Re: Macro Questions

Interesting. But what about the curvature of the lens. Would you have to calculate the curvature of the lens in the distance to the object? Unless you were using a non distortion lens. The physical curvature of the lens is not usually an issue. What matters more is how well the lens is designed to ...

Re: Macro Questions

Now that I've had some sleep, I can resume. :) Regarding formulas: Yes, there are formulas you can use for the situations you described. But, they are just approximations due to the fact that real lenses are not theoretical simple thin lenses and don't behave like one. But, they can get you in the b...

Re: Macro Questions

True macro is 1:1. That means the object photographed is captured on the film at exactly life size. At 1:1, the image projected by the lens on the film/sensor plane is exactly life size. My micro 4/3 sensor is 17.3mm wide. Using a 1:1 macro lens, I should be able to take a pic of a ruler and fill t...

Re: Topaz AI Gigapixel

Interesting. I've enlarged higher resolution crops with preserve details 2.0 and it seemed to have done a good job. Now I'm curious what AI Gigapixel would have done with them.

Re: Topaz AI Gigapixel

Sidd, that technique was recommended in older versions of Photoshop where the interpolation method was 'bicubic'. Adobe introduced a new method called 'bicubic smoother' that gave similar results to the iteration procedure but in a single step. I remember using 'bicubic smoother' in CS6. Photoshop C...

Re: Now that is a macro lens

At close to $1500 USD :eek: , that's not going to be a member of my lens collection. You do get a much wider view and, at f/12 to f/40, you do get a larger depth of field. But, even so, the area of sharp focus is razor thin. I'll stick with my regular macro lenses, Thank You. You can get borescopes ...

Re: Blank Background

The problem is that you saved the clip to your computer in a format that doesn't support transparency. That bakes in the transparent areas as black. Not many formats support transparency. Quicktime using the Animation codec does. You'll need to set the bit depth large enough to include the alpha (tr...

Re: Effect

Yes. Place your flag animation on video track 1 and your footage with the black letterboxing on video track 2. If the black bars were due to transparency, the flag will show through. If the black bars are baked into the image, apply the crop effect to your letterboxed footage and adjust the top and ...

Re: The Strawberry Moon

Civil twilight -- Ok, that's something we can hang our hats on. Civil twilight is defined as the time between when the top edge of the sun is just below the horizon (i.e. Sunrise or Sunset) and when the center of the solar disk is 6 degrees below the horizon. That varies by latitude and date. For Sa...

Re: Audio trouble

I was able to make it louder, but it didn't have the same "feel?" The sound from the other speakers would likely take a different path to reach the microphone. Bouncing off different surfaces will affect the "color" of the sound as the distribution of frequencies in the sound ch...

Re: St Clare of Assisi

Tried it in several different browsers. None display the movie. Microsoft Edge Browser, when Flash is enabled, shows a blank white box where the movie would show -- that's the Flash Player. Right clicking on it gives message "movie not loaded..." Something is definitely wrong. As for Flash...

Re: St Clare of Assisi

The vimeo tag uses the Flash player to view the video. I'm wondering if Flash may be the problem. If not installed or enabled, some browsers will ignore the flash object and not show anything in its place -- like it's not there. Others may show a format not supported message or prompt to install an ...

Re: Rode: Video Mic Me

According to IDC, when you compare market share world wide for smart phones, Android based phones account for about 85% of the market; IOS phones (i.e. the iPhone) accounts for just under 15%. However, 15% is still a huge number of phones. And, because the Android market is divided among many differ...

Re: Colorizing Black And White Pictures

I'd like to add a few comments regarding how I do colorization. First, I always use a separate layer for each color and object. I name each layer to identify what the layer is for. If I need to make a change, it's far easier to identify the specific layer I want and tweak or change the color or sele...
