were able to bring out a masterpiece in color. The water reflection is also magnificent due to the very quiet water, also the composition giving more space to the reflection rather to the original. Overall very nice image.	Nov 1st

5	Nov 21	Comment	Nick, there is also a flow around the front of the hair which is very obvious. Needs more space around the top and the bottom. Too close to the frame. Practice makes perfect. Keep trying.	Nov 2nd
5	Nov 21	Comment	Barbara, It really surprises me as how sometimes we hold on to a particular image, even though we know for a fact that is not perfect, and still try, with little success, to improve it, and of course; knowing that we have a zillion of images in our library. As you can see here, and with the use of some magic (plethora of adjusting software) two different results were obtained to the likes of some but not for all. At the end of the day, it is the nature of the beholder.	Nov 2nd

6	Nov 21	Comment	Tom, what an impressive and impacting image, tack sharp. I wish you had included a little more information as how it was done as well as the metadata.	Nov 2nd

17	Nov 21	Comment	Marisa, beautiful image of the Queen of the Night flower. It is so impressive the fact that it is a cactus, that the flower only opens at night and that the next day will be completely collapsed and in process of dying. This image is well handled with the dark background, but I think it will look better lowering the brightness, which will give more detail on the petals as well. Unfortunately, no additional data offered.	Nov 2nd

32	Nov 21	Comment	Diana, interesting image of the Liverpool docks, and the B&W interpretation gives more drama to it. Back in April 2020, one of the members of group 4 had an image from the same area, in color; and from a different vantage point. http://psadigital.org/group04/image.php?iid=46466	Nov 2nd

58	Nov 21	Reply	Daniel, today on a second look to the image, I see symmetry broken by the seagull, with the complement of the people walking in the background.	Nov 17th
58	Nov 21	Comment	Bruce, indeed the kids are very curious of what is going on inside the building. It must be something good to draw both kids attention. The contrasting clothing colors makes you look all over the image and try to figure it out. We also are curious to find out what is going on inside. It is sharp, and nicely composed. I think that a tighter crop makes the kids stand out better without loosing context of location.	Nov 17th
58	Nov 21	Reply	Les, the defringe is now inside the Optics slider	Nov 8th
58	Nov 21	Comment	Daniel, you have an admiration for beach images indeed. The human presence in the far background gives dimension to the image. The seagull on the hand rail brakes the monotony of the horizontal lines. The image is sharp. I would have moved a little to the left from your vantage point to have the couple between the two cement chairs and probably also avoid the vertical pole between the chairs. Of course, in street photography not always is possible to change since most of the time we are shooting from the hip.	Nov 2nd
58	Nov 21	Comment	Gloria, great panning shot. It is not easy and it takes a lot of practice. You were able to keep the riders and motorcycle sharp and blur and dark background. The flying hair and the body language of the woman improves the image. Plenty of room in the front to move into. though, they are not wearing protective helmets.	Nov 2nd
58	Nov 21	Comment	Les, very sharp image of the beam, and great composition showing a field (the reflection of the buildings and people) within a field (the background and foreground around the beam). One thing though I see oversaturation of the colors mainly reds and blues with presence of a very strong green fringes everywhere (I do not think it is chromatic aberration, since I have the same lens without this effect) or what is called blooming especially with high-resolution image sensors. Blooming occurs when a group of photodiodes on an image sensor receive more light than they can handle. The resulting electrical charge overflows into adjacent photodiodes, which lose their ability to record a signal that is proportional to the incoming light they receive. This will produce an area in which the image data is corrupted. I took the image into ACR and using the Defringe inside the optics slider and was able to remove it.	Nov 2nd

59	Nov 21	Reply	Ronald, sorry for my ignorance about the game. Thank you very much for the explanation.	Nov 9th
59	Nov 21	Comment	Ronald, rugby is a non familiar sport for me. Have never watched a game. Being from South America, soccer is my thing. Interesting events are going on from behind. You were able to document them. The image is sharp and the colors are very well handled.	Nov 8th
59	Nov 21	Comment	Bruce, again Kudos to you for your cover and article on the last PSA journal. Obviously, you get excellent nature action photos, extrapolated from your experience in sports action photos. I like very much the fact that the FC Dallas player is covering the face of the other player with his hand, and that he is off the ground. Very well handled the blurred background.	Nov 2nd
59	Nov 21	Comment	Hans, well deserved award. This image is full of non stop action all over. Not even three of the Invader's players could stop the Lion's QB. The image is very sharp. There is no amputations around the frame, and there is separation with the players in the background. Perfect timing. The white helmet is almost touching the frame.	Nov 2nd
59	Nov 21	Comment	Gerry, glad to be here and learn a little more about sports photography from the experts: you Basketball, Bruce soccer and Hans about playing soccer in a motorcycle (never heard off or seen that before). We are sharing a basketball image this month. Mine is what I was able to capture, from where I was sitting. Not much planning. From what I read in this group, you really know what you are doing. In this image I find very intriguing the blur around the right hand of # 22 (Taylor) but on second look, I realized that it was the legs of the person sitting in the distance and out of focus, partially blocked by the ball. It looked to me like some sort of powder. I also find very rewarding the fact of the separation from the players of the ones sitting in the back, improves the image. Additionally, player 31 is ready to bite his tongue. The image is sharp.	Nov 2nd

69	Nov 21	Comment	Candy, great capture. Yes the front chick is soft even at f/9 due to the shallow DOF @ 500 mm. The rest of the ducklings and mother are very sharp. Your PP did bring out color and detail. I think that the amputated mother is taking too much space competing with the main subject. A tighter crop still keeps the story, making the little ducks stand out much better.	Nov 17th

72	Nov 21	Comment	Adrian, great BIF image and full of action since it is carrying nest building material. The image is sharp, but a little washed out with no much detail in he feathers. A little ACR magic reducing the brightness and adding some light to the shadows, resolved the problem bringing out detail in the feathers and a little saturation in the colors. Good capture.	Nov 3rd
72	Nov 21	Comment	Randy, interesting that you selected to crop the wolf and leave plenty of empty space in front of him, placing his head right in the middle. To me, I would have selected a tighter crop in portrait fashion. Image is sharp, and the PP brought out nice details and colors.	Nov 3rd
72	Nov 21	Comment	Marie, what a cute image. Nature at its best. The Racoons are very sharp, and nicely framed by the greenery. Your PP brought out a lot of color and detail. It is sharp. Another good example of what the Nikon D850 can do. Could not have asked for more.	Nov 3rd
72	Nov 21	Comment	Bruce, this is a "CLOSE UP" indeed. I heard in the past about this lady's camp feeding the bald eagles in Homer-Alaska, but never had the opportunity to go. I am not sure if there still is opportunities like the one you had. The eagles look almost as domesticated pets. The degree of sharpness is just perfect. Additionally, you had a great weather day. In katmai we only saw a couple of eagles but very far.	Nov 2nd
72	Nov 21	Comment	Mary, I like more the B&W interpretation rather than the dull blue version. Nice odd number of fish navigating towards the coral reef. Overall, the image lacks contrast. I took it again into Silver Efex Pro 3 and using one of the presets: Full Dynamic made the adjustment. Now you can also see the bubbles at the surface	Nov 2nd
