Have you done calibration on your LCD before? If yes, how did you do it?

 

I currently have 2 LCDs running and both are giving me different looking colours for the same photo. I have never done any calibration before and probably that is the solution to ensure consistency in colours displayed by my LCDs.

My grandson Leo was on this particular ride which DID NOT crash but there has been one fairly recently where several swinging cradles got entangled and people were hurt and had to be rescued. I don't know if I would advise anyone to use them now tbh....

I don’t mind saying I have now printed a 12x 18 ins photo of this on my Epson d700 printer and the colours are exactly the same as seen on my PC monitor and iPad. I mounted it in a pure white Matt/ Mount cut by myself with help from Jonathan using a Logan Mount Cutter - (trying to get a mount/matt for an a3+ print has proved impossible )- and framed it in a 24x18 a2 aluminium frame I printed towards my grandson Leo’s birthday next month. He was shown an a4 print before I came on holiday and says it’s brilliant…..the first ever photo/print he likes enough to accept lol…one very proud and pleased mama 😊

I am actually still in awe at the colours and thought the printer would struggle with the front ‘ spike ‘ which close to the wide part goes from purple and pink to a pinky orange before true orange and on to yellow. After help from Marrutt when purchasing Marrutt fine art papers plus lustre paper which this is printed on I am utterly delighted by the results…I thought the printers would struggle but none do. The faffing about over the years with monitor calibration etc etc…I am printing more now which suits while I am unwell. Looking like I need another scope to look at my vocal chords as have very little voice left by the evening…but feel very slightly better atm… Sue :)

Imaged during the night of the 20-21 April this is an image of Messier 13 or NGC 6205 the Hercules Globular Cluster.

 

M13 was discovered by Edmund Halley in 1714 and then catalogued by Charles Messier in 1764 as no.13.

 

Lying between Arcturus and Vega in the "torso" of Hercules the cluster is composed of several hundred thousand stars and is some 145 Lyrs in diameter. The cluster lies at a distance of 22-25,000 Lyrs from us.

 

Nearby is NGC 6207 an edge-on galaxy - visible towards the right frame. A small galaxy IC 4617 is visible halfway between NGC 6207 and M13.

 

Imaged with my Esprit 120ED and a ZWO 2600MC camera (@-10°C & Gain 100).

I spent most of the afternoon running reikan focal lens calibration software calibrating all my lenses to my 7d.

 

THen after a quick tidy up of the house and dinner i found it was 8pm and I hadn't got a photo.

 

I had an idea to do a mega 360 degree stitch of my bathroom, but 69 carefully positioned shots later and an hour with some panorama software it turned into an epic fail.

 

I cast my eye over to the rose on our table by the TV which I've had my eye on for a photo for the past few days.

 

Took about 10 shots repositioning the flash bouce off a wall to get the shadows right on this one.

One from the archives - Dec of 2019.

 

I am having issues with trying to get my monitors calibrated. I have two monitors that I use when working on my photos and usually just use one of them when I do my post processing. I used to have a Spyder Monkey to help with calibration but have misplaced it over the last few years. My photos (to me) look pretty dark on other screens that I view my photos on. To compensate for that I have turned down the brightness on my post processing screen so much that it does not look right at all. Recently I have used the Windows 10 calibration tool that comes with Windows 10 but just do not like the look of what I am viewing on my monitors.

 

My monitors are by no means high quality as one is an Asus and the other a Samsung (bought at different times) and each costing under $300.

 

I am looking for suggestions on getting this corrected.

1) Does this photo "Look" correct with brightness and color. Do my past photos look too dark?

2) Would it be worth getting a color calibration tool such as a Spyder Monkey to try to calibrate older monitors?

3) If new monitors are needed, what monitors would you suggest? (I use a Windows PC) Also keep in mind I do not want to spend high end dollars on a monitor.

 

Thanks for your help with this as it is getting very frustrating..

Some further calibration of the lens and I think it's getting there. The beacon is over a mile from where this picture was taken, so it's never going to. be pin sharp, but still impressed with the detail provided over such a distance.

Messier 106 (also known as NGC 4258) is an intermediate spiral galaxy in the constellation Canes Venatici. M106 is at a distance of about 22 to 25 million light-years away from Earth.

This is the site of the old high school in Winona, Washington. For some reason, I always believed they used the name "Winona" because the town was built on a "wye" in the railroad - literally a "Y", where three track come together. This might be true.

 

There are 18 or so other Winonas in the United States. Few, like East Winona, Wisconsin, are also built upon railroad wyes. The most famous lies along Route 66 ("Don't forget Winona").

 

The earliest seems to be the one in Ohio, founded in 1868.

 

The name is one of the many anglifications of various Native American words. This one appears to originally come from the Dakota peoples' legend of "Lover's Leap" at Maiden Rock at Lake Pepin, Wisconsin.

 

This story is your typical woman was to be forced to marry someone she didn't love, so she killed herself story. In this case, the story was "translated" and heavily embellished by a number of American authors and poets. The first was Zebulon Pike in 1805, though he only told the story, leaving out the names.

