Being slightly harsh, competition rules like that show that the organisers don't really understand how modern cameras work. A very high level and simplified view of how a camera makes a image (JPEG): Light hits the sensor. Every pixel on the sensor produces an electrical reading which corresponds to the amount of light hitting it. The camera converts those ...

Yes of course it can be post processed. It might make it “better.” But it will never make it the picture you wish it was. The good news is that there will be other snakes on other days. Plenty of chances to make better snake pictures lie in the future if you want. There are good reasons to work on pictures that probably can’t be saved. One is to practice ...

There's one most likely choice for the origin and application of this transparency, and a second somewhat less likely one. The likeliest (because of the tape on the edges) is that this was a transparency intended for use on an overhead projector (these were the commonest way to do presentations that involved writing or drawing, live for a large group), and ...

[SAFETY WARNING: You should never image the sun with anything approaching a telephoto lens when it is more than about 10° above the horizon without a solar filter that not only protects against visible light, but also against UV and infrared!! Failure to heed this warning could result in permanent damage to your lens, camera, or eyes!] You don't need an ND ...

Submissions for these types of contests, and even some news agencies, require photos to be submitted as straight-from-camera JPEG files, not as exports of RAW images. This is usually enough to satisfy the submission requirements. Most of the time, people trying to skirt such rules by faking EXIF data, tend to make a mistake somewhere, that is a tell-tale ...

Although I am not a Gimp User, but the process I use in Photoshop will most likely be very similar and it should not take more than 5 minutes to reach a satisfactory result. I will start with the Clock first COPY VIA NEW LAYER, the bottom half of the clock FLIP IT HORIZONTAL to cover the top part of the clock SKEW, DISTORT and WARP this Layer until it ...

The short answer to the question is: it depends. Some award winning images are entirely shot in camera, some are enhanced in the darkroom, some are enhanced digitally. The ultimate question here is one of philosophy. Where does each individual person draw the line of what tools can be used and at what stage of the process before that individual will call it &...

I could come up with the following using Gimp: As you can see, I only removed the reflection at the word "Erkner". You would probably get better results using a RAW version of the photo and by spending some more time. Here is what I did: Open the photo in Gimp and create a duplicate Create a layer mask on the duplicate layer. Fill this layer mask ...

Pretty much everything on 500px that are at the top of various popularity lists have the everlasting stink edited out of them. Every.Single.One. Nothing comes out of any camera on the market looking like CGI for a multimillion dollar movie. That's all I see in the "top images" at 500px. Most of the "Featured Photos & Videos" at ...

It's not exactly the term you are specifically looking for, but looking for information about tethering will get you in the right track. I'm not aware of any generally used term to describe tethering plus applying further post-processing during a shooting session, but some folks definitely do it. Tethering is when the camera is hooked up to a computer or ...

Better than sharpen, you can deblur the image. You could use techniques that are not usual in consumer photography such as blind deconvolution, or patch-based techniques such as BM3D deblur which can deblur from one single image. There are other techniques. You can use Matlab (a standard tool in computer vision) to apply those techniques (implementations of ...

An additional thing to take into account is the code that creates the jpeg has an identifiable signature. The way Photoshop writes the jpeg will be different than the way Corel will write it. Exiftool, for example, has a JPEGDigest tag, which is defined as: an MD5 digest of the JPEG quantization tables is combined with the component sub-sampling values to ...

Note that positive transparent images ("slides") were the standard for stock images in publishing, before the industry went digital. I recall a book (concerning how to sell photos for stock images) describing making a 4×5 transparent positive from an original negative as a high-quality way to give them what they wanted, since a slide made from a ...

Sequator should offer a "select best pixels" option that can be used to reduce satellite interference. Otherwise, there is a somewhat helpful article at Sky&Telescope that points to a statistical method called "sigma rejection" or "sigma clipping" that will reject pixels from a stack of images if they change brightness too ...

The essence of the trick is to stand in exactly the same place. This may require some trial & error. Perspective will be your single biggest issue. You can only match perspective by observing from the exact same point. If from that point you cannot encompass the field of view of the original, then you need to either crop to your new border, or use a ...

