      Members Only Fluid Forum View   08/08/2017

      Fluid forum view allows members only to get right to the meat of this community; the topics. You can toggle between your preferred forum view just below to the left on the main forum entrance. You will see three icons. Try them out and see what you prefer.   Fluid view allows you, if you are a signed up member, to see the newest topic posts in either all forums (select none or all) or in just your favorite forums (select the ones you want to see when you come to Fishing Minnesota). It keeps and in real time with respect to Topic posts and lets YOU SELECT YOUR FAVORITE FORUMS. It can make things fun and easy. This is especially true for less experienced visitors raised on social media. If you, as a members want more specific topics, you can even select a single forum to view. Let us take a look at fluid view in action. We will then break it down and explain how it works in more detail.   The video shows the topic list and the forum filter box. As you can see, it is easy to change the topic list by changing the selected forums. This view replaces the traditional list of categories and forums.   Of course, members only can change the view to better suit your way of browsing.   You will notice a “grid” option. We have moved the grid forum theme setting into the main forum settings. This makes it an option for members only to choose. This screenshot also shows the removal of the forum breadcrumb in fluid view mode. Fluid view remembers your last forum selection so you don’t lose your place when you go back to the listing. The benefit of this feature is easy to see. It removes a potential barrier of entry for members only. It puts the spotlight on topics themselves, and not the hierarchical forum structure. You as a member will enjoy viewing many forums at once and switching between them without leaving the page. We hope that fluid view, the new functionality is an asset that you enjoy .

Unsharp Mask for Waxwings???

Recommended Posts

Perhaps this should be in the Photo forum, but it does concern birds. Does anyone have a special formula that you use for unsharp mask on cedar waxwings so that they do not lose that 'molten lava' look to their feathers? Don't know how else to describe it. Buttery? Butter creme? They just have a different quality to their plumage than other birds. And I seem to be losing that quality no matter what route I take. Thanks.

I always thought they had a smoother look to their plumage or a "waxed" look. Almost as if it wasn't real.

Oh, very good! Hence, the name. Never thought about describing that smooth quality as waxy, or why they were named waxwings. Good grief! But yes--how do you manage to keep that unreal quality and still have a sharp image? I'll try to do some selectively.

Well first of all, when you use unsharp mask, try not to set your levels to high. I usually start with amount 30%, radius 1 pixel, and Threshold at Zero. Make sure you use a masking layer when you do this so you can try different settings to get what you are looking for. If you use to much sharpening you will get a white fringe around your bird.

Best rule of thumb for sharpening is to start with a sharp image. Unsharp Mask is really there to help make raw images pop better when converted to PSD, JPG, Tiff, etc.

Hope this helps a little bit. I am not a Photoshop expert but I know my way around it enought to cause trouble.

Good luck.

I'll lasso the whole bird and the sharp portion of the perch and give the subject a shot of USM or smart sharpening, generally at 75 percent, .7 pixel radius, 0 threshold. Experiment with this so you don't get oversharpened feather edges. This adds a bit of detail and preserves the gentle, mouse gray textures of the main body feathers that waxwings are noted for.

Then, while the whole bird/perch is still selected, I'll hit "inverse" to select everything else in the frame and run noise ninja on it to make the BG even cleaner.

Then I'll lasso the patterns/colors of wings and face and sharpen them further selectively at whatever works (less sharpening for print, more for Web). This makes the wings and eye/bill/face pop.

Thanks so much. I'll give it a try later today--on my way out the door. I'll post them here if I get anything close. I'm afraid light may be my biggest problem. Once again!

Birdsong,

I rarely use a lasso tool and apply sharpening because of the halo issue caused by subtle color shifts in the pixels in your photo and I like to brush in sharpening where I want it. Now many folks posting here do that and do it very well so don't get me wrong it works when precautions are taken.

But as with many things there is more than one way to sharpen a bird smile Two things that will help with eliminating haloing and getting the EXACT sharpening you want with ease. Luminosity sharpening and sharpening on a layer. Luminosity sharpening lessens the color shifts when sharpening your pixels, reducing the halos. Sharpening on a layer with a mask, in other words using your brush tool and painting in your sharpening and then adjusting the opacity of that layer to increase or decrease the sharpening by using a slider is very fast, accurate and again virtually eliminates any of the color shifting which causes the haloing.

Thanks DBL. I can see this is another thread I need to print and put in the notebook. As a painter (sort of) your method has its appeal. You were right. I took my original siskin into USM and haloing started at less than 85%. That was pure carelessness on my part, all that needed sharpening really was the eye. I think my first agenda has to be getting exposure under control so I don't have so many sharpening issues. It will be helpful not to be steaming up my camera monitor waiting for the 'perfect shot.' I have discovered that is why I have to be careful of my poor bottom lip--I get a frost build up on the quick release lever on the ball hinge of my tripod. Too bad breathing isn't just a luxury.

Exactly.

No matter which sharpening regimen is used, the less of it needed, the better, and getting the sharpest and most well exposed image at capture eliminates many challenges in PP.

