If I understand correctly, the question is: how to constrain skin tones to only brown hues; getting rid of the naturally occurring red patches and bluish tints that some subjects have. I've substituted skin tones using a combination of gradient maps and layer masks. For my answer to make sense, you'll need to be familiar with both techniques. Create a ...


Since version 4.x, RAWTherapee is a compelling alternative. Its functionality and the quality of its filters have substantially improved, with 32-bit float processing throughout in ProPhoto RGB, CIECAM if you want that, and huge amount of intelligent features - its automatic chromatic aberration correction is better than anything you can achieve manually in ...


raw != image You have to realize that raw files are just data. Interpreting that data in a certain way can lead to images. Each photo editing software will interpret the data differently or even jsut display an embedded jpeg image. That's why the images I have do not look similar to what you have. I did this with Lightroom 5 very quickly. I explain each ...


The whole point of RAW is that the file contains more dynamic range than is typically rendered in previews or default images. You need to first "develop" the RAW file in any post-processing software that can handle the RAW format to set the exposure. By that process you can correct over- and under-exposure to some degree. If the highlights are truly blown ...


Canon cameras are uniquely suitable and cost effective for such a task and I'll explain why. I believe Canon released some information regarding their firmware which has resulted in a couple of custom firmware projects for Canon cameras. Most notable would be the "Canon Hack Development Kit" (CHDK) It will add some very ...


This thread is just what I needed, an experiment to illustrate bad handling of PNG files on this forum. Perhaps someone will find the experiment amusing. Here comes a PNG file: The editor thread shows a file, the result window does not!!!!!!!!!!!!!!!!!!!!!


DP, First and foremost, use your SHUTTER_COUNT in your filename. My D800E uses 4 digit numbers which I can roll over in not much more than a day. They SCount should never roll over in the useful life of the camera as it should go into the millions whereas the shutter is usually rated at 1/4 million or less. This way, you won't have DAP_9999 and DAP_0001 in ...


Adobe Lightroom can create stacks of images based on their capture time(which is a variable you can modify). So I use that. More information on the topic: Adobe Help - Automatically Stack Images


One common way to do this is before and after a bracketing sequence, take a quick shot of your hand. That stands out and you know that all the shots between the two "hand" shots are the bracketing sequence. You can use the ground, sky, anything that easily stands out in a thumbnail Another thing that helps is to change what is often the default sequence ...


How to do a mask with a gradient (first question) Use the Layer Mask. Menu Layer -> Mask -> Add Layer Mask. The menus "Edit Layer mask" and "Show layer mask" let you select and draw to the mask instead the layer directly. You are able to use all tools like gradients, brushes and even filters like gaussian blur to have a nice gradient around your freehand ...
