24 Mar 18 Reply The LED flashlight was very bluish in light-painting and was used only on the train. The rest of the room was dark - no background. The Light box for the focus stacking was much warmer and they turned the lights on in the kitchen to adjust equipment on another project. Jim Mar 17th
24 Mar 18 Reply I just realized a solution to the 45 degree problem for image size on the focus stacking (edited). I had the rail perpendicular to the table. I should have lined up the rail parallel to the train (45 degree) so that the relative size front to back would be maintained - keeping the same distance from lens to train - front to way back.

24 Mar 18 Reply Kayvon, A mask might keep the color of the rock and allow you to covert the rest to B&W. I'm not even at the novice level for masking. Some B&W photos allow for monochrome (plus one color) in the photo, like a red rose (gray stem/leaves) on a newspaper. Click on groups at the top and look for monochrome DD Study Groups in earlier months. Mar 7th
24 Mar 18 Comment I used a remote shutter cable but had to make adjustments. I took these photos in a quickly set up family room. Here are the problems: I have images of the rear of the train that are as sharp as the front, but the rear shot is smaller than the front and do not align in the middle for focus stacking. I was also turning the knob on the rail to take 5cm increments and may have moved the camera slightly. These shots must be more controlled, cement floor, minimum number of adjustments. I pushed the limits with a 45 degree composition. As I mentioned, light painting was blurry at 45 degrees so I settled for 60 degree angle. A 90 degree shot would be tack sharp, but boring - giving only a profile of the front of the train. Mar 7th
24 Mar 18 Comment Lynette, you did a very good job on the catch lights. It adds points of interest that keep drawing us back to her face, balancing the vast blue of the umbrella. I like the original because the blue of her eyes is like the umbrella. Mar 7th
24 Mar 18 Reply Lynette, you can try to zoom in on the eyes in Photoshop to the pixel level. I think there are faint catch-light in both eyes. You can try to use the dodge tool at the 2 pixel level to brighten up what is there. I hope this helps and looks natural. Mar 6th
24 Mar 18 Comment Your choice of B&W makes this photo happen; popping details of the bench as well as each leaf, grass, twig and everything strewn on the trail. I do like the color shades of the rock/boulder in the original. Mar 6th
24 Mar 18 Comment Breath-taking how you got the dawn's light like paintbrushes on the rolling hills. The composition is very well done with repeating lines like a cresting wave. Mar 6th
24 Mar 18 Comment Off her guard, good catch. I like how your focus on her face is tack-sharp and shows the softness of a child. For catch-light in the eyes, if you have someone with you with a free hand, try a reflector to bounce soft light at the face -- but that really gives you away as a photographer looking for a pose. Mar 6th
24 Mar 18 Comment Wow, I am impressed by your sharp details of arms, paddles, and splashes to show the unified strength to paddle faster with the blur of the crowd being left behind. Your panning technique is excellent. Mar 6th
24 Mar 18 Comment I am surprised that the angle of light at sunset produced rich textures with profound shadows for B&W. I'v only thought of sunset golden hour for rich colors. You certainly met the 'challenge' this month. Mar 6th