With your WW image, Birdsong, the one with the berry passing, a big issue is simply that the background is much brighter then your subjects. Overexposing using exposure compensation will expose your subject properly but blow out the sky behind them, or almost blow it out. Using a flash is one way to compensate for the difference in brightness of subject and BG.

There are many times that things happen in front of us as photographers with no warning, and we can't manage the scene in any way but simply have to get the best images we can. I find if I keep the ideas of uncluttered foregrounds or appropriate backgrounds always in the back of my mind, there are times I can take a couple steps in a different direction to make the capture and find better conditions.

    • I am still waiting for something exciting on the Wild front...nothing yet that is for sure...just hoping the same old guys have some gas left in the tank at the end of the year and the "young kids" have finally graduated and can bring it to another level...it's all about the playoffs...getting in is easy...actually making any sort of run is the is where the rubber meets the road. Cullen making a "family" decision vs a "hockey" decision was lucky for Chuck that is for sure and Cullen is not going to bring us to another level...but will be an OK role player and 3rd or 4th liner..probably will fill the jersey of a young guy we have unfortunately..but it is what it is.
    • Which questions?  The one about your education?   Must have been a long time ago since I don't recall it.  I do remember you being a big big huge fan of Chiropractic.   Perhaps you could refresh my memory, it shouldn't take long to post your CV   And I guess you must have missed physics class as well, since in physics calculations of forces are the same no matter the frame of reference, yet you continue to suggest there is a difference between a frame referenced to a person's center of mass, and one referenced to the earth.   I did see this article from a newspaper.... The author must have at least as much qualification as you do http://healthyliving.azcentral.com/muscles-worked-out-using-treadmill-7727.html What Muscles Are Worked Out When Using a Treadmill? The treadmill is a versatile exercise machine that lets users walk, jog and run on flat or uphill surfaces. In addition to providing an effective cardiovascular workout, treadmills also help strengthen the muscles of the legs and butt. Depending on the incline, you can work the front or the rear of your legs more intensely; however, every treadmill workout strengthens both.   The Quadriceps People who walk and jog on the treadmill with regularity gain endurance and strength in the quadriceps muscles. The quadriceps are named for the four large muscles on the front of the thighs; they are the rectus femoris, vastus lateralis, vastus medialis and vastus intermedius. These muscles help the body jump and squat in addition to walking and running. As a result, treadmill exercise applies to more than just working out; it also improves the ease with which you go about activities of daily living. The Hamstrings Like the quadriceps, "hamstrings" is also a collective name for a muscle group. The hamstrings, comprising the biceps femoris, the semitendinosus and the semimembranosus, lie between the buttocks and the back of the knee on the rear thigh. The muscles of the hamstrings are used for power walking and running in addition to squatting and jumping, and -- in general -- the more you exercise on the treadmill, the greater your hamstrings' endurance gains will become. However, according to the University of Wisconsin, roughly a quarter of collegiate athletes who sprint injure their hamstrings. As a result, warm up on the treadmill slowly, and increase running speeds gradually. The Calves The calf muscles of the rear lower leg, comprising the gastrocnemius and the soleus, also work hard during treadmill exercise. According to a study from the Laboratory of Medical Physics in The Netherlands, most of the work performed by the calf muscles occurs as you push off from your toes while walking, running and jumping. You can increase the workload on your calves -- and your hamstrings -- by increasing the incline on the treadmill. The Glutes The glutes make up the muscles of the rear end and, like the leg muscles, help you walk, jump and run. "Fitness" magazine reports that people who set their treadmills to a steep incline increase the workload on their glutes significantly, which increases strength, improves endurance and burns fat and calories. Although the treadmill helps you gain leg strength, the machine is primarily known for its cardiovascular health benefits. As a result, if you exercise regularly on a treadmill you can expect health gains on the inside of your body as well as the outside.    
    • Talk about humor, the original post was from April 2013.    I'm sure the OP has already bought his treadmill, used it as a clothes hanger and re-sold it on C-r-a-i-g-s-l-i-s-t. 
    • Deer numbers on PUBLIC land in NW WI are very low.  Private land seems to be the opposite.  I hunt a number of public areas in Polk County for the last ~10 years or so.   You have to work pretty hard to shoot a deer there.  MFL land is also heavily hunted, but there are lots of opportunities.   Once you learn an area you might do alright, but it is tough if you are new to the region.   Don't expect to get permission to hunt on any farms, in my experience they are all tied up for friends/family.
    • Thanks for the humor. 
    • Thanks for the humor.
    • boys........boys.......................boys.................do you to need a time out? a group hug??????????
    • I'll just laugh when you fall because you have a terribly inefficient movement pattern created by a treadmill.  I don't need any sort of medical background to know that you move on the ground (earth) as you pull yourself forward and push yourself away while on a tread mill your just moving without purpose.  Your body will learn from repetition and when you increase the intensity, your body will develop those patterns faster.   Thank you for the attempted digs, I have addressed every one of those questions in the past numerous times.  Its not my fault you cant remember Dick      
    • To answer your question, at peak eclipse I measured 3500 LUX outside, which is brighter than thick clouds. To fish, what happened today was a typical cloud moved in front of the sun.