Usually re-touching is an add-on. Say something like this: basic retouching, included in a standard shoot, includes face retouching and global corrections, such as skin-tone or overall smoothing (or whatever you are fine with including). Additional retouching is $100/hr, rounded up to nearest half hour. Ask for an estimate. The first question for yourself is ...

This is just an opinion. But nowadays I do not think it is too difficult, as drones have altimeters and GPS. You can add some laser measurements on a boat from you send the drone. So It can be done with some budget. You do not even need GPS. Get a couple of rangefinders. Find two reference spots A, and B, on the island and take some measures so you get the ...

I'd say this was done [or certainly could be done] intentionally in camera. The warm pinkish-orangeish light is likely to be done in post these days, but it's possible to do it with a physical filter. There's actual mist, to throw you off, but it looks like it was just shot straight into a weak sun. This would produce the lens flare [the big circle & ...

In some other answer in these parts it was pointed out that stars can also be small enough to fall onto a single sensel so they can be red, green, or blue (or missing one of the channels) depending on where they fall on the sensor. Stacking images would average their position and mitigate this, removing the color bias.

Of course they are edited. Lets say I have an image. Now: Where will it be seen? If in the subdued light of an entrance hall, I want a lighter print, with some extra separation in the shadows, because shadow detail is hard to see in dim light. If it's going to be in a bright sunny room, I'll take advantage of that to make very rich shadows. I will also ...

I had the same problem - I wanted to change a certain parameter in several photos to the same value. I found 2 ways: As rob j crowe said - you need to edit the photo not in the Develop tab, but in the Library. There, all change is RELATIVE, not ABSOLUTE. Use the plugin Relative Adjustments.lrplugin. For a start, you can use its trial version (it does the ...

Scanning books or their dust jackets? I imagine the scanner lid won't close properly with a book under it, in most types of scanners. One option: Photograph the books with a DSLR or other digital camera, and use a program to auto-crop them. This way you could even crop two or more books at a time, speeding up things. Programs for image cropping and document ...

Shooting tethered with a representation of the original image as an overlay is an option for any camera that allows tethered capture with live view.

This solution has two aspects to it: Taking the photograph from the exact same location, perspective, angle. Overlaying the photograph in post on the reference image. Taking the photograph Using an overlay will help you find the right camera position and focal length to match the reference image. You don't mention which camera you will use for the photo, ...

I can get close, but I'm retaining too much detail overall. Curves, haze/clarity, vignette & split-tone so far, but really need to get the haze right, will look again tomorrow when I've more time & try provide a fuller answer. Trouble with Camera RAW is you can't jump back in to see your settings if you change your mind, it always starts over:\ ...

Photographers are very concerned with accurate capture, and the art of photography deals with inherent limitations in 1) the difference of light perception between eye vs. camera, and 2) the nature of light in subject vs digital screen vs print. Strictly speaking, Polaroid-like photography is probably the only way that you can do live calibration, comparing ...

A well defined disc is easier to achieve when the sun is behind clouds on the horizon. And of course clouds are what catches the color as the sun rises above or sinks over the edge of the earth. Ideally there’s just the right amount of clouds to give whatever effect you are seeking. A simple graduated ND filter can help balance the exposure of the sky and ...

By looking at the exif data, it's possible to know if the image has been developed in lightroom, or comes straight form the camera as a jpeg. This can also be faked. Now, if you take a picture, then look at the result on the camera LCD, you can check the exposure, histogram, white balance, etc. They you can adjust settings and take another picture. ...

To me, this looks a lot like RawTherapee is introducing the issue. I've never had any "seam" like this editing equirectangulars in Photoshop or Lightroom. I suspect using the Gimp to do your image adjustments might also avoid the seam. I don't think it's a matter of doing local/radius edits throwing off the matching, because the seam is thin and ...

I feel this has some post processing, but most of that "misty" effect is due to the angle of the sun relative to the subject. The sunlight bleeds around the edges of the subject and creates that effect. It is generally something people want to avoid. I have had this effect ruin many shots when i try to photograph someone with sunset in the ...