 

The first I can find is from 1850 by Thomas Wilson, but that doesn't seem to have received much traction. Henry Wordsworth Longfellow's "Song of Hiawatha" from 1855 however, seems to have cemented it in popular culture, though he spelled it "Wenonah."

 

Longfellow (and probably Wilson) got his inspiration from Henry Rowe Stonecraft, an ethnologist and Indian Agent for the tribes residing in the Wisconsin and Michigan areas in the 1820s. He also was the first white man to "discover" the source of the Mississippi River.

 

In 1822, Stonecraft married Bamewawagezhikaquay (Woman of the Sound the Stars Make Rushing Through the Sky), who went by the name Jane Johnston. She was part of the Ojibwe tribe, and her father was Scots-Irish.

 

She was also a prolific writer, relating and translating many Ojibwe stories. It's likely that her husband heard of the "lovers leap" story from her.

 

The name Winona isn't actually a name at all. It's the Dakota word for first-born daughter.

 

At any rate, in the 1800s, the name Winona was in the popular culture. They all came from the same source, but it's likely that the meaning faded over time.

 

Finally getting to the point, the name Winona was given to this Washington town in 1883 by an engineer on the Oregon & Washington Railroad. He named it after this hometown of Winona, Minnesota.

Early morning on the River Plym.

 

I decided to whip out my under-used grad and ND filters for this image, as well as play around with colour calibration. Overall, I really like the end result.

Those Flickr friends who have followed me for a while will know my love of my Tamron 150-600mm lens. Sometime ago I did a manual fine tuning of my lenses, which improved sharpness considerably. A friend told me that manual calibration of this sort, whilst helpful, was no substitute for proper, software controlled calibration, but I always balked at the cost of around £70 for FoCal, to which I had been recommended. However, I bit the bullet at the weekend and bought it and after following the programme I have now calibrated all my lenses to my camera body. The results have somewhat surprised me, as indicated by this "snap" of the goldfinches, through glass from an upstairs window in bright, harsh sunlight at around 14.15hrs this afternoon. Not a time when I would expect to get optimum results. The sharpness for this shot, based on the FoCal recommendations is better than anything else I have achieved, irrespective of the fact it is through double glazing (I was focused on the centre goldfinch).

 

Have any other of my Flickr friends calibrated in this way and if so what were your experiences? I should love to know.

 

I now want to try all my other, similarly calibrated, lenses in the field!

To My Dear Flickr Friends,

 

Some time back, I purchased a pretty expensive color profiling and calibration suite which has sat untouched, I’m embarrassed to say, because it was so daunting. Now, finally, I’ve gotten about the task of calibrating monitor, scanner, and printer (not sure if I will do the camera, but I can, if need be) and suddenly everything looks ‘wrong’ and so different. All my artwork and photos on my monitor seem to lack the luxuriousness of blacks, the richness of shadows, and the depth of color I’d originally created them with, and as a person with synesthesia, it depresses me in unexplainable ways to see them thusly; as if their souls have been stripped; and I am viewing now only the embalmed remains. (I forgive all who cannot bear with my dramatics right now; when I'm done typing, I will set about the task of several hard face-slaps.) I went to the FAQ section of the manufacturer’s website and my complaint happened to be one of the issues. Their response, however, did not comfort me; apparently it’s the optimal level for viewing all levels of the histogram with hopefully no clipping. They basically said you’ll get used to it.

 

I also felt it necessary to explain why, if you notice my future uploads seeming even darker to you (because now I might be compensating for what I feel is a too-washed-out monitor), it will be because I tend to like it that way; it feels right; it's how my soul 'sees' things: richer, and more vibrant, but also moody, and I also encourage feedback if something's just too dark on your monitor.

 

I had originally made this photo a few months ago, based on how I was feeling at the time; like an alien, out of place. Nothing looked the same to me, anymore. There was a sense of distortion; both in how I viewed myself, as well as in how I thought about things which I'd once believed to be true. I was wondering what my purpose was, and did I even belong to this planet? At times I didn’t even feel real, anymore. Now, all this sounds really more wacky than it really was; it was more like a period of reassessment of my life, and things due to a forced change in course….

 

I never intended to upload it, however, because I'd created this more out of a personal need to express rather than to share, (got a whole hard drive full of that kind of stuff, as I am sure many of you do!) But I find it fitting once again, and felt it an appropriate image for expressing how I feel out of sorts and lost right now. Just from calibrating. How silly is that!! Thank all of you for bearing with me, for this too shall pass!! :P

 

Sincerely,

sMacshot

I am working out my screen calibration on a new monitor. The monochrome picture above looks fine on my new screen but has a lot of contrast when viewed on my old system. Let me know if there are dart blue toned areas on the stem and upper corner. I did not intend this picture to be as heavy handed as it is when viewed on my old (put correctly calibrated screen). I may need to do some further adjustments to my new system. BW is about tone - you have to be able to control the tone.
