Improving Your Images !

A browse through the 'Images for Further Editing' lists shows that many being uploaded are not of the full disc label, CD/LP cover etc. PLEASE ensure that the images you upload contain the full image as it makes it a lot easier to bring these images up to site standard. If you have a Windows PC here's some help on how to edit your images to our site standards. The first tutorial covers basic editing using paint.net which many of us use, and can throughly recommend ( and its FREE). The second tutorial covers 'perspective correction' which you are much more likely to see if you photograph rather than scan your images. It uses another FREE program called JpegView. These tutorials have been around for a couple of years, and quite a few members have found that editing their images is fairly simple, and often takes less than an hour to learn. But don't be afraid to ask questions - there are lots of members who can help you! Edited by scrough on 12th Jun 2021, 11:17 PM

Maybe work on getting one edge vertical at a time?

Not bad really, it's only been on the computer for a couple of years and it's only been the last few months iv'e plucked up the courage to give it a go, before that i used to get a migraine just opening the program because it looked so complicated.

I didn't do any fine rotation, just dragged the two vertical edges to align with the grid and then cropped them.Then I rotated 90 degrees clockwise, and repeated. Then 90 degrees anti-clockwise to get everything back to normal.

I can only presume that you start in PdN to expand the canvas to a safe size, or in the case of your own images by taking a sufficiently broad view

	scrough No picture 'cos I'm not into 45rpm :( Member since Jan 2013 3489 Points Moderator	Sounds like you haven't turned off the auto-crop tool Jules, which is detailed at the beginning of the "Simple Perspective Correction" tutorial section! No cropping ever occurs if you set up the perspective tool correctly. But I thought maybe I hadn't gone into enough detail, so I've rehashed another tutorial using your image and a simpler step-by-step guide here working on one edge at a time.

	Juke Jules SUBS Tell me he's lazy, tell me he's slow Member since Jan 2011 4152 Points Moderator	I had given up on JPEGView until I had a particularly bad perspective view of an otherwise clean image so I PM'd Scrough and he put me wise to the simple principles so I thought I'd pass on my own findings when using it according to the links above, When you open the program it has the endearing property of showing all the JPEG files in the last folder you used: just click one to start working, or use CTRL+O. Scrough tells me he never opens or saves any images, he just imports between Paint.NET by cut and paste. Having opened and image I find it best to maximise the window. Find the operation tools: they will brighten up when you mouse-over in two areas towards the bottom of the screen, or right-click and select Transform Image. The important tools for perspective correction are in the upper position, I have no idea what the lower ones do. Start by switching off Auto Crop, then you will need the Perspective tool, Rotate CW and CCW, Reset or Apply, then Save your work. Note that saving does not overwrite the original but creates a new file each time which gives assurance against losing all your work. Perspective correction is by drag and drop at the top, bottom or sides of the screen. Get at least one side true to the grid then rotate and true another side. The effect is very powerful: a basket-case image of a sleeve viewed from one corner became very acceptable after a few minutes' work Edited by Juke Jules on 17th Oct 2021, 12:59 AM

	Magic Marmalade If you're not lost... It's not an adventure! Member since Jun 2014 3778 Points Moderator	I'll just nudge my way into this thread regarding CDs... If you can't circle crop the disc images, I recommend laying the disc on a sheet of white paper / printer paper, so we have good colour matching for site background. >Also, intended an experiment, which I haven't gotten around to yet, of poking a hole in another piece of white paper, to go over the camera of a phone, so you take the picture of the disc through the paper somehow... (Holding the phone with a sheet of paper on the other side is something I've not figured out yet!) ...This will allow photos to be taken of silver discs without reflections of surroundings / unintended selfies, and keep the image even and neutral. Anyone fancy having a go? Interested to see if it's practical, and works. - You'd just have to line up the otherwise reflected camera in the hole with the hole in the disc, to avoid a black spot (camera) on the final image -

	scrough No picture 'cos I'm not into 45rpm :( Member since Jan 2013 3489 Points Moderator	Thanks for the feedback Jules and MM. Its taken a bit of guidance from me, but as you can see above, Jules has now got the hang of perspective correction, so thanks Jules for not giving up! And you've highlighted many things that I haven't had problems with, as different folk use the program in slightly different ways. MM has some good suggestions for CDs, which are useful as CD 'labels' are usually nearly the same size for all. Perhaps a sheet of white paper with a hole cut in it could be laid on top of the CDs?

	Juke Jules SUBS Tell me he's lazy, tell me he's slow Member since Jan 2011 4152 Points Moderator	Photographing through a hole in something is a recognised technique to avoid seeing you, the camera, the lights and everything above you reflected back, but the advice is to use black paper to avoid reflected unwanted stuff. I've tried it myself with a large sheet of black card but holding it steady with a phone on it is difficult. An old single-sided 78 would be a good alternative The trouble is you need to be far enough from the CD disc to avoid radial perspective issues, at which distance you need a big sheet again. Scanning is simpler - dumpster dive for an old one (other discussion threads are available)

	Juke Jules SUBS Tell me he's lazy, tell me he's slow Member since Jan 2011 4152 Points Moderator	I think radial perspective error is the problem with the images I just added on 45cat I don't know how you'd improve on this
